The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist. Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources.

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.

DATA LINEAGE SUMMARY:

The following Water Management District Land Use/ Land Cover data sets were used in the creation of the data layer. LU_NWFWMD_2010 LU_SFWMD_2008 LU_SJRWMD_2009_FEB12 LU_SRWMD_2008 LU_SWFWMD_2009 The following query was run against the five WMD Land Use/ Land Cover data sets in order to create five subset layers. [FLUCCS_L1] = 2000 Next the five WMD subset layers were combined to create one statewide layer. Finally the newly created AGRICULTURE_APR10.shp was cleaned up using the following techniques. 1. The layer was the converted from multipart to single part. 2. The following fields were created and updated ACRES, AREA, LENG, SLIVER, and TEST. The following calculation was used to populate the SLIVER field: 4 * (( 3.14 * [area] ) / ( [leng] * [leng] )) The TEST field was calculated using the equation [ACRES] * [SLIVER]. 3. A selection was made where TEST < 0.1 The Eliminate command was then run on this selection set 4. Slivers that were not absorbed via the Eliminate command were later deleted. 5. The layer was imported to a File Geodatabase where the topology was validated at a cluster tolerance of 1m and gaps were not allowed. 6. The layer was then exported to shapefile and the geometry was then cleaned. 7. Finally the repair geometry function was run once more and the ACRES field was updated. Process Date: 20121127
