Re: DODS/LAS

Charmaine,

You had a couple of questions that I'll rephrase and try to answer here:

1) How do I get the grid associated with a DODS file?

2) How can I use addXml.pl to add a DODS file?


1) The answer to 2) is one way of getting the answer to 1) but there is
another answer as well.  We have created a number of xml files for DODS
data we're aware of.  You can find a whole bunch of .xml, .jnl and .des
files in the following directories:

http://ferret.wrc.noaa.gov/LAS_xmlFiles/
http://ferret.wrc.noaa.gov/LAS_jnlFiles/
http://ferret.wrc.noaa.gov/LAS_desFiles/

2) If you have a recent version of addXml.pl (LAS v5.0 or higher) you
should be able to pass a DODS URL to it.  If you are in the directory
lasxml/server/ you can type:

../xml/perl/addXml.pl --out_inc ../xml/perl/template.xml
http://ferret.wrc.noaa.gov/cgi-bin/nph-nc/data/ocean_atlas_monthly.nc


This will create an "includable" xml file for you.  For more information
on xml includes see:

http://ferret.wrc.noaa.gov/Ferret/LAS/FAQ/xml_includes.html


I hope that helps.
