Map Unit Table

Filename

  • {covername}_MU.DBF (source file)
  • {covername}.MAPUNIT (in arc/info workspace)

Description

This table contains attributes which apply to the entire Soil Map Unit (i.e. polygon(s)), and thus could not be placed in the Component Table.

Contents

Field Field Name Type Width Decimal 
Places
Description 
1 MAPUNIT CHAR 68   Linkage Key 
2 INTERP  CHAR 1   Interpretation (optional) 
3 SLC-V2.2 INTEGER 6   SLC v2.2 polygon number  (optional)

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.
