Hi Radim Nice to have a WCS client in QGIS!
If it goes via GDAL WCS driver, how does it work with Proxies (via libcurl?) Some poor users are sitting behind proxies, so it would be nice if the proxy settings from the options are applied to WCS client as well.

Thanks to financial support from T4E s.r.l http://www.t4e.it/ I could implement WCS support based on GDAL WCS driver. It is available here: https://github.com/blazek/Quantum-GIS branch wcs Because of WCS 1.1 bugs in GDAL (wrong axis order in bbox for latlong, no way to specify response CRS) and Mapserver (ignores RangeSubset) we have to stick with WCS 1.0 but capabilities parser for 1.1 is ready. It was written with possible use of common base classes for W*S in mind: new classes QgsOWSConnection, QgsOWSSourceSelect. Open issues: - How to pass the raster to GDAL Tools. Currently the XML string is created on the fly by GDAL provider and passed as a string to GDALOpen, there is no XML file which could be given to GDAL Tools. - How to specify an extent and resolution in GDAL Tools. - How to implement save a copy of WCS part Related: I believe that it could be better to organize OWS by servers instead of by services, especially in the browser. Instead of adding a new connection for each service, user could add just one generic OWS connection and available services would appear under that connection in the tree. I have implemented this in OWS meta provider. It reads and combines all defined WMS, WFS and WCS connections and displays all available layers (if there are few) or services under the connection: https://picasaweb.google.com/radim.blazek/OWS Radim _______________________________________________ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
