Folks, I sent an reply to Pauline but I'm not sure if she got. Pauline, I was wondering why WMS in the context of oceanography instead of LAS/Tredds/Ferret. WMS is quite restrictive; one looses vertical profiles, time series, etc. Efren A. Serra (Contractor) DeVine Consulting, Inc.

At present, the TDS is being run at the request of the IOOS Program Office to provide an unified interface to data via OpenDAP. (We are still largely using Hyrax at the moment). Our purpose is to not only serve aggregated oceanographic datasets for Alaska but feed these up through the IOOS backbone to the global ocean observing system (GOOS). I think there are probably several people in organizations on this list that can echo the same goals. We use OpenDAP in conjunction with modifications to the NetCDF, HDF and OPeNDAP driver in the GDAL library to make gridded data available via Mapserver and Matplotlib. There are some things the WMS in Mapserver cannot perform that we intercept and render through Matplotlib. Two examples are general contouring and vector plotting. This is accomplished by insertion of GDAL type markings (PROJ.4/WKT) in the global metadata for NetCDF and HDF served files. There are a lot of crazy things we do to increase capabilities of Mapserver, but I won't go into detail here. Something for consideration in the future is hopefully the GDAL driver can understand CF attributes to form the proper PROJ.4/WKT or we can just add the needed PROJ.4/WKT to the ncML. Or vice versa, PROJ.4/WKT -> CF > I wonder if there are many GIS users... Indeed. I estimate that the majority of analysis by agencies in Alaska is primarily ERSI/ArcGIS/ArcMAP based. The bulk of our data requests are to obtain datasets in GeoTIFF (WCS) for import into ESRI. However, scientists want access to gridded information via OPeNDAP or direct download (HTTP). The remaining requests have been for entire periods of record or large periods of record for station data: waves, temperature, wind, etc. Rob _______________________________________________ thredds mailing list thredds@xxxxxxxxxxxxxxxx For list information or to unsubscribe, visit: http://www.unidata.ucar.edu/mailing_lists/
