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