MAPUNIT 
Polygon Identifier

Description

Polygon identifier used to relate between the PAT and the CMP tables.

The MAPUNIT field was generated for each polygon by appending the PROVINCE and NSDB-ID codes with the map unit symbol that identifed that polygon on the original printed soil map.  The MAPUNIT usually encodes meaningful information about the soil type and topography; the same information which is found in the CMP table.  Within any one survey, a group of polygons with similar properties may be coded with the same MAPUNIT.
