BCGS 1:2,500 scale grid, North Amercian Datum 1983. The British Columbia Geographic System is a geographic system in which the coverage in minutes and seconds of longitude is double the coverage in minutes and seconds of latitude for sheets at all scales

Data and Resources

Dataset Extent

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

Additional Information

Purpose

To provide an index grid for BCGS 1:2,500 scale maps.

Lineage Statement

This 1:2,500 grid was derived from the 1:5,000 grid (which was derived from the 1:10,000 grid) by generating an offset 1:5,000 grid and then overlaying that with the original 1:5,000 grid. The mapsheet numbers were joined from a point coverage that was generated using a process that determined the mapsheet numbers and positions from lat/long coordinates.

Object Description

Object Name: WHSE_BASEMAPPING.BCGS_2500_GRID

Short Name: BCGS2500GR
Comments: British Columbia Geographic Series 1:2 500 Mapsheet Grids. Each mapsheet is a fourth of a 1:5,000 mapsheet numbered 1 through 4. The neatlines were defined and created in geographics, and reprojected to BC Albers. Each of the mapsheets is .75 minutes (45 seconds) latitude by 1.5 minutes (90 seconds) longitude.

Column Name Short Name Data Type Data Precision Comments
MAP_TILE MAP_TILE VARCHAR2 32 BCGS 1:2 500 Map number, e.g., 092A001111, 114B100444. The map tiles are numbered: 1, 2, 3, 4
MAP_TILE_DISPLAY_NAME MPTLDSPLNM VARCHAR2 32 BCGS 1:2 500 Map number - conforms to BCGS Specifications Document - suitable for representational display, e.g., 92A.001.1.1.1, 114B.100.4.4.4
FCODE FCODE VARCHAR2 10 FCODE has now been renamed to FEATURE CODE in future models. 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.
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
