[THREDDS #UCC-670485]: interfacing with ArcGIS

What THREDDS server are you using, our motherlode server 

Depending on the server and the datasets you want to access, you may be able to 
use the "netCDF Subset" service which includes a web form front end. It 
provides a mechanism for downloading a subset of a TDS served dataset as a 
netCDF file. It isn't available for all datasets but on motherlode it is 
available for most of the model data. Here's an example: from the following 
dataset link:


select the "NetcdfSubset" Access link:


_From there, you can select variables, time range, and geospatial extent of 
interest and get a netCDF file of just the data that matches your selection. 
ArcGIS, as of version 9.2, can read netCDF files (there are some limitations on 
which netCDF files it can read but it should be able to read all the files from 
the model data).

I believe ArgGIS 9.3 (which is just out in Beta) can access data through WCS 
servers. It does not however have an interface to THREDDS catalogs.

Hope this is helpful. Let me know if you have further questions.
