FYI...I use gdal contour a lot for placing Tactical Access Points in the field for our customers. Works really good in my opinion.

What grade of results can be got ? Antonio, I know a few people use it though it isn't heavily used. I'm pretty confident it does what it is supposed to do. Note that it does *not* attempt to simpilfy the results so you end up with very dense (points close together) contour lines with roughly one segment per pixel crossed. Also, be aware that the countours are just lines, and because they just end at edges of he raster or nodata areas, they aren't easy to form into polygons (if that is your goal).
