WCS and Projections

[John Caron]

Hi Pauline:

The paper is a few years old, the TDS WCS service is ok as a production system IMO, within the limits that the paper outlines.

TDS is not supporting coordinate transformations because that requires regridding, which is non trivial for data (not pictures). Ideally, some other service would provide that, written by someone with expertise with that. Balaji's proposal to CF may solve the problem in a general way, but we havent had time to explore that in any depth.
