Was this from the 1992 Mars Digital Terrain Model? With Mars Express
and Mars Reconnaisance Orbiter there are now better data available, no
global coverage though.

Dang ... there went my evening ;) There are lots of strips for HRSC of
Mars Express and a few local mosaics. Best resolution up to 50m/pixel.
Didn't yet find any dtm level data products for MRO. I spent most of
the time converting a vicar file to png - ImageMagick can do it but
returned an 8 bit png with alternating Hi/Lo bytes. It also interlaced
the left and right half of the image in odd/even lines.
