These guidelines summarize the land description system for parcels north of latitude 60° N. For more detailed information see Section 4 of the Canada Oil and Gas Land Regulations. [Geographic coordinates are referenced to North American Datum 1927 (NAD27).]
Land areas are divided into grids, grids into sections, and sections into units.
Grids are bounded to the east and west by successive meridians of longitude:
To the north and south, the boundaries of grids are defined by straight lines joining the points of intersection of their east and west boundaries with successive parallels of latitude spaced every 10'(e.g., 60° 00' N and 60° 10' N). Every grid area is referred to by the latitude and longitude co-ordinates of its northeast corner (e.g., 60° 10' N, 122° 00'W).
The number of sections into which a grid is divided depends on the latitude where the grid is located.
A section is bounded to the east and west by meridians:
To the north and south, the boundaries of sections are defined by straight lines drawn parallel to the north and south boundaries of the grid and spaced at intervals of 1/10 of the distance between these boundaries.
Thus, grids have 100, 80 or 60 sections (10x10, 8x10, or 6x10) depending on their location.
The sections are numbered and each is referred to by its number (see the example in Figure 1).
Every section is divided into 16 equal units, each of which is identified by a letter (see Figure 2).
