USER NOTES:
This data is provided 'as is'. GeoPlan relied on the integrity
of the original data layer's topology
This data is provided 'as is' by GeoPlan and is complete to our
knowledge.
GeoPlan relied on the integrity of the attribute information within
the original data.

The data was created to serve as base information for use in GIS systems 
for a variety of planning and analytical purposes.

This data is provided 'as is' and its horizontal positional accuracy
has not been verified by GeoPlan

This data is provided 'as is' and its vertical positional accuracy
has not been verified by GeoPlan

Each Water Management District has its own data disclaimer, for this 
information and more information about each WMD, please visit their 
website.

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. The University of Florida GeoPlan Center
makes no representations or warranties about the quality or suitability
of the materials, either expressly or implied, including but not limited
to any implied warranties of merchantability, fitness for a particular

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. For more information regarding
scale and accuracy, see our webpage at:

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_2013
LU_SFWMD_2008
LU_SJRWMD_2009_FEB12
LU_SRWMD_2011
LU_SWFWMD_2011

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_MAY13.shp was cleaned up 
using the following techniques.

1. The layer was the converted from multipart to single part.
2. Ran Repair Geometry 3x.
3. Ran Integrate command at 1m.
4. Ran Repair Geometry 3x.
5. 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].
6.  A selection was made where TEST < 0.1
    The Eliminate command was then run on this selection set
7. Slivers that were not absorbed via the Eliminate command were later deleted.
8. Ran Repair Geometry 3x.
7. Updated the ACRES field.
