Object Description

Object Name: WHSE_FOREST_VEGETATION.RANGE_NATURAL_BARRIER_LINE_SVW

Short Name: NAT_BAR_LN
Comments: Holds information to identify major classes of range improvements. Each class contains a barrier attributes, the geometry and identification fo the specific type of the range barrier feature.

Column Name Short Name Data Type Data Precision Comments
FEATURE_CODE F_CODE VARCHAR2 10 An alphanumeric code used to identify a geographic feature.
BARRIER_FEATURE_GROUP_CODE BAR_FGR_C VARCHAR2 20 A code to identify the groupings for barrier featue . For example if the barrier features may be water features or vegetation features so water or vegetation would be feature groups.
BARRIER_FEATURE_CODE BAR_FC VARCHAR2 20 A code to identify the type of barrier feature. For example if the barrier feature group type is water features the barrier feature type might be lake, river, ect.
DISTRICT_RESPONSIBLE_CODE DIST_REP_C VARCHAR2 3 The org unit code within the Ministry of Forests and Range which identifies the district responsible for the natural barrier feature.
BARRIER_DEPTH BAR_DEPTH NUMBER 5 The linear depth/height/width that constitutes the barrier of a tree-line natural range barrier measured in meters.
FIELD_CONDITION_CODE FLD_CND_C VARCHAR2 20 A code to identify the condition of a feature as observed in the field. (E.g. good, fair, poor)
FIELD_OBSERVATION_DATE FLD_OBS_D DATE 7 Specifies the date that the field condition was observed.
DATA_SOURCE_CODE DATA_SRC_C VARCHAR2 20 A code to identify the data source origin of a feature. (E.g. Air Photo, Forest Cover Maps, Satellite)
CAPTURE_METHOD_CODE CAP_METH_C VARCHAR2 20 A code to identify the method of data capture for the given feature. (E.g. Photogrammetric,Ortho-Photography, Sketch Map)
CAPTURE_DATE CAP_D DATE 7 Specifies the date that the feature was captured electronically from the specified Data Source using the specified Capture Method.
LOAD_SOURCE LOAD_SRCE VARCHAR2 30 Specifies the date that the feature was captured electronically from the specified Data Source using the specified Capture Method.
LOAD_DATE LOAD_DATE DATE 7
FEATURE_LENGTH_M NUMBER 19
GEOMETRY GEOMETRY SDO_GEOMETRY 64 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.
