Re: [thredds] future TDS WCS support for irregular/curvilinear grids?

Hi John,

TDS currently only supports WCS 1.0.0. The WCS 1.0.0 specification
itself does not support requesting or returning irregular/curvilinear
grids. I believe the same is true for WCS 1.1.0.

I don't belive this is necessarily the case for WCS 2.0. However, the
2.0 specification is written in the new core/extensions paradigm and I
don't believe the extensions necessary to request or return
irregular/curvilinear grids are yet written.

The TDS WCS implementation does not currently support regridding data.
So, currently one gets the data from the WCS in the same projection in
which the data is stored. The combination means the TDS WCS can only
serve regularly gridded data.
