I have two raster datasets. One raster dataset shows population density, with the range of population density values given a score from 1 to 10. The score is entered into a separate column.
The second raster dataset is average income. The range of average income values have been given a score from 1 to 10. The score is entered into a separate column.
I would like to integrate these two raster datasets and create a third. I would like the third raster dataset to display the sum of the first two raster dataset scores. So the third raster dataset will have values ranging from 2 to 20.
I am using ArcMap 10.3 with the spatial analyst extension.
Edit: The context is conservation planning. We have a number of layers that we would like to integrate to develop an overall "cost score". The individual input layers have been scored so that a value of 10 indicates highly modified or impacted / not worth protecting. A lower score indicates the opposite. This will feed into a larger analysis involving species' distribution, endemicity, etc.
