Data and Resources

Dataset Extent

Latitude: 48.0° to 60.0°
Longitude: -139.5° to -113.5°

Additional Information

Purpose

Used to derive two spatial views; 1) Endangered Species and Ecosystems - Non Sensitive Occurrences 2) Endangered Species and Ecosystems - Sensitive Occurrences.

Data Quality
Lineage Statement

The Conservation Data Centre follows Natureserve Element Occurrence Data Standards (2003). Records mapped prior to 2003 were mapped to an older standard.

Object Description

Object Name: WHSE_TERRESTRIAL_ECOLOGY.BIOT_OCCR_AREA_SP

Short Name: BTCCRRSP
Comments: Occurrence area is a specific geographic location that represents a habitat capable of sustaining or contributing to the survival of specified species. This layer includes Endangered Species and other species habitats.

Column Name Short Name Data Type Data Precision Comments
OCCR_AREA_SP_ID CCRRSPD NUMBER 10 Primary unique numeric identifier for a Polygon.
FEATURE_CODE FTRCD VARCHAR2 10 A standard numeric 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.
FEATURE_ID FEATURE_ID NUMBER 10 Unique occurence area identifier used to associated attribute data.
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 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
