I've searched for overlay analysis of steep slopes, soils, and land use class. The step requires to convert the slope to polygon. How to convert slope file to polygon? I have a slope.tif raster file. When I run the conversion raster to polygon, I keep getting the error message describing "010067 : Error in executing grid expression. There was a problem executing the map algebra expression.". Is there any step i missed?
Or is there any other step computed percentage of intersection between land use class and slope angle?
