|Column Name||Short Name||Data Type||Data Precision||Comments|
|GRID_ID||GRID_ID||VARCHAR2||11||GRID ID is the unique identifier for the polygon and is a combination of the mapsheet id and the group id. This is a user maintained primary key. e.g., 082E03|
|MAP_SHEET_ID||MAPSHEET||VARCHAR2||4||MAP_SHEET_ID is similar to the naming of the 1:250,000 NTS maps sheets. e.g., 082E|
|GROUP_ID||GROUP_ID||VARCHAR2||2||GROUP_ID is the last 2 character of the 1:50,000 NTS map sheet which it approximates. e.g., 03 for NTS sheet 082E03|
|UTM_ZONE||UTM_ZONE||VARCHAR2||2||UTM_ZONE is a segment of the Earth's surface 6 degrees of longitude in width. The zones are numbered eastward starting at the meridian 180 degrees from the prime meridian at Greenwich. There are five zones numbered 7 through 11 that cover British Columbia, e.g., Zone 10 with a central meridian at -123 degrees.|
|LABEL||LABEL||VARCHAR2||15||LABEL is the recommended label for mapping and presentation. e.g., 082E|
|FEATURE_CODE||F_CODE||VARCHAR2||10||FEATURE CODE contains a value based on the Canadian Council of Surveys and Mapping’s (CCSM) system for classification of geographic features. e.g., AR82000110|
|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|
