Points with rotations that indicate downstream flow direction. Can be displayed with arrow symbols to show flow direction. There is one point at the upstream end for each stream network feature

Data and Resources

Dataset Extent

Latitude: 48.0° to 60.0°
Longitude: -139.5° to -113.5°

Additional Information

Purpose

This feature layer is used for display purposes to show stream flow direction.

Lineage Statement

The upstream end points of each stream network feature were extracted and a downstream direction to the next vertex was calculated. This value is stored as an attribute in the feature attribute table.

Object Description

Object Name: WHSE_BASEMAPPING.FWA_STREAM_DIRECTIONS_SP

Short Name: FWSTRMDRCT
Comments: Directional arrowheads for use with web mapping applications only. Arrowheads are in various sizes for scale dependant display. Arrowhead orientation is based on the vertex order of the referenced linear element.

Column Name Short Name Data Type Data Precision Comments
STREAM_DIRECTION_ID STRMDRCTND NUMBER 18 STREAM DIRECTION ID is a surrogate key for the STREAM DIRECTION SP record. i.e. 1
LINEAR_FEATURE_ID LNRFTRD NUMBER 18 The LINEAR FEATURE ID is a unique numeric identifier used to identify the STREAM NETWORKS SP spatial line that this STREAM DIRECTION provides direction for. i.e 7209923
DOWNSTREAM_DIRECTION DWNSTRMDRC NUMBER 38 DOWNSTREAM DIRECTION is the direction in decimal degrees, counterclockwise from east, where east is 0, north is 90, west is 180, and south is 270, e.g., 179.227053, which indicates almost due west.
FEATURE_CODE FTRCD VARCHAR2 10 FEATURE CODE contains a value based on the Canadian Council of Surveys and Mapping's (CCSM) system for classification of geographic features.
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.
