The sources available are: ASTER, COPDEM30, COPDEM90, AW3D30, DEM3, SRTM, NASADEM, MAPZEN and TanDEM-X.
another location where TanDEM-X has artifacts
the other DEMS also agree quite poorly
obvious smoothing artefact in SRTM
the smoothing artefacts are gone in NASADEM and probably replaced with ASTER data
NASADEM and SRTM are quite different here
NASADEM still has a wired feature in the northwest corner which is also present in SRTM
