Internet.. SRTM data

Height data can be obtained by various sources. The main source of height data is SRTM data from NASA. But also other sources of SRTM data can be configured.

The actual url of the source of DEM is configured in the file 'internet.dat'

As the world wide SRTM data set is (too)big it is preferred to make a preselection depending on the area in which you want to make the analysis.

Also you have to pay attention to the way in which the data is approached on the web. All SRTM data from NASA is accessed through FTP. This might be causing problems when behind a fire wall or proxy. When choosing 'other' as SRTM source yo can select web access (http).
