Does anyone know of any sources for free DEM and other remote sensing data in Germany?
I don´t think Europe is as open as the USA when it comes to free data!
The advantage of satellites is that they cover the entire globe. Sure Europe doesn't have the same data freedom as something sourced from NASA (the USA have the quaint notion that things paid for with public money should be public!), but those NASA satellites do still circle the entire planet.
There are a lot of possible sources of data, some free, some not:
- https://earth.esa.int/web/guest/data-access/catalogue-access/descw (Europe; ESA)
- http://www.esa.int/SPECIALS/Eduspace_EN/SEMX7BANJTF_0.html (If you're using it for teaching)
- http://library.oceanteacher.org/OTMediawiki/index.php/Remote_Sensing_Data_Gateway (a list of sites that contain Remote Sensing data)
For DEM data try the ASTER GDEM, which offers worldwirde free data in a 30m resolution. http://asterweb.jpl.nasa.gov/gdem.asp
For other Remote Sensing data, LANDSAT images might be an option, though resolution is only 15/30m
I actually found these datasets:
Probably a nice link collection for SRTM http://wiki.openstreetmap.org/wiki/SRTM
There is eg. http://www.dlr.de/en/desktopdefault.aspx/tabid-6840/117_read-30856/ etc
