The presentation at the link below is a demo I gave to Beverley's Intro GIS course today. It shows how to ingest a Web Coverage Service (WCS) into ArcGIS, perform some geoprocessing operations to extract information and export the data to KML format for display using the Google Maps API. I have the data for anyone interested in turning this into a lab for their course (you would probably want to skip the Google Maps API stuff). http://tinyurl.com/66cvkc Jarlath -- Jarlath O'Neil-Dunne Geospatial Analyst University of Vermont Spatial Analysis Laboratory www.uvm.edu/~joneildu
