Hi all, Just a minor correction. The second URL below, for our prototype TDS, should be http://motherlode.ucar.edu:8080/thredds/catalog.html Ethan Ben Domenico wrote: > Hi George, > > If I understand your suggestion, something like our THREDDS Data Server > which includes a WCS interface to many different types of environmental > data would be appropriate. > > The TDS homepage is at: > > http://www.unidata.ucar.edu/projects/THREDDS/tech/TDS.html > <http://www.unidata.ucar.edu/projects/THREDDS/tech/TDS.html> > > We have our own prototype TDS at Unidata serving a wide variety of > real-time weather data.
