Object Description


Short Name: ERC_ECODOM
Comments: ECODOMAINS SP represent areas of broad climatic uniformity. There are three terrestrial and one oceanic ecodomain occurring in British Columbia. Ecodomains are used in global environmental strategies. This is a multipart feature class.

Column Name Short Name Data Type Data Precision Comments
ECODOMAIN_CODE CDMNCD VARCHAR2 3 ECODOMAIN CODE is a three letter Ecodomain primary unique code. (e.g. POL, HUT, DRY, COO) .
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.
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 featur
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.
FEATURE_AREA_SQM AREA_SQM 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
