I am trying to speed up rendering of OS raster map tiles in QGIS.
The tiles are 1:10k Tiffs - about 130 of them.
When I attempt to build the VRT it says complete, then it shows up an error message:
Warning 6: gdalbuildvrt does not support rotated geo transforms.
The only settings I had on whilst creating the VRT were: resolution - highest Add to canvas after finishing
As you can see from the image some of the tiles were successful. I didn't have a problem with creating a VRT for 1:50k or 1:250k map tiles.
Any suggestions or advice on speeding up rendering of OS map tiles (such as pyramids) would be much appreciated.
