RE: point_spacing must be even?

Excellent.  We're in business.

Now, how I can look at the half-day I spent trying to resolve this?  Was
it (a) a complete and embarrassing waste of time, or (b) worth every
penny since I have the most COARDS-compliant netCDF known to man.

Thanks for the tip.

The error looks more like Ferret is having trouble finding or opening
file.  The point_spacing attribute shouldn't be a problem and wouldn't
generate this error.  Please check the permissions on this file (it
needs to
be readable by the web server user) and make sure that the
las/server/Ferret_config.pl has the appropriate environment variables to
Ferret find the file.
