THE DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED AS LEGALLY BINDING. THE UNIVERSITY OF FLORIDA GEOPLAN CENTER SHALL NOT BE LIABLE FOR ANY DAMAGES SUFFERED AS A RESULT OF USING, MODIFYING, CONTRIBUTING OR DISTRIBUTING THE MATERIALS. A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.

This GIS data layer was generated by the Florida Natural Areas Inventory (FNAI) using ArcView v 3.2 and ArcGIS-ArcInfo 9.1. Source polygons were developed from the BIOTICS ArcView application. The polygons were imported into an ArcInfo region using ArcInfo 9.1. Overlaps less than 0.002 meters were removed using the ArcInfo CLEAN command. The ArcInfo region was then converted into a polygon shapefile using ArcMap 9.1. Information in the FLMA data layer was provided to FNAI by the individual managing agencies. Boundary information on managed areas was originally in either digital format or on paper source maps with varying scales. New digital boundary files were integrated into FLMA by FNAI staff. In the case of paper source maps, boundaries were either transcribed by FNAI staff onto 1:24,000 USGS topographic quadrangles and then digitized, or boundaries from paper maps were transcribed by FNAI staff in ArcView or ArcMap using underlying USGS 1:24,000 DRG and/or 2004 DOQQs and on-screen digitization methods. FNAI staff then integrated these new digital boundaries into FLMA. The attribute item DIG_COM in the FLMA layer provides details on the derivation of boundaries for individual managed areas. The following digitizers were used by the FNAI staff: CalComp DBII, accuracy of +/- .01 inch CalComp DBIII, accuracy of +/- .005 inch CalComp 9500 Series, accuracy of +/- .005 inch When digital boundaries from one source overlapped with digital boundaries from another source, the boundaries were adjusted by FNAI staff to eliminate the overlapping areas. Adjustments were made based on the best known information about the source of the boundaries. All overlaps greater than 0.002 meters were removed using this process. Process Date: Unknown |
