MyGDI EXPLORER

MyGDI Explorer atau Katalog Metadata MyGDI merupakan gerbang utama atau one stop centre kepada pengguna sama ada dari sektor kerajaan, swasta, pendidikan dan individu untuk mendapatkan maklumat geospatial secara online. Tujuan aplikasi ini dibangunkan adalah untuk membolehkan perkongsian maklumat gesopatial secara online, memudahkan carian maklumat geospatial, mempromosikan maklumat geospatial yang dibangunkan oleh agensi, mengelakkan pertindihan usaha pengumpulan data dan menjimatkan masa dan tenaga pengguna dalam mendapatkan maklumat geospatial. MyGDI Explorer memberi peluang penerokaan pelbagai jenis maklumat geospatial kepada penggunanya. Teknologi geospatial dianggap sebagai salah satu cabang teknologi maklumat yang paling berkuasa kerana ia menggabungkan pengetahuan

daripada pelbagai bidang dan sumber. Teknologi geospatial bukanlah bidang yang asing di negaranegara maju kerana ia telah digunakan sejak sekian lama terutamanya dalam tugas-tugas perancangan, keselamatan, pengangkutan, pelancongan, komunikasi, pertanian, perniagaan, kesihatan, infrastruktur asas dan sebagainya. Aplikasi MyGDI Explorer telah dibangunkan pada tahun 2005 dan telah dipertingkatkan pada tahun 2010 dengan ciri-ciri baru yang lebih menarik. Antara kemudahan yang disediakan ialah carian maklumat geospatial, capaian kepada map atau web service, pengemaskinian dan pengesahan metadata secara online serta paparan map viewer. Aplikasi ini boleh dicapai seperti di Rajah 1.

PENGENALAN

Rajah 1 : Antara muka MyGDI Explorer CARIAN MAKLUMAT GEOSPATIAL Aplikasi ini menyediakan ciri-ciri carian dalam pelbagai kaedah seperti kata kunci, envelope search, tarikh kemaskini, temporal search dan content search. Pengguna hanya perlu menggunakan kemudahan carian ini untuk membuat carian terhadap maklumat geospatial yang dikehendaki. Hasil carian akan memaparkan maklumat geospatial tersebut dan pengguna boleh membaca dan menilai keterangan dalam ruangan Metadata Details. Maklumat seperti abstrak, tahun, polisi, nama pembekal data, kaedah mendapatkan maklumat dan sebagainya akan dipaparkan berkenaan

produk/data geospatial tersebut. Selain itu, fail yang mengandungi maklumat metadata ini boleh disalin dan disimpan untuk tujuan rujukan dalam format Extended Markup Language (XML). Maklumat geospatial yang diperolehi dapat digunakan untuk tujuan pembangunan, analisis atau kajian oleh pengguna. Secara tidak langsung, apabila maklumat geospatial mudah dicari atau diperolehi, pengguna menghargai dan menggunakan maklumat geospatial secara meluas. Rajah 2 menunjukkan contoh paparan maklumat metadata.

MyGDI EXPLORER Rajah 2 : Paparan Maklumat Metadata CAPAIAN MAP ATAU WEB SERVICE Salah satu kelebihan aplikasi ini adalah kebolehan untuk memaparkan map atau web service sesuatu peta. Pengguna boleh membuat capaian kepada map service yang diterbitkan melalui perisian GIS seperti ArcGIS Desktop 10, Map Info 10, Quantum GIS, GAIA dan Autodesk Map Guide dan perisian GIS yang bersesuaian dengan standard Open Geospatial Consortium (OGC). Selain itu,

pengguna boleh menggunakan Google Earth dan ArcGIS Explorer untuk overlay map atau web service atas data imagery seperti yang ditunjukkan pada Rajah 3 hingga Rajah 6. Ini secara tidak langsung membolehkan analisis mudah dilakukan pada bila-bila masa dan di mana-mana. Melalui cara ini, pengguna tidak perlu mendapatkan data fizikal daripada agensi pembekal data geospatial yang akan menyebabkan wujudnya kekangan daripada segi penyimpanan data.

Metadata adalah penerangan berkenaan sesuatu data/produk. Dalam aplikasi MyGDI Explorer, pengisian metadata meliputi pengisian metadata berkenaan sesuatu data, servis, dokumen, projek, peta atau sebarang aktiviti yang berkaitan geospatial. Pengisian metadata melalui aplikasi ini telah dipermudahkan dengan penyediaan template metadata mengikut standard MyGDI Metadata Standard (MMS). Standard ini merujuk kepada MS ISO 19115/19139 bagi dataset dan MS ISO 19119 bagi web services. Data Publisher hanya perlu mengisi 17 elemen standard yang mandatori daripada 146 elemen. Data Publisher yang ingin mengisi metadata perlu mendaftar terlebih dahulu. Selepas pendaftaran dibuat, data publisher boleh mengisi metadata mengikut standard yang sesuai dan hantar metadata tersebut. Metadata ini akan disemak dan disahkan oleh administrator MaCGDI serta diterbitkan melalui aplikasi MyGDI Explorer. Pengguna lain boleh melihat metadata yang telah diisi apabila carian dibuat.

