Hi, I was wondering if there exists any tool in the geotools/geoserver framework to do the following: Given two rasters A[x,y] and B[x,y] you want to output a single layer with colors C[x,y] = some_calculation(A[x,y], B[x,y]) which can be expressed in a simple CQL expression.
I thought of doing this with SLD. I considered the rasters could be put in different bands of the same raster file, because combining data from different layers does not seem possible in SLD, but it even that does not seem to make it possible. Unlike for vector tiles it does not seem possible to do calculations on the basis of bands like you can do with feature properties. You only have color maps. I also found this http://docs.geoserver.org/stable/en/user/styling/sld-extensions/rendering-transform.html But that does not include raster(s)-to-raster conversion. Wondering if there is something that I am missing.
