We don't have any new interaces yet, neither on PostGrid or NetCDF side.
PostGrid come with a bunch of interfaces, but I consider them as internal
working (this is an other reason why this project was not developped on
Geotools), so really you can ignore everything in this project (as far as API
exposed to developers is concerned).
NetCDF is developped on top of javax.imageio API, even for the 3D part (I'm
using the standard "band select" API for that) so there is no new API there
neither. There is some convenience tools for ImageReader developers, but anyone
can ignore them.
The only thing really new is a schema proposal for geographic metadata. This is
more a XML schema than a Java API. This part is standardized in "GML in JPEG
2000" OGC specification (but still I need to align it better with the standard).
We will need to revisit the GridCoverage2DReader API, but we have not yet
reached this part. So yes we would like to work on a GridCoverageExchange
replacement, but we have not started this work yet.
So in summary:
* You can ignore completly the "postgrid" project. This is an experimental
implementation. It doesn't propose any API at this stage, and I do not
expect it to become an API in any foreseable future (the API would be
whatever will replace GridCoverageExchange; the PostGrid API is just
implementation details).
* The only thing new in "coverageio" and "coverageio-netcdf" unsupported
modules at this time is the XML schema for geographic metadata in rasters,
in the spirit of "GML in JPEG 2000" OGC specification. There is no new
Java API at this time. There is a bunch of support classes for
implementors, but anyone is free to ignore them.
* I already posted an email about this "geographic metadata" stuff a
few weeks ago and got no comments. Prolably my email didn't gave
enough details. I will post an other one soon.
