Object Description

Object Name: WHSE_BASEMAPPING.FWA_WETLANDS_POLY

Short Name: FWWTLNDSPL
Comments: Contains all wetland polygons for the province. Does not contain multipart geometries. Spatial type: simple polygon

Column Name Short Name Data Type Data Precision Comments
WATERBODY_POLY_ID WTRBDPLD NUMBER 18 The WATERBODY POLY ID is the unique key for the waterbody polygon spatial layer. It is not applied to the warehouse model only, i.e., it originates with the source FWA system.
WATERSHED_GROUP_ID WTRSHDGRPD NUMBER 18 An automatically generate id that uniquely identifies the watershed group feature.
WATERBODY_TYPE WTRBDTP VARCHAR2 1 The type of waterbody. Possible values include: 'L' (lake), 'R' (double lined river), 'W' (wetland), 'X' (manmade river or lake), or 'G' (glacier or icefield).
WATERBODY_KEY WTRBDK NUMBER 10 A unique identifier associated with waterbodies in order to group polygons that make up a single waterbody.
AREA_HA AREA_HA NUMBER 38 Area of polygon (hectares).
GNIS_ID_1 GNIS_ID_1 NUMBER 10 A BCGNIS (BC Geographical Names Information System) feature id attached to a waterbody or island, if applicable. In a grouped system the feature id of the BCGNIS group is provided here and any subsequent names provided in gnis_id2 and gnis_id3. Note: For Vancouver Island, Graham Island, and Moresby Island the names are not attached to the label points.
GNIS_NAME_1 GNSNM1 VARCHAR2 80 The name of the first BCGNIS (BC Geographical Names Information System) feature id (an English name was used where available, otherwise another language was selected).
GNIS_ID_2 GNIS_ID_2 NUMBER 10 A second BCGNIS (BC Geographical Names Information System) feature id attached to a waterbody or island, if applicable.
GNIS_NAME_2 GNSNM2 VARCHAR2 80 The name of the second BCGNIS (BC Geographical Names Information System) feature id (an English name was used where available, otherwise another language was selected).
GNIS_ID_3 GNIS_ID_3 NUMBER 10 A third BCGNIS (BC Geographical Names Information System) feature id attached to a waterbody or island, if applicable.
GNIS_NAME_3 GNSNM3 VARCHAR2 80 The name of the third BCGNIS (BC Geographical Names Information System) feature id (an English name was used where available, otherwise another language was selected).
BLUE_LINE_KEY BLLNK NUMBER 10 The blue line key of the controlling route through the waterbody.
WATERSHED_KEY WTRSHDK NUMBER 10 The watershed key of the controlling rout through the waterbody.
FWA_WATERSHED_CODE FWWTRSHDCD VARCHAR2 143 The watershed code of the controlling route through the waterbody.
LOCAL_WATERSHED_CODE LCLWTRSHDC VARCHAR2 143 The local watershed code associated with the waterbody.
WATERSHED_GROUP_CODE WTRSHDGRPC VARCHAR2 4 The watershed group codeof the watershed the feature is contained within.
LEFT_RIGHT_TRIBUTARY LFTRGHTTRB VARCHAR2 7 A value attributed via the watershed code to all waterbodies indicating on what side of the watershed they drain into.
WATERBODY_KEY_50K WTRBDK50K NUMBER 10 The 'best' matched waterbody from the 1:50K Watershed Atlas. In cases where there are multiple matches to features in the 1:50K watershed atlas the match with the greatest overlapping area was used.
WATERSHED_GROUP_CODE_50K WTRSHDGRP1 VARCHAR2 4 The group code from the 1:50K Watershed Atlas associated with the waterbody key 50k.
WATERBODY_KEY_GROUP_CODE_50K WTRBDKGRPC VARCHAR2 55 The waterbody key 50K with the group code 50K concatenated.
WATERSHED_CODE_50K WTRSHDCD50 VARCHAR2 45 The 1:50K Watershed Atlas watershed code associated with the waterbody key 50K.
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
OBJECTID OBJECTID NUMBER 38
SE_ANNO_CAD_DATA BLOB 4000
FEATURE_AREA_SQM NUMBER 19 FEATURE_AREA_SQM is the system calculated area of a two-dimensional polygon in square meters
FEATURE_LENGTH_M NUMBER 19 FEATURE_LENGTH_M is the system calculated length or perimeter of a geometry in meters
