Dominion Land Survey (DLS) and Public Land Survey System (PLSS)
Differences between Dominion Land Survey (DLS) and Public Land Survey System (PLSS).
The DLS is based on the American PLSS with some distinctive differences. Two main differences between PLSS and the DLS are:
The Public Land Survey System[PLSS] used in USA system starts numbering the townships with 1 at the east as the Canadian but the 1 is at the top right-hand corner. The DLS starts the 1 at the south-east corner, starting at the border.
The PLSS did not include road allowances. DLS includes road allowances which add to the grid which gives problems to accuracy.
