An Ensemble Digital Terrain Model of the world at 30 m spatial resolution (EDTM30)
Description
Digital Terrain Model or Digital Land Surface Model is a digital raster map representing elevations of terrain / bare surface. NASA's SRTM DEM used to be one of the most famous environmental layers in early 2000's. In recent years a number of global public topography datasets at high spatial resolutions (30 m) have been released, from which Copernicus GLO-30 and ALOS AW3D30 are the two that can be considered new-generation elevation models. Too many versions of (basically the same) environmental data layer and too many landing pages can often confuse users and decrease the overall usability of such data. To simplify access and usability of such data we are building global Cloud-Optimized GeoTIFFs that are based on ensembling of multiple data sources, including national/regional datasets. Here is how you can access this data and contribute to the project.
