and, &, pcrand

and

Boolean-and operation

Result = expression1 and expression2 # pcrcalc
Result = expression1 & expression2 # python
Result = pcrand(expression1,expression2) # python
expression1
spatial, non spatial boolean
expression2
spatial, non spatial boolean
Result
spatial; non spatial if expression1 and expression2 are non spatial boolean

Operation

The cell values on expression1 and expression2 are interpreted as Boolean values; where 1 is TRUE and 0 is FALSE. For each cell the Boolean and evaluation is performed: if both expression1 and expression2 have a cell value 1 (TRUE) Result has a cell value 1 (TRUE) on the corresponding cell; if expression1 or expression2 or both have a cell value 0 (FALSE) Result has cell value 0 (FALSE).

and expression1 Result
expression2 True True True
expression2 True False False
expression2 False True False
expression2 False False False

Notes

A cell with missing value on expression1 or expression2 or on both expressions results in a missing value on Result at the corresponding cell.

Group

This operation belongs to the group of Boolean operators

Examples

  1. • pcrcalc
    binding
    Result = Result.map;
    Expr1 = Expr1.map;
    Expr2 = Expr2.map;
    initial
    report Result = Expr1 and Expr2;

    • python
    Expr1 = readmap(“Expr1.map”)
    Expr2 = readmap(“Expr2.map”)
    Result = Expr1 & Expr2
    Result.map Expr1.map Expr2.map
