This linear dataset includes rivers in British Columbia, suitable for mapping and analysis at the 1:1 million scale.

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

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

Previously, this dataset was called WHSE_IMAGERY_AND_BASE_MAPS.DRP_RIVERS_1M_SP. At that time, it included the coastline, lake and double line river outlines. This version of the data does not include those features; it only includes single line river features. The coastline is depicted in the "Political Boundaries" dataset and the lakes and wide rivers are depicted as polygons in the "Waterbodies" dataset. See above description for links to those datasets.

Object Description

Object Name: WHSE_BASEMAPPING.NRC_RIVERS_1M_SP

Short Name: RIVERS_1M
Comments: Rivers published by Natural Resources Canada under the Atlas of Canada, 1:1,000,000 National Frameworks Data. Features represent single line streams; wide rivers are modelled in the Waterbodies 1:1 Million Atlas of Canada layer. This datase

Column Name Short Name Data Type Data Precision Comments
NRC_RV1M_SYSID RV1M_ID NUMBER 10 NRC_RV1M_SYSID is a system generated unique identification number.
TYPE TYPE VARCHAR2 50 TYPE describes the type of river, i.e., River, Intermittent River, Underground Water Connection.
SELECTION SELECTION VARCHAR2 20 SELECTION is a descriptive cartographic field used to display only major rivers (sparse), or to include smaller streams (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.
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 river. A null value indicates the segment is not named or the name is not known.
NOM NOM VARCHAR2 100 NOM is the name, in French, of the river. A null value indicates the segments is not named or the name is not known.
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 ANNO_CAD 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.
