This polygonal dataset contains fresh water lakes and rivers in British Columbia, suitable for mapping and analysis at the 1:1 million scale. It does not include the coastline; a feature that was previously included in 1:1 million lakes and rivers datasets. The coastline is included in the Atlas of Canada 1:1,000,000 National Scale Data - Political Boundaries dataset.

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. Islands within waterbodies were clipped out of the waterbodies.

Additional Information

Purpose

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.

Lineage Statement

The previous version of this dataset was WHSE_IMAGERY_AND_BASE_MAPS.DRP_LAKES_1M_SP. It contained coastal island polygons. This dataset does not contain coastal islands.

Object Description

Object Name: WHSE_BASEMAPPING.NRC_WATERBODIES_1M_SP

Short Name: WTRBOD_1M
Comments: Fresh Waterbodies published by Natural Resources Canada under the Atlas of Canada, 1:1,000,000 National Frameworks Data. Features represent lakes and wide rivers. Single line rivers are modelled in the Rivers 1:1 Million Atlas of Canada lay

Column Name Short Name Data Type Data Precision Comments
NRC_WB1M_SYSID W1M_ID NUMBER 10 NRC_WB1M_SYSID is a system generated unique identification number.
TYPE TYPE VARCHAR2 50 TYPE describes the type of waterbody, i.e., Intermittent Water, Permanent Water.
SELECTION SELECTION VARCHAR2 20 SELECTION is a descriptive cartographic field used to display only major waterbodies (sparse) or to include smaller waterbodies (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.
RESERVOIR RESERVOIR VARCHAR2 10 RESERVOIR indicates weather the feature is a water resevoir, i.e., yes, no, unknown.
CGNS CGNS VARCHAR2 32 CGNS is the national identifier for the feature. This is a UUID (Universal Unique Identifier) represented by a 32-character hexadecimal string, e.g., ffae101dd05311d892e2080020a0f4c9
NAME NAME VARCHAR2 100 NAME is the name, in English, of the waterbody. A null values indicates the waterbody is not named or the name is not known.
NOM NOM VARCHAR2 100 NOM is the name, in French, of the waterbody. A null values indicates the waterbody is not named or the name is not known.
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.
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.
