FEATURE ATTRIBUTE TABLES CODES AND VALUES:
ITEM ITEM DESCRIPTION
SHAPE Data attribute inherent to the ESRI shapefile format,
which defines the data as a point, polyline, or polygon.
OLD_UNIQUE Historic CAF 'Unique' Polygon Code prior to this update
UNIQUE A unique integer assigned to every spatial area in the Coastal
Assessment Framework. Every EDA or CDA has a unique number;
islands within an EDA or CDA are assigned that EDAs or CDAs
unique number.
CAF_UNIQUE A consistently derived code concatenated from EDA_SUBEDA,
USGS_HHUC and P_TYPE - see below for definitions of these.
EDACDA A code assigned to each major watershed area (e.g., an Estuarine
Drainage Area, Coastal Drainage Area, Fluvial Drainage Area,
Interior Drainage Area, etc.).
NAME A geographic name associated with each major watershed area. Names
of EDAs come from NOAAs National Estuarine Inventory; names of
CDAs are a combination of edacda code plus USGS cataloging unit
name. Unique Names have corresponding EDACDA Codes.
CAF_LGND A text string that describes, for a legend, the spatial area.
Essentially this name collapses the variety of Coastal Drainage
Areas names from SUBNAME to a singular 'Coastal Drainge Area'
label.
SUB_NAME For EDAs with component sub-major watershed drainages (subEDAs)
defined (e.g., the Chesapeake Bay), a subEDA specific name.

attribute).

Fluvial Drainage Area - Area is a Fluvial Drainage Area
Freshwater portion of an EDA - Area is a Freshwater portion of an EDA
Great Lake or St Lawrence River CDA - Area is a Great Lake or St Lawrence RiverCDA

Water - Area is Water based (POLYTYPE = 2)
SUBEDA Alphabetical code indicating polygon is a subEDA.
a - t Identifies individual subEDAs found in estuaries where subEDAs have
been defined (e.g., Chesapeake Bay). Only EDAs have subEDAs.
w Identifies those polygons in an EDA not already assigned to a subEDA.
The reamining core of the major EDACDA Watershed. Applies only to EDAs
that have subEDAs.
x All other polygons. These include all major watersheds (EDAs) that do
not have SubEDAs.
UNIQUE_ID A unique character string assigned to every spatial area in the
Coastal Assessment Framework. Composed of a concatenation of each
polygon's EDACDA code and its polygon type (e.g., Estuarine
Drainage Area, Coastal Drainage Area, Fluvial Drainage Area, etc.).
OLDCAF Historic EDASUBEDA Code prior to this update.
CLASS Polygon classification Code.

St. Lawrence River, or an ocean (self-contained drainage).

USER NOTES:
The Coastal Assessment Framework (CAF) is a digital spatial framework developed using geographic information system technology, which allows resource managers and analysts to organize and present information on the nation's coastal and marine resources. The CAF provides a consistently derived, watershed-based digital spatial framework for managers and analysts to organize and present information on the nation's coastal, near-ocean, and Great Lakes' resources. Within NOAA, it is the cornerstone of a series of ongoing efforts to develop a national estuarine assessment capability. Nation wide the framework is composed of 150 Estuarine (and sub-estuarine) Drainage Areas EDAs), 54 Fluvial Drainage Areas (FDAs), 324 Coastal Drainage Areas (CDAs), 12 Fluvial components of Coastal Drainage Areas (FCDAs), 11 interior watershed areas (self-contained, Grounwater-contributing only, or watersheds draining to outside the U.S.). The CAF encompasses 100 percent of the land area within the coterminous United States of America. Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modelling 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. 1:250000 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 analyses. 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 web pages at: http://www.geoplan.ufl.edu/education.html

DATA LINEAGE SUMMARY:
This dataset was downloaded in shapefile format from the NOAA Special Project Office website (http://cammp.nos.noaa.gov/spo/prodlist.taf?alltype=3). When received, the data was in Geographic projection, Datum: NAD83, Spheroid: GRS1980, Units: Decimal degrees. The shapefile was clipped to the Florida State boundary and projected to FGDL Albers HPGN (See "Map Projection Parameters" below).
