Determines the location of Coal Tenures within the Province of British Columbia. It is established under the authority of the Petroleum and Natural Gas Grid Regulation. It is defined by a set of UTM coordinates which approximate NAD 27 latitude and longitude positions. Units are the finest level of the Coal Grid. They are defined by UTM coordinates for their corners and the mid points of the four sides. A unit is the base building block for creating the Coal Grid. In a block there are 100 units, 10 rows by 10 columns, and numbered consecutively, starting in the southeast corner. The units are numbered 1 to 10, 11 - 20 etc. always reading from right to left. E.G. 082E05D007

Additional Information

Purpose

The Coal Grid is used to show the spatial representation or extent of Coal Tenures within the Province of British Columbia. Units are the finest level of the Coal Grid. They are defined by UTM coordinates for their corners and the mid points of the four sides. A unit is the base building block for creating the Coal Grid. In a block there are 100 units, 10 rows by 10 columns, and numbered consecutively, starting in the southeast corner. The units are numbered 1 to 10, 11 - 20 etc. always reading from right to left.

Object Description

Object Name: WHSE_MINERAL_TENURE.MTA_COAL_GRID_UNIT_SP

Short Name: MTA_CL_GRD
Comments: Units are the finest level of the coal grid. They are defined by UTM coordinates for their corners and the mid points of the four sides. a unit is the base building block for creating the coal grid. There are 100 units is a block, 10 rows by 10 columns, and numbered consecutively, starting in the southease corner. The units are number 1 to 10, 11 - 20 etc. always reading from right to left.

Column Name Short Name Data Type Data Precision Comments
GRID_ID GRID_ID VARCHAR2 11 GRID ID is the unique identifier for the polygon and is a combination of the mapsheet id, the group id, the block id, and the unit id. This is a user maintained primary key. e.g., 082E03K053
MAP_SHEET_ID MAPSHEET VARCHAR2 4 MAP_SHEET_ID is similar to the naming of the 1:250,000 NTS maps sheets. e.g., 082E
GROUP_ID GROUP_ID VARCHAR2 2 GROUP_ID is the last 2 character of the 1:50,000 NTS map sheet which it approximates. e.g., 03 for NTS sheet 082E03
BLOCK_ID BLOCK_ID VARCHAR2 1 BLOCK_ID is the one character name of the block and must be in the range of A to L
UNIT_ID UNIT_ID VARCHAR2 3 UNIT ID is the three character name of the unit and must be in the range of 1 to 100
UTM_ZONE UTM_ZONE VARCHAR2 2 UTM ZONE is a segment of the Earth's surface 6 degrees of longitude in width. The zones are numbered eastward starting at the meridian 180 degrees from the prime meridian at Greenwich. There are five zones numbered 7 through 11 that cover British Columbia, e.g., Zone 10 with a central meridian at -123 degrees.
LABEL LABEL VARCHAR2 15 LABEL is the recommended label for mapping and presentation. e.g., 082E
