Quaternary Alluvium and Cover is a data set that is represented as a cover layer on the maps of MapPlace. It is part of the British Columbia Digital Geology, which is the data source used for the seamless province-wide, up-to-date, and detailed bedrock geology. The bedrock geology integrates all details of compilations from 1:50,000 to 1:250,000. The data is maintained by a geospatial frame data model with techniques used to simplify the integration process and shorten the time frame from field mapping, compilation, integration, to data delivery. Quaternary Alluvium and Cover with the related data sets, Bedrock Geology and Quaternary Alluvium and Cover, are displayed on MapPlace and MapPlace 2 and is available for download in shapefile and GeoPackage formats.

Object Description

Object Name: WHSE_MINERAL_TENURE.GEOL_QUATERNARY_POLY

Short Name: QTRNRY_PLY

Column Name Short Name Data Type Data Precision Comments
QUATERNARY_ID QTRNRD VARCHAR2 240 Surrogate primary key
FEATURE_CODE FTRCD VARCHAR2 10 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."
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
