Choosing Cataloged Data

The General->Catalogs chooser shows THREDDS catalogs of data holdings on remote data servers (typically TDS or OPeNDAP) and provides access to remote Web Map Server (WMS) image servers. McIDAS-V provides a link to an initial default catalog, idvcatalog.xml, which should appear in the Catalog menu. If not you can directly enter the URL of the catalog: http://www.unidata.ucar.edu/georesources/idvcatalog.xml.

This URL links to a catalog of real time model data, a collection of county level shapefiles for roads and hydrography features, and a collection of useful Web Map Servers. For more information on using this chooser to display grid data, see Getting Started - Displaying Gridded Data.

The tree view on the left shows the different image layers available. You can select one image or use Ctrl+click to select multiple images. The map on the right plots a red box around the bounding area of the particular item selected.

Data files that are imported through the WMS Servers must contain gridded data. Also, the NetCDF-Java Common Data Model must be able to identify the coordinate system used.
