ERDDAP can now hook into databases if they can make a view of the requisite data. 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 be sent by OpeNDAP, just as OpeNDAP sequences.

Folks,

We are wondering how we might get OPeNDAP access to an ArcSDE/ Geodatabase.

The EROS data center has gridded data (for example, the National

Elevation Database) stored in an Arc SDE Geodatabase, and they want to

have 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 connects

directly 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 Common

Data Model.    Could this work?

Thanks,
Rich
