It includes void-filled DEM, Hydrologically Conditioned DEM, and Drainage (Flow) Direction at a 3 arc-second resolution. The data provides consistent geo-referenced datasets, including river networks, watershed boundaries, and flow accumulations. It's accessible through Google Earth Engine, and usable for commercial and non-commercial projects, but quality decreases above 60 degrees northern latitude.\n"]]