Selain menggunakan kaedah ini, data publisher boleh menggunakan fungsi upload untuk muat naik metadata dalam format XML. Kebanyakan perisian GIS seperti ArcCatalog 10 akan menghasilkan metadata dalam bentuk XML. Fail XML ini boleh dimuat naik melalui fungsi upload yang disediakan. Sebelum upload, data publisher perlu validate terlebih dahulu fail XML yang upload agar mengikut MyGDI Metadata Standard. Jika fail ini tidak mengikut standard, fail XML tidak boleh upload dan perlu dibetulkan terlebih dahulu. Untuk tujuan ini, pihak MaCGDI telah menyediakan perisian Metadata Editor Offline (METAFOR) yang boleh dimuat turun melalui aplikasi MyGDI Explorer. Perisian ini boleh digunakan untuk menyemak dan membetulkan metadata serta membolehkan pengguna yang tiada capaian kepada internet untuk mengisi metadata secara offline seperti ditunjukkan pada Rajah 7 hingga Rajah 9. Metadata yang diisi kelak akan disimpan dalam bentuk XML dan boleh dimuat naik melalui fungsi upload dalam MyGDI Explorer.

Rajah 9 : METAFOR untuk pengisian dan penyemakan metadata PAPARAN MAP VIEWER Map Viewer yang dinamakan MyGDIX Viewer adalah salah satu kemudahan yang disediakan bagi pengguna untuk melihat dan overlay map atau web service seperti yang ditunjukkan pada Rajah 10. Kemudahan ini disediakan bagi pengguna yang tiada perisian GIS dan tidak mempunyai

pengetahuan tinggi dalam penggunaan teknologi GIS. Map Viewer yang interaktif ini boleh membuat capaian kepada map service yang disediakan dalam aplikasi MyGDI Explorer atau memanggil servis dari sumber luar yang lain.

Rajah 10 : MyGDIX Viewer MaCGDI telah menjalankan aktiviti promosi dan latihan bagi memastikan semua maklumat geospatial di negara ini diterbitkan melalui aplikasi MyGDI Explorer. Ini adalah bagi memudahkan pengguna mendapatkan sesuatu maklumat geospatial dengan mudah dan mengelakkan pertindihan dari segi pengumpulan data geospatial

antara agensi kerajaan atau swasta di negara ini. Namun demikian, kerjasama semua pihak dari agensi kerajaan, swasta dan institusi pengajian tinggi diperlukan dalam menjadikan MyGDI Explorer satu gerbang utama bagi penerokaan dan perkongsian maklumat geospatial secara online di Malaysia.

PENGENALAN Projek penyelidikan dan pembangunan dalam bidang sumber air amat bergantung kepada perancangan yang rapi termasuklah proses pengumpulan data sehingga projek dilaksanakan dan beroperasi. Kebanyakan projek penyelidikan dalam bidang sumber air sama ada untuk tujuan perancangan atau reka bentuk terperinci, pengumpulan data merupakan satu proses yang penting dan kualiti data yang dikumpulkan akan menyumbang kepada kualiti hasil dan keputusan kajian tersebut. Seth et al. (2006) menyatakan bahawa penggunaan teknik GIS dalam pengumpulan data sesuatu kawasan kajian amat berfaedah. Lanjutan daripada pembangunan Teknologi Maklumat dan Komunikasi yang semakin pesat, teknik GIS juga digunakan secara meluas untuk menyimpan, memproses, mengurus dan memaparkan sesuatu data. Justeru itu, pengaplikasian teknik GIS dan penderiaan jauh perlu digunakan secara efektif untuk menggantikan kaedah pemprosesan yang

lama atau menambahbaik sistem pengumpulan data di lapangan dalam pelbagai peringkat projek sumber air yang berkaitan (Gupta dan Goel, 2006). Kaedah SCS CN diguna pakai dalam kajian hidrologi di kawasan kajian. Ia merupakan salah satu cara untuk menukar kuantiti hujan kepada kadar alir bagi sesuatu kawasan tadahan. Melalui kajian literatur, kaedah SCS CN mampu menghasilkan keputusan secara pantas, mudah untuk dikemas kini bagi sebarang perubahan guna tanah dan ia senang diaplikasi untuk kawasan tadahan yang kekurangan data (Tsheko, 2006; Mishra dan Babu, 2008 dan Leow et al., 2009). Objektif utama kajian ini adalah untuk menghasilkan CN bagi setiap sub-tadahan menggunakan teknik GIS dan penderiaan jauh.

KAWASAN KAJIAN Kawasan kajian yang dipilih ialah Kota Damansara, Selangor yang terletak lebih kurang 10 kilometer dari Tol Sungai Buloh, Lebuhraya Utara-Selatan (PLUS) seperti dalam Rajah 1. Sungai Tambul sepanjang 3.5 kilometer adalah anak Sungai Damansara dan satu-satunya sungai yang mengalir ke dalam kolam takungan

yang terletak di Seksyen 6, Kota Damansara. Keluasan kawasan tadahan yang menyumbang aliran ke dalam kolam takungan adalah sekitar 428 hektar iaitu terdiri daripada perumahan di Seksyen 5, 6, 7, 10 dan 11. Topografi kawasan kajian adalah beralun-alun dengan paras tanah dari 21.72 sehingga 202 meter atas paras laut.

Rajah 1: Lokasi kawasan kajian

Data yang dikehendaki untuk kajian ini termasuklah data hujan, jenis guna tanah, kumpulan hidrologi tanah dan kandungan kelembapan tanah. Datadata tersebut diperolehi daripada agensi-agensi kerajaan seperti Jabatan Pengairan dan Saliran Malaysia (JPS), Jabatan Ukur dan Pemetaan Malaysia (JUPEM) dan Jabatan Pertanian Malaysia (DOA) atau melalui pengumpulan data di lapangan. Teknik penderiaan jauh dan GIS telah digunakan untuk memproses dan menganalisis data-data yang telah dikumpulkan. Perisian yang digunakan untuk pemprosesan data dalam bentuk GIS adalah ArcGIS versi 9.2.

