Ecosections are areas with minor physiographic and macroclimatic or oceanographic variations. There are 114 ecosections in British Columbia varying from pure marine units to pure terrestrial units. Ecosections are meant to be mapped at small scales (1:250,000) for resource emphasis and area planning

Object Description

Object Name: WHSE_TERRESTRIAL_ECOLOGY.ERC_ECOSECTIONS_SP

Short Name: ERC_ECOSEC
Comments: ECOSECTIONS SP represent areas with minor physiographic and macroclimatic or oceanographic variations. Ecosections are used for resource emphasis and area planning. This is a multipart feature class.

Column Name Short Name Data Type Data Precision Comments
ECOSECTION_CODE ECOSEC_CD VARCHAR2 3 ECOSECTION CODE is three letter Ecosection primary unique code (e.g. TEB, PEP) .
FEATURE_CODE F_CODE 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.
ECOSECTION_NAME ECOSEC_NM VARCHAR2 50 ECOSECTION NAME is theEcosection full name (e.g. "Whitehorse Upland", "Tatshenshini Basin").
PARENT_ECOREGION_CODE PRNT_ECO_C VARCHAR2 3 PARENT ECOREGION CODE is the code for the Ecoregion that completely contains this Ecosection. Foreign key to ERC_ECOREGIONS_SP.
EFFECTIVE_DATE EFFEC_DAT DATE 7 EFFECTIVE DATE is the date the feature was first included in the dataset.
EXPIRY_DATE EXPIRY_DAT 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 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
