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

[Craig de Stigter]

Hi folks

I'm working on converting an existing VRT mosaic pipeline to use GTI to
improve its scalability with huge layers.

A problem is that our individual raster tiles may have projections with
subtly varying WKT, since they were often produced by customers using
different tooling and in different places. The WKT in the tiles may even be
altogether incorrect or missing (even though they're actually all the same
projection as the GTI file itself).

With VRT this was not a problem since the VRT file didn't support
reprojection and just overrode the projection of its tiles. But with GTI I
think the driver is unnecessarily passing everything through the warp
kernel.

Is there a way to override the projection of the source tiles when using
the GTI driver?
