Florida Marine Tracks: Mapping Florida’s Waterways Marc D. Marino, GIS Specialist Alexander E. Rivas, GIS Specialist Glenn D. Housman, President/Owner
What is Florida Marine Tracks? • Marine Cartographic Design Company • Produce Electronic Charts for Marine Navigation • We are Global Mapper Users
What is Florida Marine Tracks? • Users navigate depths of 3 feet or less • Higher risk for boating accidents
Impact on Coastal Ecosystems • Increasing amount of boating accidents. • Negatively impacting ecosystem
Current Navigation Aids in Use • Non-Electronic Aids 1. Paper Maps 2. Channel Markers
•
Electronic Aids
Marine Navigation Units • Electronic Aids • Easy to use
• Marine navigation units offer a safer boating experience.
FMT: Current Area of Interest • Began in 2006 with coverage of the Florida Keys only.
• Now includes state-wide coverage.
Coverage Area • Florida’s Coastline • The longest saltwater coastline of any state in the contiguous U.S. (approximately 1,350 miles long) • West Coast: Approximately 1,300 miles • Large dataset
Coverage Area • Florida Keys and Florida Bay. • No other company incorporates Florida Bay in their maps. • Originally a KML file recorded on a HDS Marine Navigation Unit.
Coverage Area • Inland Rivers, Lakes, and Intracoastal Waterways • FMT only company to provide routes for this area
FMT: Project and GIS Requirements • Need for efficiency. • 100,000+ aerial photos in FMT Database
FMT: Aerial Photo Display and Organization • Map Catalog Creation and Editing • Aerial photos in various projections
Global Mapper: Attribute Calculation • Depth Soundings • Field attributes needed for feature display
• Conversion from meters to feet
Global Mapper: Attribute Analysis • Attribute values are frequently edited and updated.
Global Mapper: “Tracks” and Routes • Global Mapper attribute calculator allows the tracks to be read by the HDS unit.
Global Mapper: Basemap Production
FMT: Redefining Marine Cartography • Enhanced aerial photography combined with area specific bathymetry and routes.
Global Mapper: Photo and Imagery Acquisition • Aerial photography acquired from the Florida Department of Transportation
• Counties updated annually
FMT: Imagery Enhancements • Brightness and contrast adjustments to offset outdoor environment • Mosaic and area clip can be accomplished using digitizer tools
Contour Calculation • Global Mapper, Generate Contour From Terrain Grid Tool • Open source DEM provided by NOAA
Contour Calculation • Global Mapper, Show 3D Function
FMT: Basemap Results • 6-inch resolution aerial coverage overlay. • Complete coverage of Florida at 1 foot resolution.
Basemap Results • Global Mapper, Water Level Function
Basemap Results • High resolution coverage • Customized raster and vector data
SDHC Formatting • Navico toolbox is utilized to convert all shapefiles, photos, and imagery to Atlas5 files. • Files are read by Lowrance HDS Unit based on attributes fields created in Global Mapper.
SDHC Formatting • Maximum capacity of 32g. • High resolution photography only displayed over water.
Conclusion • Global Mapper Functionality Employed by FMT: 1. Vector attribute calculation and editing.
2. Image mosaic and clip of all FMT photography. 3. Elevation contour creation from a DEM. 4. Raster Map Catalog creation of Florida DOT photography. 5. Raster file format conversion .
Comments and Questions • Thank you and happy boating from the FMT team!
