Overlay Analysis of raster and polygon

[nurafiqah]

Hello,

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?

Use the Raster to Polygon tool

But I suspect that you don't have an integer raster, which you will have to deal with first

The input raster can have any cell size and must be a valid integer raster dataset.

Of course, it would be better if you just converted everything to raster and used Combine or other overlay tools in the spatial analyst extension if you have it
