These data are designed to provide a guidance and a general proximity of the locations of Special Flood Hazard Areas(SFHA) and zones of possible risks associated with food inundation. In addition to locational and topological information, features contained in the data set include 1%(100 year) and 0.2% (500 year) annual chance flood plain boundaries, flood insurance zone designations (including Velocity zones), flood way boundaries(when available), political boundaries(State, county and community), community and map panel identification number, FIRM panel neat lines, USGS 7.5-minute (1:24,000 scale) topographic map quadrangle neat lines, and Coastal Barrier Resource Act(COBRA) areas. unknown publication date Complete As needed -87.639410 -79.872549 31.042833 24.456926 None water FEDERAL EMERGENCY MANAGEMENT AGENCY land use Flood insurance rates Flood plain Planning ISO 19115 Topic Categories planningCadastre None Florida FLood insured Lands None 1990's None 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.

Certain node/geometry and topology (GT)-polygon/chain relationships are collected or generated to satisfy topological requirements. Some of these requirements include: chains must begin and end at nodes, chains must connect to each other at nodes, chains do not extend through nodes, left and right GT-polygons are defined for each chain element and are consistent throughout the transfer, and the chains representing the limits of the file (neatline) are free of gaps. The neatline is generated by connecting the four corners of the digital file, as established during initialization of the digital file. All data outside the enclosed region are ignored and all data crossing these geographically straight lines are clipped at the neatline. (Exception: During the QA/QC process all data is examined and if errors are found and corrections are possible, then data is corrected accordingly. This process is documented in the Process_Step.) Data within a specified tolerance of the neatline are snapped to the neatline. Neatline straightening aligns the digitized edges of the digital data with the generated neatline, that is, with the longitude/latitude lines in geographic coordinates. All internal polygons are tested for closure. Certain attributes and/or entities, e.g. closure line, convey data quality information. When information to be encoded in the subfield is known to be not applicable (undefined, not relevant), then the subfield is valued by a string of "9s"; and when the information to be encoded is relevant but unknown (or missing), then the subfield is valued by a string of "9s."

The originating agencies created the original spatial coverage. GeoPlan, during the QA/QC process included the following aspects: (1) Reprojected data to FGDL Albers (2) Set Precision to DOUBLE (3) Set Tolerances to FGDL Standards (4) Added DESCRIPT based on ZONE GeoPlan unknown For 10 of the counties that were missing (BRADFORD, COLUMBIA, DIXIE, GILCHRIST, HAMILTON, JEFFERSON, LAFAYETTE, MADISON, TAYLOR, UNION) a countywide polygon was appended and the DESCRIPT was calculated to "NO DATA AVAILABLE". Note that OKEECHOBEE County already had a polygon covering the county which didn't have any FEMA information in it. This polygon was also calculated with "NO DATA AVAILABLE". There were several records that had ZONE = ''. In these cases the DESCRIPT was calculated to "NO DESCRIPT AVAILABLE".