Data guna tanah diperolehi daripada DOA dan telah dikemaskini pada tahun 2002 dan 2004. Peta guna tanah ini adalah kurang terperinci untuk tujuan kajian ini, dengan itu proses pendigitan telah dijalankan bagi memperincikan jenis guna tanah di kawasan kajian dengan menggunakan teknik GIS berdasarkan imej satelit (QuickBird) kawasan kajian dengan resolusi 0.6 meter. Rajah 2 menunjukkan Imej QuickBird kawasan kajian, Jadual 1 pula menunjukkan kategori guna tanah dan Rajah 3 memaparkan guna tanah kawasan tadahan mengikut empat (4) kategori guna tanah utama.

Rajah 4: Peta Kumpulan Hidrologi Tanah (Sumber: DOA)

PEMPROSESAN DAN ANALISIS DATA Pendigitan Kawasan Tadahan Sub-kawasan tadahan perlu dibuat pendigitan berdasarkan peta kontur yang dihasilkan daripada data LiDAR dan kedudukan parit terakhir yang menerima aliran secara graviti. Hassan (2005) menerangkan bahawa kawasan tadahan perlu didigitkan secara manual disebabkan topografi kawasan perumahan yang agak rata dan adalah agak rumit sekiranya sub-kawasan tadahan dihasilkan secara automatik menggunakan perisian GIS. Sejumlah 177 sub-kawasan tadahan telah didigitkan seperti dalam Rajah 5.

Data LiDAR dan SRTM telah digunakan dan diproses menggunakan perisian penderiaan jauh iaitu Erdas Imagine versi 2010. Seterusnya data LiDAR dan SRTM yang telah diproses akan

Rajah 5: Sub-kawasan tadahan daripada Imej LiDAR


dianalisis menggunakan perisian ArcGIS dalam menentukan sempadan kawasan tadahan dan kecerunan kawasan tadahan. Purata kecerunan kawasan tadahan adalah 0.027


Peta kontur dibekalkan oleh JUPEM dalam skala 1:25000. Peta kontur yang dibekalkan memberi gambaran keseluruhan topografi kawasan tadahan, namun ia tidak cukup terperinci untuk tujuan kajian hidrologi yang perlu dijalankan. Dengan itu, data ketinggian yang lebih terperinci diperolehi daripada data Light Detection and Ranging (LiDAR) dengan resolusi 0.5 meter dan data Shuttle Radar Topography Mission (SRTM) dengan resolusi 90 meter juga digunakan untuk rujukan. Data LiDAR dengan resolusi yang tinggi lebih sesuai diaplikasi dalam bidang kejuruteraan seperti merancang jumlah isipadu kerja tanah yang perlu dikorek untuk pembinaan dan kajian perparitan. Teknologi LiDAR merupakan teknologi yang amat berguna dalam proses pengumpulan data (Baran, 2009). Hunter et al. (2008) berpendapat bahawa data bentuk muka bumi daripada teknologi LiDAR adalah mencukupi daripada segi ketepatannya.

HASIL DAN PERBINCANGAN Penentuan Curve Number Menggunakan Kaedah GIS Kaedah SCS-CN telah dikenal pasti sebagai kaedah untuk menganggarkan kadar alir daripada kawasan tadahan yang mempunyai data yang tidak mencukupi (Yip, 2002; Tsheko, 2006; Kannan et al., 2006 dan Leow et al., 2009). CN dihasilkan menggunakan kaedah penderiaan jauh dan teknik GIS seperti yang dicadangkan oleh Mishra and Babu (2008).

bertujuan untuk mendapatkan peratusan guna tanah berdasarkan setiap sub-kawasan tadahan. Seterusnya, CN yang dicadangkan oleh Chow et al. (1988) dirujuk untuk menentukan CN bagi setiap jenis kategori guna tanah mengikut kandungan kelembapan dan kumpulan hidrologi tanah yang berbeza. Jadual 2 menunjukkan CN yang dihasilkan.

Pertama, imej QuickBird kawasan kajian (Rajah 2) perlu didigitkan untuk mendapatkan peta guna tanah menggunakan perisian GIS (Rajah 3). Selepas itu, sub-kawasan tadahan seperti dalam Rajah 5 didigitkan berdasarkan peta kontur yang dihasilkan daripada data LiDAR dan kedudukan parit yang menjadikan tempat terendah untuk aliran dari setiap sub-tadahan.

Langkah terakhir adalah untuk mengaplikasikan CN yang diperolehi untuk sejumlah 177 sub tadahan di kawasan kajian dengan mendarabkan peratusan guna tanah mengikut CN dan kandungan kelembapan (Antecedent Moisture Condition, AMC) berdasarkan peristiwa hujan tertentu. AMC I menunjukkan keadaan tanah yang kering, manakala AMC III menunjukkan keadaan tanah yang lembap.

