areamaximum

areamaximum

Maximum cell value within an area

Result = areamaximum(expression, areaclass)

expression

spatial ordinal, scalar

areaclass

spatial boolean, nominal, ordinal

Result

spatial type of expression

Operation

areaclass Identifies the class to which a cell belongs: cells with corresponding values on areaclass are member of a separate class. For each separate class the maximum expression value of the cells belonging to that class is determined. This value is assigned to all cells belonging to that class. This is done for all classes and saved as Result.

Notes

A cell with a missing value areaclass is assigned a missing value on Result at the corresponding cell.
