Mapunit - Soilunit discussion
Soil map units are identified by unique symbols on the Soils of Canada map. The initial letter of the symbol indicates the soil Order of the dominant soil in the map unit. The number following the letter indicates the Great Group.
The number under the taxonomic map symbol is a unique numerical identifier. For example, Al/1 signifies a unit of Brown Chernozemic soil, area number l. In the MAPUNIT field of the data base, the area identifier is converted to a three digit number (in this case 001) following the soil Great Group, in which case the designations for this soil map unit would be:
MAPUNIT A1001 SOILUNIT A1/1
