I hate to do this but I'm in a pinch. I need a slope analysis done on a DEM I have. I don't have Spatial Analyst or 3D Analyst for my ArcView license so I don't know how to do it. Would anyone be willing to run a quick slope analysis of a DEM for me? Or, alternatively, does anyone know of a free software program that could run a slope analysis for me without too much pain and suffering (i.e. lengthy or complicated installation process)? Thanks in advance for your help. If you'd be willing to run the analysis for me, send me a PM and I can email you the DEM. Thanks again.

I would suggest SAGA software. User interface is a bit odd but it's very powerfull software (and free).

Is SAGA software a Linux package or Windows? I'm running Windows XP.

There are Windows binaries for SAGA. Their home page might be more helpful than the SourceForge link.

I've found SAGA to be inscrutable, but I admit I didn't put much effort into making it work. It does appear to be pretty powerful, but figuring out which knobs to turn and which buttons to push is a challenge.

I use SAGA for some map projections that ArcGIS doesn't support, but I am not overly impressed - the user interface and interaction paradigm is quite different and it was not all that stable on my old Windows XP machine - haven't tried on my new workstation
