FYI, I just spotted this undated announcement on the USGS Seamless page:
"(SRTM 'Finished') The SRTM 'finished' elevation dataset contains a half
pixel shift. This is currently in process of being corrected. Caution
should be used when doing analysis with this dataset."
I see no mention or further details on the JPL site.

adding 3DFACE support to v.in.dxf!
