ASTER elevation data for the SAFE Project

These files contain processed data from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument, providing 1 arc second (~30 metre) resolution elevation data across the research areas used in the SAFE Project.

The ASTER data used in these datasets was collected by the NASA TERRA satellite. Although it is freely downloadable, ASTER data downloaded for a project should not be redistributed outside of that project. Accordingly, these data should only be used for research carried out at the SAFE Project.

These files combine four panes of ASTER data to cover the SAFE sampling region and carry out some simple geoprocessing to produce a single output files. Details of the geoprocessing can be found here: https://www.safeproject.net/dokuwiki/safe_gis/aster. In general, SRTM data is preferable for most use cases at SAFE, (see https://zenodo.org/record/3490488) but is provided here for comparison.
