If you decide to add an elevation metadata keyword for things you generate let
us know and I at least will follow suit. ;-)

Hi Nyall,
you didn't miss anything. There's no standardized metadata to figure out
if a band is DEM. A few drivers (at least USGSDEM, DTED, SRTMHGT, BLX,
BT, Leveller, Terragen, SIGDEM, HF2) convey exclusively height related
data, but most others can convey anything, often without a
distincti
read from a global dem via the warper and do a correlation test?

Hi list,
I'm looking for any tips on potential approaches I could use to
automagically guess that a particular band from a data source
represents an elevation surface.
I haven't been able to find any common metadata components in the
files I've investigated which could help indicate this, but may
