# 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.

## Group¶

This operation belongs to the group of Area operators

Area operations

## Examples¶

1. • pcrcalc
