fetching netcdf from web service

Rob Fuller
Hi,

I was hoping to expose some ocean data as WMS using mapserver, where the netcdf data is fetched on demand from the erddap server.

The gdalinfo command appears to show something useful, however the corresponding ogrinfo command doesn't, and neither have I been able to come up with a mapfile to see any kind of data fetched from erddap and rendered.

Has anyone done this or can you offer any tips?

Thanks,
Rob.
