Are we going to get a public DEM dataset better than SRTMv3 any time soon?

Hopefully the DLR will release the TanDEM-X dataset at some point in the future.

It could be the best global DEM if it's released, but now they're still charging for it. Maybe in a few years as new DLR satellites come on line.

Pretty cool! Looks like this has the same resolution 30 meter resolution as the global SRTM DEM, but with coverage of the whole globe. Looking forward to using this.

to be fair, between SRTM, ArcticDEM and REMA, you could get all but maybe some southern islands already?