Peta guna tanah yang telah didigitkan dan lapisan sub-tadahan akan digabungkan menggunakan Geoprocessing Wizard dalam aplikasi GIS. Ia

SPACE INDUSTRY

DEVELOPMENT FOR THE NATION Sr. Shahrizal Ide Research Officer Space Application and Technology Development Division National Space Agency (ANGKASA) Ministry of Science, Technology and Innovation (MOSTI)

ABSTRACT Space industry has been established since the launch of Sputnik into space in 1957. Today, space utilization ranges from traditional space industries such as satellite manufacturing and launch services to more on the downstream industries. These downstream industries represent a huge segment of the space business. For a developing nation who has an ambition to venture into traditional space industry, it is difficult to give an impact to the upstream space industries. The established players from the well-known agencies and countries will certainly dominate the market and be the main choice of all of the associated segment development. Most of the nations invested in space partly for the pride associated with the technological advances that participation in space requires. As a result, the development of the downstream space industries will almost be a certain answer for a developing country in order to join the elite club of space venturers. With an already solid and stable base of manufacturing industries, added with strong research and development backing by its government, a developing nation can one day relish the fruits from the space industry by providing the fusion of downstream space products and services. Keywords: space industry, space applications, downstream sector, policy

Friday, 4th of October 1957, the Soviet Union successfully launched Sputnik I. The world’s first artificial satellite was about the size of a basketball, weighed only 84 kilograms, and took about 98 minutes to orbit the Earth on its elliptical path. That launch ushered in new political, military, technological, and scientific developments. The space industry has received some hundreds of billions of government investment in total. With the technology it brings, millions of mankind on earth is benefiting the outcome of the hard work of space engineers and researchers. In fact, no other technology or scientific breakthroughs has brought more benefits to our everyday lives then the space technology. Space investment indeed has produced assistances directly in the form of telecommunications and remote sensing capabilities and indirectly in the form of technological spin-offs, national prestige and scientific knowledge. Weather, telecommunications, environmental analyses, spatial development and national security are examples of the space technologies upon which humankind relies. Perhaps the most important technology from space is the many satellites orbiting the earth today. The world telecommunication network backbone depends heavily on the communication satellites to deliver information. Even the backbone of internet is carried on the satellites nowadays. Without these satellites, the mobile

Whoever has imagined seeing their house or office or even their car parked in front of the house from space in form of a picture? With the introduction of remote sensing satellite, all those unthinkable things we only imagine to see from space are all now available through the internet. Remote sensing satellites which are orbiting in low earth orbit have revolutionized the way mankind look on the earth spatial attributes. Apart from the original purpose which is for military and security reasons, the application is now used for a variety of ways. Mapping, town planning and agriculture are the main application these images are used. Since

The space industry consists of a fairly well defined set of core elements; launch, satellite, and control which are supporting a wide range of users, including commercial, civil, government, and military customers. For the past two years, the space industry has had global revenues totalling over $250 billion, of which government expenditures represented 31 percent, with the remainder consisting of commercial goods and services. The $175 billion commercial system revenue stream is roughly split 97 percent into services value system, 2 percent into satellites, and 1 percent for launch. Within the $170 billion services sector, commercial satellite operations infrastructure represented nearly 20 percent of total revenue. This infrastructure is comprised of terminals, satellite control ground stations, terrestrial network infrastructure, and other terrestrial based elements. In the year of 2010, as the global economy recovered from a recession, the space industry has maintained its growth. It has been fifth year in a row the space economy showed tremendous growth. The space economy increased by 7.7 percent in 2010, accelerating from annual growth rates of approximately 5 percent that were observed in 2008 and 2009. The space economy increased by nearly $20 billion during 2010, reaching an estimated total of $276.52 billion. Some of this growth came from increases in government spending, but the vast majority occurred in the commercial sector. More on global space activities in 2010 can be more explained in Diagram 1.

GPS or Global Positioning System device can help you determine exactly where you are at any given moment. Not only can a GPS give you the name of the street you might be traveling on, but GPS systems can also give you the exact latitude and longitude of where you are located. GPS technology has developed into a resource that goes far beyond its original goals of navigation and location determination. People with different jobs from many industries are using GPS in ways that make their work more productive, safer and often easier. These days, GPS is finding its way into cars, boats, planes, construction equipment, moviemaking gear, farm machinery and even laptop computers. Scientists, cartographers, postmen, forestry workers, mineral exploration, soldiers, pilots, surveyors, hikers, delivery drivers, sailors, dispatchers, fire fighters, wildlife habitation managers and many others are using GPS as a part of their regular work tools.

Diagram 1: The global space activity value in 2010 The space industry consists of companies who provide the technology (the upstream sector), as well as companies that exploit the technology (the downstream sector). The distinction between the upstream and the downstream segment is not always completely clear, for that there could be companies whose activities could be included in both the upstream and downstream. However, by referring to Diagram 2, we could define the upstream segment as the “Provision of Technology”, and the downstream as the “Exploitation of Technology”. Upstream companies include those involved in the space segment prime and their suppliers, as well as those companies involved in ground segment prime and subsystems and components. Companies who provide support products and services and research and consultancy to these companies are also included in the upstream definition. The downstream sector includes the parts of those companies involved in satellite broadcasting, satellite communications, and satellite navigation. Organisations involved in earth observation (for example, Meteorology Department) and equipment and support product and service providers also form part of the definition of the downstream segment. With the achievement of the country National Space Programme such as RazakSat and the Angkasawan Programme, Malaysia is moving towards developing its space industry potential. The first move is by drafting the National Space Policy. The vision of the policy is to embrace the

space as a strategic sector for national wellbeing towards achieving a fully develop country and beyond. The policy aims to develop the country’s potential in the space sector to support the development of the new economy, and strengthening the national security. The policy will be having a few strategic thrust to achieve its targets. The drafted strategic thrusts are laid out; • To strengthen and expand the local space industry for the economic growth of the nation and to enhance the quality of life. • To accelerate space technology and infrastructure development and create value for economic benefits as well as safeguarding national security. • To strengthen the capacity in research, development and innovation in space science and technology, and to maximize potential for global commercialization of marketable output that will contribute towards national competitiveness. • Exploring space as a frontier to generate new knowledge that helps shape the scientific and technological civilization of the future. • To develop and sustain a comprehensive national legislative and regulatory framework for peaceful, safe and secure utilization of outer space. • To ensure an adequate qualified, talented and competent workforce to develop and sustain space sector. • To effectively engage in international relations and diplomacy to foster and promote international cooperation for the peaceful uses of outer space.

