Codes (Y/N) |
| EDASUBEDA | 5-digit Watershed Code | Char 5 | N |
A code assigned to each derived spatial area (e.g., an EDA or CDA). Concatenated from the EDACDA attribute and SUBEDA attribute from NOAA's Coastal Assessment Framework | Y |
|
| SUB_NAME | Watershed Name | Char 55 | N |
For EDAs with component sub-major watershed drainages (subEDAs) defined (e.g., the Chesapeake Bay), a subEDA specific name | N |
|
| EDACODE | 4-digit Major Watershed Code | Char 4 | N |
A code assigned to each major watershed area (e.g., an Estuarine Drainage Area, Coastal Drainage Area, Fluvial Drainage Area, Interior Drainage Area, etc.). | Y |
|
| EDA_NAME | Major Watershed Name | Char 50 | N |
A geographic name associated with each major watershed area. Names of EDAs come from NOAA’s National Estuarine Inventory; names of CDAs are a combination of edacda code plus USGS cataloging unit name. Unique Names have corresponding EDACDA Codes. | N |
|
| REGION | Region Code | Char 1 | N |
NOAA Coastal Assessment Region; (N = North Atlantic, M = Mid-Atlantic, S = South Atlantic, G = Gulf of Mexico, P = Pacific, L = Great Lakes, U = Interior, X = International | Y |
