Object Description


Short Name: CWB_CRPHOL
Comments: The TRIM Watershed Atlas (TWA) delineation algorithms define the CORPORATE HEIGHTS OF LAND with optimal accuracy, the watershed boundaries and catchment regions for all hydrological features of the Terrain Resource Information Management dataset for British Columbia.

Column Name Short Name Data Type Data Precision Comments
CORP_HEIGHT_OF_LAND_SEGMENT_ID CRP_HL_SID NUMBER 10 A mutable unique identifier for a corporate height of land segment which serves as the primary key for the spatial layer.
CORP_HEIGHT_OF_LAND_FEATURE_ID CRP_HL_FID VARCHAR2 30 The CORP HEIGHT OF LAND FEATURE ID is a text string that serves as a unique identifier for a given bounding segment in theCorporate HOL database.
FEATURE_CODE FEAT_CODE VARCHAR2 10 The MOEP standard numeric code to identify the type of feature represented by the spatial data.
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.
