DLS Grid
The grid covers most of Western Canada's sedimentary basin. It divides
land into regular boxes called townships, which are 6 miles on each side.
Three coordinates (Township,
Range, and Meridian),
identify each township. GeoVista uses a township and range coordinate pair, in conjunction with a meridian
number, to identify a specific township in the .
- Township
Numbering - Townships are numbered from 1 to 126, south-to-north.
- Range
Numbering - Ranges are numbered from 1 to 30, east-to-west, at
township 1, and from 1 to 23, east-to-west, at township 126.
- Due to the curvature of the earth, there are fewer ranges between meridians
at the northern extreme of the DLS area than at the southern extreme.
- Size
of a Township - Each DLS township is divided into 36 sections,
which are one mile on a side and numbered in a left-to-right/right-to-left
pattern.
- Size
of a Section - Each DLS section is divided into 16 Local Subdivisions
(), which are 1320 feet on a side and numbered in the same way as the
sections.
