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.

Brownfields: <http://www.dep.state.fl.us/waste/categories/brownfields/default.htm>
Boundaries from paper maps were digitized over the 1994-1995 DOQQs with various other existing layers for reference, such as TIGER Roads, USGS Railroads (24k), and FDOT Local Roads, using ArcView 3.2a
ArcView shapefiles were reprojected and imported into the base polygon shapefile.
Where shapefiles and paper maps were not available, legal descriptions were used to create the boundaries using COGO (Coordinate Geometry) in ArcInfo 8.0.2
Locational quality information was maintained throughout data development by recording the USERNAME, DATESTAMP, and SOURCE for each feature. See METHOD field to determine which process was used to develop each feature.
Graphics and attributes of the original 44 Brownfields current at the time of data development were visually verified by Camisha Clarke and Carl Eichenberger and independently QCd by Patrick Pence.
Finally, useful fields from the original database were joined to the polygons.
10/31/01 A seventh Ocala Brownfield area was added by screen digitizing.
- Added DESCRIPT item based on the AREANAME field - Added field FGDLAQDATE based on date downloaded from source - Upcased on fields in the table.
