<p>Hint: use EPSG:4326 for the SRS of the .gti.fgb, because this is
the SRS of the tiles. The GTI driver isn't smart enough to figure
out that OGC:CRS84 ~= EPSG:4326, and thus a rather dummy
on-the-fly warping is done.<br>

<p>as you could also attach the XRES, YRES, BANDCOUNT,

probing one of the tiles.<br>
