It seems to me that the WCS driver could benefit from some love.
Is anybody working on it / planning to work on it?
I think simply a support for
gdalinfo WCS:...
to get a list of offered coverages would be useful to start with.

My personal opinion is that developing anything for WCS 1.x versions is
waste of time. WCS 2.x is much better standard and it is quite a lot
different than 1.x.

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:

suffered dearly - from the resources it needed to discover, to finding

The "tradition" in GDAL drivers such as GML, WFS is to strip AXIS from

Hi,
I've been having some issues getting the WCS driver to behave correctly.
However, I am new to GIS so it's very likely I'm doing something wrong.

projWin contains a negative longitude, the driver requests instead the
