Object Description

Object Name: WHSE_WATER_MANAGEMENT.SSL_SNOW_SURVEY_BASIN_AREA_SP

Short Name: SSL_SSB_SP
Comments: Snow survey administrative basin areas are a multipart polygon layer. The Accuracy is 200 metres in defineable areas. Flatter areas are less accurate. The polygons were digitized by Hydrology Branch 1994.

Column Name Short Name Data Type Data Precision Comments
BASIN_ID BASIN_ID VARCHAR2 7 User Assigned Primary unique identifier for a feature.
FEATURE_CODE FEAT_CODE VARCHAR2 10 A standard numeric code to identify the type of feature represented by the spatial data. A feature code is most importantly a means of linking a feature to its name and definition. For example, the code GB15300120 on a digital geographic feature links it to the name "Lake - Dry" with the definition "A lake bed from which all water has drained or evaporated." The feature code does NOT mark when it was digitized, what dataset it belongs to, how accurate it is, what it should look like when plotted, or who is responsible for updating it. It only says what it represents in the real world. It also doesn't even matter how the lake is represented. If it is a very small lake, it may be stored as a point feature. If it is large enough to have a shape at the scale of data capture, it may be stored as an outline, or a closed polygon. The same feature code still links it to the same definition.
BASIN_NAME BASIN_NAME VARCHAR2 20 User Assigned Basin unique name.
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 FEAT_AREA NUMBER 19 FEATURE_AREA_SQM is the system calculated area of a two-dimensional polygon in square meters
FEATURE_LENGTH_M FEAT_LEN NUMBER 19 FEATURE_LENGTH_M is the system calculated length or perimeter of a geometry in meters
