[las_users] Problem Adding New Data to LAS

[John Schattel <john.schattel@xxxxxxxx>]

Hi All,

I am trying to add a dataset to a recently installed LAS and the script 
addXML.sh is complaining that "No Lat/Lon grids found." (see command 
line output below).  However, Ferret seems able to display the data just 
fine and there are latitude and longitude grids in the file (see ncdump 
of file below).  Is there anything I can do to get addXML.sh to work 
with this netCDF data or will I have to manually create the .xml file?

Regards,

John

Command line input and result:
-bash-2.05b$ /usr/local/las/bin/addXML.sh -n /data/dgom/hazmat.nc -v
Unknown unit: "sigma_level"
