<p>Denis,</p>
<p>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.</p>

</div>
<div>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?</div>
<div>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).</div>
