The DEM presented below (projected in equi-distance system hence ready for DEM analysis / flow modelling) was produced as a weighted average between three sources of global DEMs:

The processing steps are explained in detail via the Github repository on WorldGrids. Read more about global DEM data sources: DEM data sources (a review).
