[Qgis-developer] WCS and Raster improvements for QGIS

[Andreas Neumann]

 Hi,

 That sounds fantastic - looking forward to all these improvements!

 The WCS is one more OGC implementation that brings us closer to more 
 complete GDI support.

 Personally I am excited about the composer improvements. Together with 
 the serial printing initiative from the Atlas plugin we will get a quite 
 powerful map and report generation engine.

 I also like the requirement to have tests.

 Once this is all implemented one can see what could be exposed in QGIS 
 server and webclient.

 Thanks for the information,
 Andreas
