My problem is related with Global DEM to Slope calculation. The slope tool works when raster is projected or the map is projected where the raster is added. And also, if the raster and map both are not projected, slope tool runs well but may be the result is not perfect.
Problem is when I run the slope tool from my c# code and pass the raster layer to slope tool. Only when the raster is projected, the tool runs well otherwise reports a crash. In fact when the map is projected, tool reports a crash.
There I could not find a way that I pass the map projection system to the tool. At the same time, when I pass a Z-factor value, why does it matter if the raster data is projected or not?
