Detailed Soil Surveys (version 2)

Soil surveys have been published for most of the agricultural areas, and many surrounding areas, across Canada. Data from these surveys comprise the most detailed soil inventory information in the NSDB. These products are available in two forms: the individual datasets described on this page, and the soil survey compilations for each province.

The significant characteristics of the legacy soil surveys are as follows.

The relationships of the various files may be understood by examining the data model.

Dataset Descriptions

  1. Data model
  2. SOIL coverage
  3. Detailed soil survey databases
    1. Polygon Attribute Table (PAT)
    2. Land Area Table (LAT)
    3. Map Unit Table (MAPUNIT)
    4. Component Table (CMP)
    5. Soil Name Table (SNT)
    6. Soil Layer Table (SLT)
  4. Spatial reference layers
    1. CIVIL coverage
    2. HYDRO coverage
  5. Documentation
    1. DOC file
    2. readme.txt


The Component Table and the other attribute tables that describe the SOIL coverage are in INFO format.  These tables will be found in the INFO directory where the coverage was imported.

In order to display the soil information found in the SOIL coverage, it should be mapped in conjuction with the HYDRO coverage.  The detailed soil surveys use the same Component Table concept as the Soil Landscapes of Canada, and the attributes in this file are mapped in a similar fashion.
