Relationships
- A record in this file is unique with respect to MAPUNIT.
- MAPUNIT is
required to relate (1:N) to the PAT.
Limitations
The proportion of the polygon occupied by each separate component
is identified. However, their location within the polygon is not
defined. While the data model does not restrict the number of
components or the proportion of the polygon that they occupy,
restrictions have been recommended from a subject
matter/organization standpoint.
Note that the dominant component for some polygons will be
a non-soil (i.e. water, rock, or ice). Analyses involving dominant
soil components should take this fact into account.
