Lytle Creek Watershed Interactive Map Project By: Brandon Sierra Academic Adviser: Dr. David Turner Director of WRI: Susan Longville HSI Program Manager Principle Investigator: HSI Dr. Jim Noblet HSI Internship Coordinator: Lisa Pierce 6/19/2009
Lytle Creek Project Background • Lytle Creek watershed is located in the San Bernardino Mountains, accessible from Route 15 in the Cajon Pass. Lytle Creek is a major source of drinking water for our region and serves the communities that obtain their water from West Valley Water District, Fontana Water Company and San Bernardino Valley Municipal Water District.
Lytle Cr
These were the first four sample sites
The Project • The goal of the Lytle Is Vital project was to allow public users the ability to see the measure of different contamination constituents in the Lytle Creek Watershed. • The data was then to be served to the internet and displayed in a column chart that is more appealing to public users. • The two samples taken were of E‐Coli and Enterococcus • Sample period has so far been about 1 year, from May 2008 – April 2009, and may continue into the future
The Project Contd. • One of the goals was to make the column chart to query the data from the map so that as more data is added over time, the graph will automatically update itself to include the new data.
Database Issues • One of the biggest challenges was having to manage a very complex data set that needed to include many dates for two constituents and multiple sites • This required normalizing our database in a very unique way. This required ESRI help to fit our 3‐Dimensional science data into their 2‐Dimensional database design
Project Process • I started out going about my task using ESRI’s products ArcGIS Desktop 9.2 and ArcGIS Server 9.2 with the .NET Framework. • After much research and visiting some different websites that we offered by ESRI as well as talking with an ESRI Instructor for ArcGIS Server, I found out that my task could not be accomplished using the 9.2 edition of ESRI’s products.
Project Process Contd. • I was convinced to upgrade to the newest version of ESRI’s software, ArcGIS Desktop 9.3 and ArcGIS Server 9.3. • The main advantage of version 9.3 over 9.2 was that there are more Web Applications development that are supported for the updated software. • For 9.2, there were only two Web Applications that were supported, .NET and Java. • For 9.3, in addition to .NET and Java, JavaScript, Flex, and Silverlight (Beta) are also supported.
1. The first goal was to install all of the newer software products from ESRI, along with download Adobe Flex Builder 3 and the Flex API libraries that were available on http://resources.esri.com/arcgisserver/apis/flex/ 2. Next we had to migrate the maps we were using from ArcGIS Desktop 9.2 to 9.3 3. After that, I had to create a map service of the map using ArcGIS Server 9.3
4. The 9.3 edition had a new built in function that would allow me to easily look up the URL of my map service to add as a layer into the Flex Builder 5. The ArcGIS Server Instructor from ESRI that was helping us gave me a project that was similar to my goal, so I needed to learn enough of the ActionScript and mxml languages to alter the code given to me.
7. Once the database was designed, the code was altered and the flash file was created. 8. Next I had to develop a webpage to describe the project, have links to my internship application, abstract, project report, and a link to the Lytle Creek Interactive Map
Main Issues • Installing ArcGIS Servicer on the server – Security lockdown on the server forced us to change the External IP address from a hard coded address to an Unassigned address and that allowed the Services to be created correctly in the D drive
