Second: Merge your GeoTIFF into one file, that way there won't be internal edges. Third: smooth the DEM gis.stackexchange.com/questions/12833/smoothing-dem-using-grass then make your contours. This assumes you're only dealing with a relatively small area, for a larger area you'll hit the 2 GiB shapefile size limit depending on the ruggedness of the terrain and the contour interval. | |
