[Mapserver-users] Using Mapserver & GDAL to find elevation

[Ed McNierney]

John -

I guess what I'm asking is whether this is USGS NED elevation data or a
different elevation data set.

Not quite sure what the difference is, but the vender informed me that
it should be a close match to the "ArcInfo Binary Grid".  It is a format
created for a proprietary program.  Either way, the vendor told me he
would convert the data to something else for the cost of labor only.  So
yes, I need to use the same data files, but a different format is fine.
If that makes sense at all. :)

John -

Is this a proprietary data set, or is it a "commercial" data set that is
in a proprietary format?  That is, might it be possible to get the data
from a different source or in a different format?  Are you absolutely
committed to using these specific data files?

Hello all,

	I have a project where I need to be able to find the ground
elevation of coordinates on the fly.  The file format we have is
supposedly a proprietary format, but I believe it is close to the
"ArcInfo Binary Grid".  How would I go about finding the elevation using
mapscript (or some other way)?  Will mapserver even read this format (by
way of GDAL/OGR)?

Thanks!
