Aster Global Digital Elevation Model
The Aster Global Digital Elevation Model is a joint US and Japanese effort. It is based on data from sensors on board on the NASA Terra satellite launched in 1999. The first release of the Aster GDEM dataset was in June 2009. It has a 30 m resolution with a 99% global coverage. However, the current version of the dataset is marked as ‘research grade’, and is reported to contain serious artifacts and spikes. Currently, the dataset is not included with WindPRO, but you may choose to manually download the source DEM’s and then import it into WindPRO.
