Hi there,

Does NASADEM HGT v001 one-arcsecond (~30m) have stripe removal, vegetation offset removal and adaptive smoothing similar to the SRTM DEM-S product?

Many thanks
Jill

@jillianthonell The NASADEM User Guide does discuss how vegetation is handled but doesn't really go into the others, and the article "NASADEM GLOBAL ELEVATION MODEL: METHODS AND PROGRESS". The information provided is the extent of what is available for this data.

Kind regards,
Janice