Focusing into a specific area in the space industry development also will be introduced. The focus areas are to ensure the development of the selected downstream industries are well developed and sustainable. As an emerging player in space industry, a nation must identify its limited resources while still targeting to achieve best results. Malaysian is aligning its space sector objectives and prioritises its focus areas in order to contribute to the growth of other industrial sector.

The policy introduced will guide Malaysia in positioning itself in the space industry as one of the Asian major player. It also will promote the right conditions for competitive space industry development; emphasis on education and talent development of human capital and reinforce industry-academia corporation as well as increasing the understanding of visibility and market influence of space activities.

Human capital is a critical issue for developing a space sector. Creating a framework for skills and talent pool development for a long term is critical to ensure the sustainable of the sector. For example, to create a management trainee programme for selected and potential entrepreneurs in the industry for soft skill developments in order to have the optimum balance between the technical expertise staff and management talent.


Nurturing a space-based industry in a developing nation is a tough assignment for a government to handle, but it is not impossible to achieve it with flying colours. Although there are challenges from all sides, the government is more ready in making the first step to venture into the realm of space industry. Development of a space downstream industry will be a starting point before venturing into a major investment in satellite manufacturing and building a launch vehicle.

A SURVEY RELATED TO 3D PROPERTY IN MALAYSIA Tan Liat Choon and Khadijah Binti Hussin Seksyen Polisi dan Garis Panduan Pusat Infrastruktur Data Geospatial Negara (MaCGDI) Kementerian Sumber Asli dan Alam Sekitar Aras 7 & 8, Wisma Sumber Asli No.25, Persiaran Perdana, Presint 4 62574 Putrajaya Land Administration and Development Department Faculty of Geoinformation and Real Estate Universiti Teknologi Malaysia 81310 Skudai, Johor, Malaysia

ABSTRACT A questionnaire survey was carried out on 114 personnel from government authorities and professional companies administering cadastre registration in Penang, Selangor, Kuala Lumpur, Putrajaya and Johore. The aim of the study was to elicit the opinions of the respondents and to appraise their understanding on five study areas, viz. land legislation, land administration, cadastre registration, cadastral survey and mapping issues. The respondents were from six main groups: State Lands and Mines Office, State District Land Office, Department of Survey and Mapping Malaysia, Department of Director General of Lands and Mines Office, State Local Authority (Valuation and Property Management Department and/or Town Planning and Development Department) and Licensed Land

Surveyors. From the present survey, the majority (57.5 %) of the respondents felt that the current land laws failed to define 3D property rights clearly. A high number (83.9%) of respondents thought that new legislation which integrated 3D aspects in cadastre registration, survey and mapping issues would address this anomaly. It is timely that a Cadastral System and Land Registration System that caters to the needs of 3D properties and property rights are instituted in Malaysia. Keywords: land administration, 3D property rights, legislation, cadastre, cadastral survey

Present cadastral mapping is moving towards a system whereby real property can be manipulated, processed, and managed in a 3D environment. This mapping system that is being contemplated in Malaysia provides vital information, including location and ownership for real properties. Whereas the current cadastral information serves present needs, there will be a time when the currently compiled information can no longer cater to more advanced and complex situations that result from innovative developments of the big city. What will inevitably be needed, therefore, is a more advanced system that incorporates suitable legislative and technical solutions in parallel with the implementation of 3D property rights. PROBLEMS AND CONSTRAINTS In Malaysia, there is a lack of proper legislation regarding 3D property in land and cadastral law to cater for the registration of any related legal and technical aspects. Many conflicts seem to exist between laws and statutes with the current cadastral status. Therefore, the rights associated with this registration should be clear in the registry titles issued. For example, Strata Title Act 1985 (Act 318) & Rules and Order allows land to be subdivided into parcels or land parcels based on the area occupied, and National Land Code 1965 (Act 56 of 1965) & Regulations allow air space rights above ground surface up to a maximum of 21 years in form ranging from an absolute conveyance to splitting off individual rights associated with the air space parcel. This is always used in a complication urban multi-level mix development, or in the allocation of property rights concerning underground facilities in large urban areas (Mitrofanova, 2002). There are currently many arguments about the surface under different categories of land use, subdivision, partition and amalgamation; these arguments would evidently be different if 3D

In conclusion, there are many aspects to consider in implementing the 3D property rights of a legal and technical nature. Among these aspects, the core of this research attempt to investigate problems occurs in the Malaysia cadastral system on the legal aspect which can be seen as a foundation for 3D property and its technical aspect. The main legal documents involved are National Land Code 1965 (Act 56 of 1965) & Regulations; Strata Title Act 1985 (Act 318) & Rules and Order; and Building and Common Property (Maintenance and Management) Act 2007 (Act 663). Without proper land and cadastral legislation, such property cannot be formed at all. As a result of this, it has also been necessary to look into the legal systems of other countries, where 3D property formation is already possible by law, and to gain information about what kind of problems are faced there and how they have handled; this is so as to better understand the problems that may occur for countries introducing 3D property rights into their legislation. RESEARCH HYPOTHESIS The hypothesis is that - what contents in general, in the relevant legal documents, documents of title and documents of strata title, certified plan and certified strata plan have to be amended or in order to translate the legal expression from traditional cadastral practice to future cadastral practice for 3D property - whether a new legislation should be introduced or only amend the present legislation where type of provisions in the new 3D property rights’ regulations and practices are needed to be inserted in the National Land Code 1965 (Act 56), Strata Title Act 1985 (Act 318), and the Building and Common Property (Maintenance and Management) Act 2007 (Act 663). On the other hand - what kinds of criteria are required to establish and implement in cadastral procedures where these 3D property rights could affect the Cadastral and Land Administration Systems practices - if the present legislation is adequate, then in regards to the technical aspects.

