Detailed Soil Surveys

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.

  • Version 1 was the electronic data structure (SMUF/SNF/SLF) used in the original CanSIS system dating from the early 1970's.
  • Version 2 introduced a new data structure based on components. This version was created in the 1990's by converting version 1 data.
  • Version 3 was created in the 2010's by amalgamating version 2 data. It introduced some minor refinements to the version 2 data structure to provide closer alignment with the SLC data structure.
