Hi There,

I used the tool "Aspect" in spatial Analyst > Surface Analysis (standard pull down option)

I successfully created an aspect layer - but I would like to see the distribution of slopes.

I tried the following in raster calculator

([Aspect]*2 + 675 % 720) / 90

as proposed by Mr Huber here:

but it does'nt recognize my aspect layer. Also, there's no attribute table attached to it.

Any help would be much appreciated
