Convert Legal Subdivision (LSD) codes to GPS coordinates
GRID turns Western Canada Dominion Land Survey (DLS) identifiers into precise latitude/longitude coordinates, section polygons, and maps. Enter a Legal Subdivision code such as 08-15-052-04W5 and get its exact location — or click anywhere on the map to reverse geocode a point back to its LSD. Alberta lookups use official ATS v4.1 survey data (±3 m); Saskatchewan, Manitoba, and BC's Peace River Block use mathematical DLS grid calculations.
Survey-accurate
Alberta results come from the official Alberta Township System (ATS v4.1) survey fabric — accurate to about ±3 metres.
Western Canada coverage
Alberta, Saskatchewan, Manitoba, and the DLS-coded Peace River Block of British Columbia are all supported.

Frequently asked questions
What is a Legal Subdivision (LSD)?
A Legal Subdivision is the smallest unit of the Dominion Land Survey (DLS) system used across Western Canada. Each 1-mile-square section is divided into a 4×4 grid of 16 Legal Subdivisions, numbered 1–16. An LSD is roughly a quarter-mile square (about 16 hectares) and is written as LSD-Section-Township-Range-Meridian, for example 08-15-052-04W5.
How do I convert an LSD to latitude and longitude?
Enter the Legal Subdivision code in the lookup box above and GRID returns its centre-point latitude/longitude plus the full section polygon. You can copy the coordinates, view them on the map, or export them. There is no account required to start.
What is the Dominion Land Survey (DLS) system?
The Dominion Land Survey is the grid used to divide land in the Prairie provinces into townships, ranges, sections, and legal subdivisions, measured west from a series of meridians and north from the 49th parallel. It is the basis for legal land descriptions and well locations in Alberta, Saskatchewan, and Manitoba.
What is the difference between LSD and NTS?
LSD (the Dominion Land Survey grid) is used for land in the Prairie provinces, while NTS (the National Topographic System) is a map-sheet grid used for well locations in most of British Columbia. GRID converts DLS/LSD codes; NTS-coded BC wells are not yet supported.
How accurate are the coordinates?
Alberta results use the official ATS v4.1 survey data and are accurate to roughly ±3 metres. Saskatchewan, Manitoba, and BC Peace River results are computed from DLS grid geometry and are approximate. Coordinates are for general reference, not for legal or survey purposes.
