Hi Joe,
My minimal change is just to add the missing "RPC_DEM=srtm_12_05.tif" and
to know if it is enough to zero

helps with this, then I'm
happy to try it. I'll give that a look too.
thanks!

Hi,

that are stable enough might be challenging, so perhaps the issue is
related to that
A few other remarks:
- your gdalwarp command line refers to RPC_DEM_SRS and
RPC_DEM_MISSING_VALUE but doesn't include a RPC_DE
Hello,
I am attempting to implement georegistration through RPC. I have the following
information I've used to calibrate the RPC coefficients, using all terms for
numerator and denominator for both sample and line equations.
