Topographic mapping in Canada was originally undertaken by many different agencies, with the Canadian Army’s Intelligence Branch forming a survey division to create a more standardized mapping system in 1904. The indexing system used today was established in 1923, and the map catalogue officially became the National Topographic System in 1926 ...

These maps employ the 1927 North American Datum (NAD27); conversion or a change in settings is necessary when using a GPS which by default employ the WGS84 geodetic datum. Beginning in 2009, the USGS made available digital versions of 7.5 minute quadrangle maps based on GIS data that use the NAD83 datum, which is typically within one meter of ...

The surveying of western Canada was divided into five basic surveys. Each survey's layout was slightly different from the others. The first survey began in 1871 and ended in 1879 and covers some of southern Manitoba and a little of Saskatchewan. The second and smallest survey, in 1880, was used in only small areas of Saskatchewan.
Canada covers 9,984,670 km 2 (3,855,100 sq mi) and a panoply of various geoclimatic regions, of which there are seven main regions. [9] Canada also encompasses vast maritime terrain, with the world's longest coastline of 243,042 kilometres (151,019 mi). [20] The physical geography of Canada is widely varied.

Geologic units and processes are investigated on a large scale to reach a synthesized picture of the geological development of the country. Geologically, Canada is one of the oldest regions in the world, with more than half of the region consisting of precambrian rocks that have been above sea level since the beginning of the Palaeozoic era.
