I can't explain the background here, but it seems deliberate. There's a comment before this request is made: " // It may happen (GeoServer) that extent reported in spatialDomain.Envelope is larger // than the coverage. Then if that larger BBOX is requested, the server returns // request BBOX intersected with coverage box scaled to requested WIDTH and HEIGHT. // GDAL WCS client does not suffer from this probably because it probably takes // extent from lonLatEnvelope (it probably does not calculate it from // spatialDomain.RectifiedGrid because calculated value is slightly different). // To get the true extent (it can also be smaller than real if reported Envelope is // than real smaller, but smaller is safer because data cannot be shifted) we make // request of the whole extent cut the extent from spatialDomain.Envelope if // necessary" getCache( 1, mCoverageExtent, 10, 10 ); Radim may know more and may be able to explain if this workaround is still necessary Nyall > > Is this supposed to go like this? > I reckon that (if the WCS data does not have overviews), loading the > whole dataset all the time is pretty intensive. > > Anybody more familiar with this can tell something about this? > > Regards, > > Richard Duivenvoorde > _______________________________________________ > QGIS-Developer mailing list > [email protected] > List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer > Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer _______________________________________________ QGIS-Developer mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
