TITLE: PRIME FARMLAND IN FLORIDA WITH ASSOCIATED LEVEL 3 WATER MANAGEMENT DISTRICT LAND USE DESCRIPTIONS

Geodataset Name:       PRIMEFARM_LU
Geodataset Type:       SHAPEFILE
Geodataset Feature:    Polygon
Feature Count:         92474
GENERAL DESCRIPTION:
This data set represents level 3 agricultural water management district land use that falls within areas that have been identified by the NRCS as prime farmland (or farmland of unique or local importance). During the process all areas less than .25 acres were removed. The following 5 water management district land use layers were used: LU_SWFWMD_2011, LU_SJRWMD_2009, LU_SFWMD_2008, LU_SRWMD_2011, LU_NWFWMD_2010. The farmland classification was taken from the spatial view based on NRCS_SOILS_JUN12.

FRMLNDCL Farmland Classification: Identification of map units as prime farmland, farmland of statewide importance, or farmland of local importance.

SOURCE Water Management District of Coverage/Origin.

LEVEL1 Level 1 land use description, based on the FDOT classification schema.

FLUCCS_L2 The second highest level (level 2) designation in a hierarchical coding scheme containing 4 levels.

LEVEL2 Level 2 land use description, based on the FDOT classification schema.

FLUCCS_L3 The third highest level (level 3) designation in a hierarchical coding scheme containing 4 levels.

LEVEL3 Level 3 land use description, based on the FDOT classification schema. There is a possibility that the FDOT Level 3 description does not match that of the Water Management District, for those occurrences this discrepancy has been identified in the FLUCCSCOMP field.

ACRES Number of Acres.

DESCRIPT Based on combination of shortened text from NRCS soils field = FRMLNDCL and Level 3 water management district land use descriptions.

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

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:
Created WMD layer 
-----------------
Used the following WMD layers, in order of priority:
  LU_SWFWMD_2011
  LU_SJRWMD_2009
  LU_SFWMD_2008
  LU_SRWMD_2011
  LU_NWFWMD_2010
Selected only areas that intersected SV_PRIMEFARMLAND
Merged features
Dissolved

Created farmland layer
---------------------------
export SV_PRIMEFARM (spatial view) to feature class.
note: spatial view is based on NRCS_SOILS_JUN12 and is created using the following query:
FRMLNDCL = 'ALL AREAS ARE PRIME FARMLAND' OR 
FRMLNDCL = 'PRIME FARMLAND IF DRAINED AND EITHER PROTECTED FROM FLOODING OR NOT FREQUENTLY FLOODED DURING THE GROWING SEASON' OR 
FRMLNDCL = 'PRIME FARMLAND IF DRAINED' OR 
FRMLNDCL = 'FARMLAND OF LOCAL IMPORTANCE' OR 
FRMLNDCL = 'FARMLAND OF UNIQUE IMPORTANCE'

Overlay of farmland and land use
--------------------------------
Select out level 1 = agriculture lands
Ran identify command using farmland as input layer and WMD layer as overlay layer
Repair geometry
