[Qgis-user] Raster calculator

[Alexandre Neto]

Hello Wangyal,

There are OR and AND operator in the raster calculator. Try putting a
curved brackets around the expression.

In the following expression the cell will receive the value 100 if
incomras >= 2
or
disclasras >= 3
or
sanitatras != 0

(("incomras at 1" >= 2) OR ("disclasras at 1" >= 3) OR ("sanitatras at 1" != 0))*100

Hope it helped

Alexandre Neto
