Precision for derived coverages


Determines the coordinate precision for derived coverages. Also known as the processing rule.

Derived coverage are those derived from tools that accept input data to derive the output coverage, for example, coverages created by running the Buffer coverage tool.

Derived_Precision <HIGHEST | LOWEST | SINGLE | DOUBLE>


Parameters Explanation Datatype
<HIGHEST | LOWEST | SINGLE | DOUBLE> The precision for derived coverages.

  • HIGHEST—The coordinate precision of the output coverage will be the same precision as the input coverage that has the highest precision. This is the default.
  • LOWEST—The coordinate precision of the output coverage will be the same precision as the input coverage that has the lowest precision.
  • SINGLE—The coordinate precision of the output coverage will always be single precision, regardless of the precision of the input coverage.
  • DOUBLE—The coordinate precision of the output coverage will always be double precision, regardless of the precision of the input coverage.
