Denis,
if the view angle is off-nadir, you generally need to use the -to
RPC_DEM= option with a DEM covering the area of interest (and make sure
the values it contains are WGS 84 ellipsoidal elevations) to get
accurate results.

Hi,
I have a GeoTIF file and file with RPC information next to it (*.txt).
Is there a way to transform this raster to a normal geotiff without
displacement (with geotransform inside) or is it fundamentally impossible?
I've tried to achieve it with gdalwarp but in this case the result of
the transformation has about 5 meters (10 pixels) x-displacement (I
use QGIS to visualize it).