A SURVEY RELATED TO 3D PROPERTY

property rights are used. Without the possibility of using 3D properties, other legal rights have to be used to allow separate parties to use different parts of one building or property. To make such rights possible, different and new legal institutions have to be created, such as mineral and air rights (Sandberg, 2003). Again, 3D property rights can take on different forms and can vary from full ownership to rights of different extents (Paulsson, 2007).


Forrai and Kirschner (2002) observed that the availability of land use for future and further construction would be both expensive and limited. As the demand and competition for space on the two-dimensional land surface intensifies, the third dimension in property formation assumes increasing importance. In recent times, this third vertical dimension is seen to play a significant role in determining the rights of real property, especially in areas with multi-level mixed development. One of the important issues with regard to real property is the inadequacy of vacant land for rapid development. Many countries, including Malaysia, do not have enough vacant land on the ground surface to cater for the rapid development. This is particularly true in big cities that see increasing numbers of mixed settlements amidst modern skyscrapers.

INTRODUCTION

The objectives of this research are:

From 114 questionnaires that were distributed, 110 (96.5%) were returned of which 106 (96.4%) were valid. The findings focussed on five (5) aspects of the cadastral system: (a) Land Legislation, (b) Land Administration, (c) Cadastre Registration, (d) Cadastral Survey and (e) Mapping. Respondents from PTD, PBT, JKPTG and PTG are required to answer only (a), (b) and (c) where 61 questionnaires are valid while other from JUPEM and LLS are required to answer all questions with a total of all 45 questionnaires valid. Figure 1(a) shows the questionnaires distributed & received while Figure 1(b) shows the questionnaires received & validated from the respondents.

The respondents were classified into six main groups, namely, State District Land Office (PTD), State Local Authority (Valuation and Property Management Department and/or Town Planning and Development Department) (PBT), Department of Director General of Lands and Mines Office (JKPTG), State Lands and Mines Office (PTG), Department of Survey and Mapping Malaysia (JUPEM), and Licensed Land Surveyors (LLS) from Penang, Selangor, Kuala Lumpur, Putrajaya and Johore. The data was then analysed using the quantitative approach. In the third stage, the findings from second stage were used to refine the research instrument further.

In Malaysia, strata and land properties, especially in mixed multi-level development, have become common, so the basis of the land and strata title arrangement is well tested. However, critical research on the problematic areas of land and strata title development in Malaysia has not been sufficient. Although research continues in universities and law-related agencies, most of such studies relate only to the technical aspects of the 3D registration rather than to the legal aspects, the studies by Chong (2006) on the legal and organisational aspects notwithstanding. The current research will attempt to examine and address some of the most problematic issues relating to the future development of multi-level building in mixed development.

Figure 2(a) and Figure 2(b) show that 35 (33.0%) respondents thought that the current land laws defined 3D property rights clearly while 61 (57.5%) responded that they did not, and 10 (9.4%) were unsure. As a result of this, perhaps better 3D visualization should be developed and employed. Seventeen (16.0%) respondents opined that current land laws were being enforced adequately in all types of development and 56 (52.8%) thought the law recognised 3D property rights in mixed developments. Eighty two (77.4%) respondents and 39 (36.8%) respondents respectively thought otherwise. Meanwhile, the remaining respective 7

(6.6%) respondents and 11 (10.4%) respondents remained unsure. It is clear that the modern urban living and land usage needs are pushing hard on the existing laws. As an example, the transport hub at Kuala Lumpur Sentral where railroads, light rail transport systems, hotels, condominiums, car parks and various forms of utilities all crisscross over the same plot of land makes compliance with the provisions of laws difficult on the ground. Indeed, 88 (83.0%) respondents agreed that the practice on the ground reflected the provisions in the current land laws while 13 (12.3%) respondents responded that they did not. 82.1

Based on the analysis from the 106 valid returned questionnaires, 76 (71.7%) respondents were of the opinion that there was no land law which embodied a right for people to hold and dispose of private rights in land in a 3D environment. Nineteen (17.9%) respondents thought the Strata Title Act 1985 provided for this while remaining 11 (10.4%) respondents were unsure. Only 10 (9.4%), 11 (10.4%) and 16 (15.1%) out of 106 respondents thought that the Strata Title Act 1985, the National Land Code 1965 and other land law such as Building and Common Property (Maintenance and Management) Act 2007 were respectively adequate and appropriate to support the land administration system in 3D environment. The remaining respective 86 (81.1%), 87 (82.1%), and 81 (76.4%) did not think so while 10 (9.4%), 8 (7.5%) and 9 (8.5%) respondents were not sure on these issues.

