Re: 20010313: LAS/Ferret data load question

[Joe Sirott <sirott@xxxxxxxxxx>]

Hi Billy,

LAS questions should be sent to las_users@ferret.wrc.noaa.gov; the Unidata folks can answer DODS or netCDF questions.

Have you had a chance to look at the updated documentation that went out with version 5 of LAS? It's in README.html in the LAS tarball; it's also available online at  http://ferret.wrc.noaa.gov/Ferret/LAS/README.html
The architecture section describes how XML files are used in LAS, and the Understanding/modifying the XML configuration file section describes the syntax of a LAS XML configuration file.

You only have to worry about the XML configuration file when you add or remove datasets. Datasets are added by adding new tags to the XML configuration file, as described in the LAS documentation. Once you have changed the XML file, you need to run the genLas2.pl program. This program generates the user interface (which will be downloaded to the user's Web browser), and stores the XML in a MySQL database.

Hi Billy,

This is a LAS question more than DODS. So I'm CCing the LAS/Ferret folks
out at PMEL. Hopefully, they will be able to help you out.
