WorldDEM vs SRTM
Has anyone compared using the newer WorldDEM dataset for SDR erosion model versus using free 30 meter SRTM data? It is nice to have free SRTM data, but I know it is not ideal for this use. On the other hand, WorldDEM is rather expensive if modelling a large area. So I would like to know if it is superior and precisely why. That would also help in arguing for funding to purchase the dataset. Thanks.