In Malaysia, there is a written Act, Code, Regulation, Rule or Ordinance which includes a right for people to hold and dispose of private rights in land in 3D environment. The Strata Title Act 1985 (Act 318) is adequate and appropriate to support the land administration system in 3D environment. The National Land Code 1965 (Act 56) is adequate and appropriate to support the land administration system in 3D environment. The current land laws are adequate and appropriate to support the land administration system in 3D environment (besides Strata Title Act 1985 and National Land Code 1965). The current land laws define 3D property rights clearly. Are current land laws enforced adequately in all types of development? Do the current land laws recognise the 3D property rights in mix development? Does the practice on the ground reflect the provisions in the current land laws? Are there sufficient legal institutions to enforce land law? Does the law place responsibility for maintaining the 3D land register on a specific minister, government department, institution or official post holder? Land administration officials/surveyors are well versed in the existing land law. What has been your overall level of satisfaction with the Strata Title Act 1985 (Act 318) and National Land Code 1965 (Act 56) regarding 3D property? Do you support the development of a new legislation that integrates 3D properties aspects? Are there any government arrangements in place for the 3D property legislation? This new law should serve to make the 3D property legislation available.

Based on the above survey findings, nearly half, 48 (45.3%), out of 106 respondents were dissatisfied with the Strata Title Act 1985 (Act 318) and National Land Code 1965 (Act 56) regarding 3D property, with a further 7 (6.6%) feeling very dissatisfied. Another 33 (31.1%) respondents found the situation acceptable while only 18 (17%) of the respondents either very satisfied or satisfied on this issue. It would seem that these two legal documents need further improvement. There was a strong group of 99 (93.4%) respondents that supported the development of a new legislation integrating 3D properties aspects while the remaining seven (6.6%) respondents either did not support or were not sure.

Figure 4c shows that only 12 (11.3%) of the respondents were very satisfied and 36 (34.0%) respondents were satisfied with the current legal institutions in enforcing the land law. Forty-four (41.5%) respondents felt there were sufficient legal institutions to enforce land law. Twelve (11.3%) respondents were dissatisfied and 2 (1.9%) very much so. It would appear, therefore, that the legal institutions needed to be further improved to enforce land law satisfactorily. On top of that, 68 (64.2%) respondents felt that the law should place responsibility for maintaining the 3D land register on a specific government authority while 25 (23.6%) respondents did not agree. In this connection, 86 (81.1%) respondents considered the land administration officials/surveyors sufficiently well versed in the existing land laws although 10 (9.4%) respondents disagreed and another 10 were not sure.

When asked whether Malaysia had a statutory system of land registration which recorded land rights, including ownership in a 3D environment, there was a significant group of 65 (61.3%) respondents that agreed whereas 29 (27.4%) respondents disagreed. Fifty (47.2%) out of 106 respondents agreed and 16 (15.1%) respondents strongly agreed that some of the buildings had been built on top of each other or crossed boundary edges in real estate developments. The remaining 25 (23.6%) stayed neutral and only 10 (9.4%) were in disagreement and another 5 (4.7%) in strong disagreement. It was generally felt that, there should be one, and only one, authority conferred with the authority to guarantee and authenticate land titles. There was concern that the security of tenures could otherwise be jeopardized. Accordingly, 82 (77.4%) respondents expected it to be easy to register properties in 3D with a single authority although 24 (22.6%) respondents thought it would be similarly easy with multiple authorities.

Malaysia has a statutory system of land registration which records rights in land, including ownership, in a public register in 3D environment. In real estate developments, some of the buildings have been built on top of each other or they cross boundary edges? The registration of properties in 3D environment is easy in multi authority or in single authority? There is a need for a legal registration status of 3D property. The existing law and guideline for stratum which under Part Five (A), Disposal of Underground Land, Section 92A to 92I, National Land Code 1965 can be used as a basis for 3D property volumetric land parcel alienation on and above the ground surface. 3D property legislation has an important role to play in achieving 3D property rights for Malaysia. It is compulsory for those obtaining 3D new rights in land to register those rights. What forms of land holdings should register in this new 3D environment. If leases are registered, what is the minimum term in years (how long) of a lease for it to qualify for registration? What, in your opinion, are the key problems with the current legislation that deal which 3D properties? What have been the key benefits and issues in the development and operation of the 3D property legislation?

Almost half of the respondents 43 (40.6%) and 44 (41.5%) either strongly agreed or agreed that it should be made compulsory for those obtaining 3D new rights in land to register those rights, whether on, above or below ground surface. At the same time, there were 17 (16%) who choose to stay uncommitted on this issue. There were another 2 (1.9%) respondents who disagreed. None strongly disagreed. A majority of the respondents, 69 (65.1%) out of 106, thought that the new 3D property should be registered as leasehold rather than freehold properties. If leases were registered, two thirds of the respondents, totalling 73 (68.9%) and 22 (20.8%) felt that the leases should run at least 60 or 99 years respctively to maintain the worth of the asset and for it to be easily transferable. Eleven (10.4%) respondents opined that the lease should only be 21 years.

Almost equal numbers of respondents (45 or 42.5% and 42 or 39.6%) strongly agreed or agreed respectively that there was a need for a legal registration status of 3D property. Fifteen (14.2%) respondents took a moderate stance and only a small number of respondent either disagreed or strongly disagreed. A great number of respondents, 74 (69.8%) either agreed or strongly agreed, opined that the existing law and guideline for stratum under Part Five (A), Disposal of Underground Land, Section 92A to 92I, National Land Code 1965 could be used as a basis for 3D property volumetric land parcel alienation on and above the ground surface. Twenty five (23.6%) respondents remained uncommitted on this issue. Altogether, 95 (89.6%) respondents responded that appropriate new legislation had an important role to play in achieving 3D property rights for Malaysia, with only four (3.8%) responding negative to the question while the remaining seven (6.6%) respondents were unsure on this matter.

