[gdal-dev] GTI: override SRS of source tiles (disable reprojection)

[Craig de Stigter]

Thanks for the replies. Using a FGB tile index without GTI/VRT
unfortunately doesn't solve the problem since at some point the caller will
still have to (pointlessly) transform the tiles, but thanks for the
suggestion anyway.

The VRT connection string sounds ideal; I hadn't seen that before. I had
been considering adding VRTs for each tile but tons of XML files lying
around wasn't very appealing, so it's great that we can do that without the
extra files!

Thanks
Craig
