Hi Manu,

This is a GDAL error.  In the case of png's they don't actually have
any geo-referencing info like GeoTiff's have, so perhaps this is a
contribution.

Try running the GDAL commands for re-projecting the data, I'm afraid I
can't remember them off hand.  Another thing you could try is to use
GDAL to convert to a GeoTiff and add the geo ref data in.

Hello,

I'm trying to build an high definition model with osgdem but I get this
error when trying to add texture data :

ERROR 1: Unable to compute a transformation between pixel/line
and georeferenced coordinates for ../128K_BMNG/level5/tx_0_1.png.
There is no affine transformation and no GCPs.
Failed to reproject../128K_BMNG/level5/tx_0_1.png

any idea where this could be coming from ?

Manu.
