The polygons in this dataset represent the terrestrial land base of British Columbia, suitable for mapping and analysis at the 1:1 million scale. Features are single part polygons; each island has its own record.

The Atlas of Canada National Scale Data 1:1,000,000 Series consists of a number of data sets that were compiled to be used for atlas large scale (1:1,000,000 to 1:4,000,000) mapping. These data sets have been integrated so that their relative positions are cartographically correct.

This dataset contains information licensed under the Open Government Licence – Canada. The British Columbia portion of the nationwide dataset was extracted for publication to the BCGW.

Additional Information


The Atlas of Canada 1:1,000,000 National Scale Data are a set of integrated base map layers. These data have been compiled at a scale of 1:1,000,000 with the primary goal being to indicate correct relative positioning with other frameworks layers rather than absolute positional accuracy.

Object Description


Short Name: POL_BND_1M
Comments: Political Boundaries published by Natural Resources Canada under the Atlas of Canada, 1:1,000,000 National Frameworks Data. This dataset contains singlepart polygon features representing the mainland and the coastal islands of British Colum

Column Name Short Name Data Type Data Precision Comments
NRC_PB1M_SYSID PB1M_ID NUMBER 10 NRC_PB1M_SYSID is a system generated unique identification number.
SELECTION SELECTION VARCHAR2 20 SELECTION is a descriptive cartographic field used to display only the mainland and larger islands (sparse) or to include the smaller islands (dense). On a small scale map showing a significant portion of the province, including only features categorized with a sparse selection would be suitable, whereas a larger scale map may include features categorized as both sparse and dense.
FEATURE_AREA_SQM AREA_SQM 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.
SHAPE SHAPE SDO_GEOMETRY 1 SHAPE is the column used to reference the spatial coordinates defining the feature.
OBJECTID OBJECTID NUMBER 38 OBJECTID is a column required by spatial layers that interact with ESRI ArcSDE. It is populated with unique values automatically by SDE.
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.
