FDEP provided the January 2003 shapefile. ArcInfo COGO was used whenever bearing and distance calls or northing and easting points where available. After completion of thorough research to assure the use of the most accurate source, legal descriptions and property deeds were interpreted and COGOed and/or digitized into an ArcInfo coverage. FDEP based creation of the FSP (Florida state parks) coverage on a projected USGS quad boundary coverage in State Plane. Once the coverage was completed, CLEANed and edited, it was projected to NAD-83. FDEP used ArcView to relate attribute information to their GIS data set.
FDEP derived information from BTIITF leases, deeds, surveys, plats, or1:24,000 quads.
