I just had a small question in regards to Digital Elevation Modeling. Currently I am using ASTER GDEM files in order to complete my work, however I was just wondering if there was a way I could complete Digital Elevation Analysis without having to download individual files and could do this on a more regional/nationwide scale?
Search yur DEM in the free USGS server. You can downoload small areas at high resolution or big areas at small resolution, like the ASTER GDEM. Also the last version of the SRTM DEM is very good and have resolution: 90 meters
