I am making a model in ModelBuilder and there is a problem with Raster calculator result. I have to rasters with 0 and 1 values, I want to know where do they intersect and make a new raster with value 1 in that places. In Raster calculator I put the expresion like: raster1 * raster2. The problem is that it returns empty raster (with 0 values only), but when I look at rasters I can clearly tell that they do intersect.
Does anyone know what the problem can be?
In order to do what you are trying to achieve you need to do a 2 step process:
This will give you a new raster with:
Values of 0 where both Raster1 and Raster2 have values of 0.
Values of 1 where one of Raster1 or Raster2 has a value of 1 and the other has a value of 0.
Values of 2 where both Raster1 or Raster2 have a value of 1.
The cells with a value of 2 are the ones you are interested in. But you said you want these to have a value of 1.
Depending on what you are trying to do, you might also need to reclassify the cells with a value of 1 to something else so that you can still differentiate between these and your new value 1 cells.
There was a problem with different resolutions :) The problem is solved
