Daten:
- Höhenmodell SRTM (90x90m bzw. 30x30m)
- "On November 20, 2014, the LP DAAC released additional tiles in the NASA SRTM Version 3.0 Global 1 arc second dataset (SRTMGL1), to include coverage over Europe, North America, and South America. This coincides with the newly processed areas released by the USGS on November 17th, 2014, available through EarthExplorer." by lpdaac.usgs.gov.
- SRTM4 / SRTM3: v4 (SRTM v.2 Infos, von cgiar.org aufbereitet V.3)
- Höhenmodell ASTER GDEM v.2 Released October 2011 (30x30m Pixel, Genauigkeit effektiv 70m):
- http://www.ersdac.or.jp/GDEM/E/4.html (Download: JP mirror, or better US mirror)
- Still a lot of artifacts in ASTER GDEM 2 data. Seems to be more noisy compared to SRTM 3 data, especially in more or less flat areas and artifacts in areas of rivers and lakes (see also [5]).
