Hi all,
splendid idea! Anybody who feels like working on WCS 2 support, feel free to
contact me or my group for any sort of explanations sought (I am the spec writer
of the coverages, admittedly). Note that the Coverage Implementation Schema
(CIS) 1.1 is out. Maybe this is a good starter:
http://external.opengeospatial.org/twiki_public/CoveragesDWG/WebHome .
"universe of optional extensions"
sounds like a fun software development project :)
In short, how well do you see WCS 2 / the coverage model fits GDAL data
model? It's not just raster anymore, right?
I guess the basic question is that do you think the existing WCS driver
is not an appropriate starting point?
In any case I don't have at this point any real funding / time for this
so I'd start incrementally and just reading the capabilities response
for coverage list is enough. But, I see the importance.
Ari
I' be
most happy to see GDAL WCS2-enabled!
cheers,
Peter

Hi Ari,
It seems to me that the WCS driver could benefit from some love.
That would be a good initiative!
In the wished feature list, I could add:
* improve test coverage, which is really low currently:

One issue we have for testing is the lack of stable & reliable servers.
One potential way of addressing this is to use a local HTTP server, like I did
recently with the /vsis3/ (and similar)
subsystems, where you can add stub endpoints. An extra advantage is that you
can also easily test error situations.
See

* WCS 2.0 support
