FEATURE ATTRIBUTE TABLES CODES AND VALUES:
ITEM DESCRIPTION/VALUES
MSYM Symbol that corresponds to divisions on the source map.
SECTION Code for the primary, or largest, physiographic division.
ATL = Atlantic Coastal Plain Section
FLO = Florida Section
GUL = Gulf Coastal Plain Section
DISTRICT Name of the district or secondary physiographic division.
PROVINCE Name of the province or tertiary physiographic division.
Also, referred to as "subdistrict" in source text.
SUBPROVINC Name of the subprovince or quaternary physiographic
division.
NAME Name equivalent to the the province or subprovince,
whichever is the smallest physiographic division named
for an area.
CODE Code that combines SECTION and MAPSYM and is a means to
reference descriptions in the source text. It is in the
form SECDPS, where SEC = SECTION, D = DCODE, P = PCODE,
S = SPCODE.
DCODE District code.
PCODE Province code.
SPCODE Subprovince code.
DESCRIPT Item added for FGDL; Based on NAME item.
USER NOTES:
Please note the original data is in regions, therefore this data layer is made of both lines and polygons.
Fairly detailed descriptions for each physiographic division are given in "The Guide to Physiographic Divisions of Florida." Descriptions include information about elevation, geology, soils, and vegetation.
FGDL QUALITY ASSURANCE STATUS:
-Coverage was Projected from UTM Zone 17 to FGDL Albers.
-Tolerances were set to FGDL standards.
-All attribute records were converted to uppercase format.
-DESCRIPT itembased on type.

DATA LINEAGE SUMMARY:
The source map was developed in 1981 on a 1:500:000 scale basemap provided by
U.S. Geological Survey.
The Physiographic Regions layer was developed in two stages. At first,
only the area within St. Johns River Water Management District was digitized
sometime before October 1995. Then in December 1997, the rest of the
features on the map were added to the data layer. Initial arc features
possess a VERSION value of 1, while secondary arc features possess a VERSION
value of 2.
Spatial accuracy is questionable with this data layer and should be assessed
before the layer is determined to be an appropriate component for a
particular analysis. This problem is due to the condition of the source
document, the two-step development process.
The original dataset existed in UTM, Zone 17, NAD 1983, 1990 Adjustment.