Figure 3(e): Respond Rate for Land Administration (Question 30) Many of the respondents considered that a key problem with the current legislation that dealt which 3D properties lay with the legislators who were slow to take cognisance of, and respond to the need for changes that were essential for a better system of land registration and property management. Finally, the respondents felt that it would allow for a better quality of living in the urban centre, taking advantage of the services and facilities provided by local authorities, once the legislation on 3D environment was implemented.

Slightly more than half, 23 (51.1%), of the respondents felt that the current Cadastre Registration system was understood by surveyors and land administrators. However, nine (20.0%) respondents thought otherwise and 13 (28.9%) respondents chose to stay uncommitted on this issue. About half, 20 (44.4%) respondents strongly agreed and 15 (33.3%) respondents agreed that the main obstacle in adopting 3D cadastre was that the legal and organisational systems were slow to change and adapt. Eight (17.8%) respondents stayed neutral with two (4.4%) respondents strongly disagreeing.

Based on the analysis from the 45 returned questionnaire from DSMM and LLS responding to whether the legal system recognised the various 3D properties, 14 (31.1%) answered in the affirmative whereas nine (20%) disagreed. Nearly half (22 or 48.9%) the respondents skirted the issue. Thirty (66.7%) respondents thought that the traditional Cadastre System and land registry based on the 2D format had not been designed to cater for 3D property registration. Only 11 (24.4%) respondents felt that the current registry was adequate and 4 (8.9%) remained unsure. There were two-third, 30 (66.6%) of the respondents who either agreed or strongly agreed that the current Cadastre System was unable to handle the registration of 3D properties within the existing legislation. Small clusters of respondents disagreed and strongly disagreed respectively. Other than that, ten (22.2%) respondents stayed neutral on this issue.

Does the legal system recognise the various 3D properties? The traditional cadastre system and land registry that are based on 2D environment have been prepared to register property in 3D environment. The current cadastre system is not able to handle the registration of 3D property within the legislation. This current cadastre system is understood by surveyor and land administrator. The main obstacle in adopting cadastre in 3D environment is that the legal and organisational systems are slow to change.

The results of the survey also showed that more than half, 28 (62.2%) of the respondents considered surveying and mapping methods to be understood by surveyors and land administrators while slightly more the one-third, 17 (37.8%) respondents either disagreed or unsure. Out of 45 respondents, 26 (57.8%) respondents were of the opinion that all perimeter boundaries of the 3D property were identifiable. Nevertheless, 13 (28.9%) respondents thought otherwise, while the remaining 6 (13.3%) were unsure whether physical or virtual boundaries were identifiable (see Figure 5(c)).

Figure 5(a) and Figure 5(b) show that from the 45 returned questionnaire from DSMM and LLS, more than two-third, 37 (82.2%) of the total respondents either strongly agreed or agreed that DSMM should be responsible for maintaining the survey and mapping of registered 3D properties, whereas only 5 (11.1%) respondents were moderate in their view. Three (6.7%) respondents disagreed with it while none disagreed strongly. Concerning the suggestion that the Strata Lodgement Module, Electronic Strata Survey Module and Strata Verification Module had been the surveying and mapping methods that were used in the survey of 3D property, only slightly more than one-third, 16 (35.5%) indicated either they were satisfied or very satisfied with the statement.

Finally, many respondents felt that other relevant information on 3D properties and their regulation should be collated. Unlike the situation where the limits of the properties were only surveyed and indicated on plans, 3D geographical visualization methods could be employed to record many identifiable features as land users, facade, front, back, and side elevations, services, utilities, lamppost, traffic lights, even the roof, and the whole multitude can be captured and shown. The captured features and data would vary according to need.

I would like to express my sincere gratitude to my research supervisor Dr. Khadijah Binti Hussin for her remarks and corrections.

Specialists from many countries are studying the legal status of modern structures and properties with the objective to define and register these entities both legally and technically. Inconsistencies and irregularities that may crop up in future can be avoided by registering all real property objects, both under and above the ground surface, as 3D properties in the land registry. Accordingly, the legal and technical aspects of registering real property objects incorporating 3D methodologies in the Malaysian Cadastral System should be promulgated as a new field of research in both the legislative and technical frameworks. Research on 3D property rights and 3D cadastre is being carried out in several countries like the Netherlands and Sweden. The latter has been practising 3D property formation since 1st January 2004. From the present survey, the majority (57.5 %) of the respondents felt that the current land laws failed to define 3D property rights clearly. A large number (83.9%) of respondents thought that new legislation that integrated 3D aspects in cadastre registration, survey and mapping issues would address this anomaly. In this connection, government departments and agencies under various authorities are currently involved in preparing for the Cadastral System and Land Registration System in Malaysia. This is timely in view of the need for effective registration of 3D real properties and the improvement of the legal and technical regulations concerning 3D property rights.

Most traditional cadastral systems are based on two-dimensional (2D) registers that deal only with properties on the land surface. These systems are unsuitable for today’s multi-level reality. To cater to both above and below surface constructions and to enable the registration of real properties that are not limited to the land surface, it is necessary to amend the legislation. A threedimensional (3D) approach for Cadastral System and Land Registration System can provide a better means to manage our modern world. The existing Cadastral Systems do have a number of inherent advantages like responsibility for proprietary rights, up to date information coverage and good mapping (Benhamu and Doystsher, 2003). These advantages notwithstanding, they suffer from a number of weaknesses arising from their 2D limitations that result in their dealing only with properties on the land surface.
