I've got 2 raster maps (both with the same values: 0-100). After calculating the average I need to know how precise the map is. Is there any tool in QGis?
I try to explain my problem in another way:
I have 2 or maybe 3 percentaged raster maps. After putting together ((a+b+c)/3) I need to get a map that shows if the result map is statistically firm.
For instance: If all 3 maps have the same value in an area the result must be reliable/firm. If 2 maps have the same values and 1 map is totally different the result is a little bit unreliable. If 3 maps are totally different the result is unreliable.
I want to create a colored map (green, orange, red). I already have processed the average map!
