Whoops! I guess I missed that very simple piece of information! Sorry
about that.
To use SRTM data with QGIS, I believe you'll need to generate georeferenced
images from the SRTM terrain model, or download such imagery. GRASS & GMT can
generate such imagery from the SRTM model. QGIS does not have the analytical
capabilities to do this (yet).
As said elsewhere on the list, I don't really need to be able to see the
data as 3D (except that it will impress my advisors), and I don't plan
to try and print anything other than flat images in the final product.
I presume that if I have the information in the file, generated using
one of the methods above, that I can still use the elevation data in
calculations of things like visibility or slope via qGIS? Or am I
really better off using GRASS by itself?
Thank you all very much for your help and patience.
