Hi, is there a way to create new raster files of slope & aspect from a DEM? I know how to theme the data to display elevations, slope and aspect, but I am looking to actually create new data files. Just like how the Slope and Aspect tools in ArcGIS create new files. I'm exploring options because we don't have Spatial Analyst for our GIS but we do have Map 3D.
If you have a 3D TIN (many 3DFaces) in ACAD, I think that I have a Lisp/VLisp routine
which change the color of 3DFaces depending on the slope of each 3DFace ...
But you can't do more with ACAD, so as said antoniovinci,
you will have to switch to an other Mapping/GIS software ...

I think that's not the OP goal, sir.
He simply wants to create NEW rasters based on slope/aspect parameters:
1] Slope range goes from 0 to 90, where
2] Aspect range goes from 0 to 360 orientation degrees towards the North
Here's an example based on the volcano Etna dem (in Sicily island):
The best I can do with a nice routine "PF3D" from our best Frenchie Gilles / (gile)
which colorize 3DFaces depending of the slope !
Source must be AutoCAD 3DFaces ...
The Lisp routine runs on ACAD, MAP, CIVIL, AA, MEP, etc ...
With 3DOrbit and 3D different styles, we can get some interesting views ...
Yes Antonio's example is exactly what I'm after. Thanks for the help everyone. I will look into QGIS.
