Map Unit Table (MAPUNIT)
This table contains non-standard attributes which apply to the entire Soil Map Unit (i.e. polygon(s)), and thus could not be placed in the Component Table.
|1||MAPUNIT||string||68||Map Unit Identifier|
The proportion of the polygon occupied by each separate component of a map unit is identified. However, their location within any polygon is not defined. The data model limits the number of components to a maximum of three, even though more may have been recognized in the field.
Note that the dominant component for some map units will be a non-soil (i.e. water, rock, or ice). Analyses involving dominant soil components should take this fact into account.
