Object Description

Object Name: WHSE_TERRESTRIAL_ECOLOGY.ERC_ECODIVISIONS_SP

Short Name: ERC_ECODIV
Comments: ECODIVISIONS SP represent areas of broad climatic and physiographic uniformity. There are seven ecodivsions occurring within British Columbia. Ecodomains and ecodivsions place British Columbia in a global context. Ecodivsions are used in national state of the environment reporting. This is a mutipart feature class.

Column Name Short Name Data Type Data Precision Comments
ECODIVISION_CODE CDVSNCD VARCHAR2 3 ECODIVISION CODE is a three letter Ecodivision primary unique code. (e.g. HCH, SAH)
FEATURE_CODE FTRCD VARCHAR2 10 FEATURE CODE is a standard alphanumeric code to identify the type of feature represented by the spatial data. A feature code is most importantly a means of linking a feature to its name and definition. For example, the code GB15300120 on a digital geographic feature links it to the name "Lake - Dry" with the definition "A lake bed from which all water has drained or evaporated." The feature code does NOT mark when it was digitized, what dataset it belongs to, how accurate it is, what it should look like when plotted, or who is responsible for updating it. It only says what it represents in the real world. It also doesn't even matter how the lake is represented. If it is a very small lake, it may be stored as a point feature. If it is large enough to have a shape at the scale of data capture, it may be stored as an outline, or a closed polygon. The same feature code still links it to the same definition.
ECODIVISION_NAME CDVSNNM VARCHAR2 50 ECODIVISION NAME is the ecodivision full name. (e.g. "COOL HYPERMARITIME AND HIGHLANDS","SEMI-ARID STEPPE HIGHLANDS").
PARENT_ECODOMAIN_CODE PRNTCDMNCD VARCHAR2 3 PARENT ECODOMAIN CODE is the code for the Ecodomain that completely contains this Ecodivision. Foreign key to ECODOMAINS SP.
EFFECTIVE_DATE FFCTVDT DATE 7 EFFECTIVE DATE is the date the feature was first included in the dataset.
EXPIRY_DATE XPRDT DATE 7 EXPIRY DATE is the date the feature was removed from the dataset, or replaced with a new feature.
GEOMETRY GEOMETRY SDO_GEOMETRY 1
OBJECTID OBJECTID NUMBER 38
SE_ANNO_CAD_DATA BLOB 4000
FEATURE_AREA_SQM FEAT_AREA NUMBER 19 FEATURE_AREA_SQM is the system calculated area of a two-dimensional polygon in square meters
FEATURE_LENGTH_M FEAT_LEN NUMBER 19 FEATURE_LENGTH_M is the system calculated length or perimeter of a geometry in meters
