James, So your handler *ingests* WCS and serves as OPeNDAP?
Yes. We have two pieces of code that involve WCS:1. A WCS Handler for Hyrax that serves WCS data sources using the DAP (you use a DAP client to read data and those data just happen to be accessed not from an HDF5, HDF4, NetCDF, RDB, ..., but from some WCS server. In other words this handler treats WCS like another 'file format'. One thing that I have done that is probably a disservice is to use the word 'file' too often. Hyrax serves data, without much regard for where it comes from. A WCS server is just another place you can find data.
2. A WCS Interface for Hyrax that takes DAP data sources and serves them using the WCS protocol. With this, you talk to Hyrax using the WCS protocol. In its infancy.

ERDDAP can also act as an OPeNDAP server. Some fiddling might be necessary to have the data seen as a grid. II not, it can still besent by OpeNDAP, just as OpeNDAP sequences.Yet another option is to use the WCS Gateway we developed for Hyrax. That is, there is a handler for Hyrax that is designed to serve WCS coverages.Email me for more info.

The EROS data center has gridded data (for example, the NationalElevation Database) stored in an Arc SDE Geodatabase, and they want tohave only one representation of the data (they don't want to create duplicate NetCDF files). They provide a OGC Web Coverage Service by which this data can be acquired, and we were wondering about the feasability of adding an OPeNDAP service, since there are currently quite a few OPeNDAP clients that would like to access this data. One option would be to build an I/O Service Provider that connectsdirectly to the Arc SDE. Has anyone attempted or thought about this?Another option that came to mind was the possibility of having the I/O Service Provider connect to WCS, using getCapablities and getCoverage to provide the syntactic metadata and actual data values to the CommonData Model. Could this work? Thanks, Rich -- Dr. Richard P. Signell (508) 457-2229 USGS, 384 Woods Hole Rd.
