QGIS » QGIS Application

GDAL has WCS support. To be usable form QGIS, however, we need a button "Open WCS".
Notes from FrankW (thanks!):
Then the GUI dialog could write the
WCS control file. Note that the only two things required in the control file are the Service URL and the coverage name. But to offer the user a list of coverage names you would need to actually fetch the capabilities document - something I felt was out of scope for GDAL.

PS. The wcs service file does not actually need to be written to disk if you want to avoid problems with temporary files. But doing so is good in that it is used to cache details about the coverage for future use, and it gives the end user a file where they can tweak some of the odder parameters.
