Convert Coordinates to LSD — Find the LSD from GPS Coordinates
Enter latitude and longitude coordinates and find which LSD (Legal Subdivision) they fall in. Reverse geocode GPS to LSD for Alberta, Saskatchewan, and Manitoba.
Convert Coordinates to LSD
You have a GPS pin — a latitude and longitude from a field device, a map click, or a regulatory document — and you need the specific LSD that contains it. Not just the section or township: the LSD number, which identifies the exact 40-acre parcel.
That's what this guide covers. Township Canada takes your coordinates and returns the full legal land description down to the LSD level, with the parcel highlighted on the DLS survey grid so you can confirm it visually before copying the result.
Why LSD Specifically?
The Dominion Land Survey system divides land into a hierarchy: Townships → Sections → LSDs. A section is one square mile (640 acres). Each section contains 16 LSDs, each covering roughly 40 acres.
For many documents — well licenses, surface lease agreements, AER regulatory filings — the LSD is the required level of precision. A quarter section (NE, NW, SE, SW) covers 160 acres; that's four LSDs. If a well site sits in the SW quarter of a section, it could be LSD 1, 2, 3, or 4. The regulator needs to know which one. GPS coordinates tell you exactly where the well is. The LSD number is what goes on the paper.
This page focuses on that specific conversion: coordinates in, LSD out. For a broader overview of converting GPS to any legal land description format, see the GPS to legal land description guide.
How LSDs Are Numbered Within a Section
LSDs are numbered 1 through 16 within each section, following a serpentine (boustrophedon) pattern starting from the southeast corner:
- Bottom row (south): 1 (SE corner), 2, 3, 4 (SW corner) — east to west
- Second row: 5 (SW side), 6, 7, 8 (SE side) — west to east
- Third row: 9 (SE side), 10, 11, 12 (SW side) — east to west
- Top row (north): 13 (SW side), 14, 15, 16 (NW corner) — west to east
So LSD 1 is always in the southeast corner of a section, and LSD 16 is in the northwest corner. A GPS coordinate near the center-south of a section will typically fall in LSD 5 or 6. Knowing this pattern helps you sanity-check a result in the field.
Step-by-Step: Find the LSD from Coordinates
Step 1: Open Township Canada
Go to Township Canada and look for the coordinate search option. The tool accepts decimal degree format (e.g., 52.45, -113.53) directly in the search bar.
Step 2: Paste Your Coordinates
Enter your latitude and longitude. Latitude first, then longitude. For Alberta locations, longitude will be a negative number (west of the prime meridian). Common formats accepted:
52.45, -113.53(decimal degrees, comma-separated)52.4500° N, 113.5300° W
Township Canada identifies which LSD the coordinate falls within and returns the full legal land description.
Step 3: Read the LSD Result
The result shows the complete legal land description at every level. For the example coordinates above, you'd see something like:
14-08-042-26W4
Reading left to right: LSD 14, Section 8, Township 42, Range 26, West of the 4th Meridian. That places this parcel near Ponoka in central Alberta — an area with active oil and gas development and mixed farmland.
The LSD (14) is the key number for your well license or surface lease document. It tells the reader this is the northwest corner of Section 8, not the southeast or any of the 15 other 40-acre parcels in that same section.
Step 4: Confirm on the Grid
Township Canada displays the section grid with your LSD highlighted. Before you copy the result, take five seconds to confirm the highlighted parcel is where you expect it to be relative to nearby roads, water bodies, or other landmarks. A transposed digit in the coordinates can shift you to a completely different parcel; the visual check catches that immediately.
Step 5: Copy the LSD Format
Use the copy button to grab the LSD in the standard format: 14-08-042-26W4. This is the format accepted by most Alberta regulatory forms, land title documents, and GIS import tools. The LSD converter page has more detail on format variations if your document expects a different notation.
A Worked Example
A field technician drops a GPS pin at a well site in central Alberta. The device records:
Latitude: 52.45, Longitude: -113.53
Entering these coordinates into Township Canada returns:
- LSD: 14
- Section: 08
- Township: 042
- Range: 26
- Meridian: W4
Full description: 14-08-042-26W4
On the DLS grid, LSD 14 sits in the northwest area of Section 8 — consistent with the field crew's notes that the well pad is north of the central access road through that section. The technician copies the LSD and enters it directly into the AER well license form.
Coordinate Precision Matters
An LSD is roughly 800 metres by 800 metres at Alberta latitudes. A GPS coordinate accurate to two decimal places (e.g., 52.45) has about 1 km of uncertainty — which is enough to land you in the wrong LSD. For regulatory documents, use coordinates with at least four decimal places (e.g., 52.4512, -113.5348). Most field GPS devices and smartphone apps record this level of precision by default.
If your coordinates only have two decimal places, treat the LSD result as an approximation and verify against a known landmark or bearing from a surveyed location.
