This spatially-based information is typically used in allocation decisions, boundary definitions, planning processes and environmental monitoring, by internal and external stakeholders.
Automated, mathematical and statistical algorithms were applied against the TRIM I stream network and the TRIM I elevation surface model.

Object Name: WHSE_BASEMAPPING.FWA_WATERSHED_GROUPS_POLY
Short Name: FWWTRSHDGR
Comments: Contains polygons delimiting the watershed group boundary which is a collection of drainage area basins. In-land groups will contain a single polygon, coastal groups may contain multiple polygons (one for each island) i.e., this is a multipart polygon feature. Spatial geometry: multipart polygon
|Column Name||Short Name||Data Type||Data Precision||Comments|
