Object Description

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
WATERSHED_GROUP_ID WTRSHDGRPD NUMBER 18 An automatically generate id that uniquely identifies the watershed group feature.
WATERSHED_GROUP_CODE WTRSHDGRPC VARCHAR2 4 The four character watershed group code, e.g. ADMS (Adams River), ALBN (Alberni Inlet).
WATERSHED_GROUP_NAME WTRSHDGRPN VARCHAR2 80 The name of the watershed group.
AREA_HA AREA_HA NUMBER 38 The area of the polygon in hectares.
FEATURE_CODE FTRCD VARCHAR2 10 FEATURE CODE contains a value based on the Canadian Council of Surveys and Mapping's (CCSM) system for classification of geographic features.
GEOMETRY GEOMETRY SDO_GEOMETRY 1 GEOMETRY is the column used to reference the spatial coordinates defining the feature.
OBJECTID OBJECTID NUMBER 38 OBJECTID is a required attribute of feature classes and object classes in a geodatabase.
SE_ANNO_CAD_DATA BLOB 4000 SE_ANNO_CAD_DATA is a binary column used by spatial tools to store annotation, curve features and CAD data when using the SDO_GEOMETRY storage data type.
FEATURE_AREA_SQM NUMBER 19 FEATURE_AREA_SQM is the system calculated area of a two-dimensional polygon in square meters
FEATURE_LENGTH_M NUMBER 19 FEATURE_LENGTH_M is the system calculated length or perimeter of a geometry in meters
