The National Soil DataBase (NSDB)

The NSDB is the set of computer readable files which contain soil, landscape, and climatic data for all of Canada. It serves as the national archive for land resources information that was collected by federal and provincial field surveys, or created by land data analysis projects.

The NSDB includes GIS coverages at a variety of scales, and the characteristics of each named soil series. The principal types of NSDB data holdings (ordered by scale) are as follows.

National Ecological Framework (EcoZones, EcoRegions, and EcoDistricts)

intended for use at scales of 1:30 million to 1:1 million
coverage includes the entire land mass of Canada
polygons are nested groupings of Soil Landscapes of Canada polygons
data is available from other federal and provincial agencies

Soil Map of Canada / Land Potential DataBase (LPDB)

scale of 1:5 million
coverage includes the entire land mass of Canada
originally produced in the early 1980s; much of this information is outdated and better data is available (National Ecological Framework, Soil Landscapes of Canada)

Agroecological Resource Areas (ARAs)

scale of 1:2 million
coverage includes the three prairie provinces
data includes climatic, economic, crop, soil, and landscape attributes
polygons are similar to EcoDistricts (but not identical)
better soils and climate data is available (Soil Landscapes of Canada, National Ecological Framework)

Soil Landscapes of Canada (SLC)

scale of 1:1 million
coverage includes the entire land mass of Canada
data includes major soil and landscape attributes

Canada Land Inventory (CLI)

scale of 1:250,000
coverage includes most agricultural lands in Canada
data includes capability for Agriculture, Forestry, Wildlife, Recreation, Ungulates
produced in the 1960's, 1970's and early 1980s
better soils data and CLI ratings at larger scales are available (Detailed Soil Surveys)

Detailed Soil Surveys

scale varies (1:20,000 to 1:250,000)
coverage includes much of the significant agricultural areas of Canada
data content varies, availability of digital data varies
printed provincial indexes are available; query the NSDB data holdings

Data obtained from other agencies

These datasets are not normally available for distribution.
Data digitized by CanSIS are not subject to the data release policies of the agency of origin, and these datasets are available for distribution. These datasets include base maps, cultural, and hydrological information.
