Hi,
For the record, we (actually my student!) have written a script which uses
ReadImageInfo to dump the GCPs and create the tie points file for
GenerateRPCSensorModel and after that, we use the OrthoRectification
application.
It seems to work (we have some artifacts in the generated image, but we are
looking at that).
However, I am still wondering why the OrthoRectification application is not
using the metadata in the initial image? I understand that what we have done
can be useful if the image to be orthorectified does not have the GCPs and they
are available elsewhere, but all the information is contained in our initial
image:
GCP Projection =
GEOGCS["WGS 84",
DATUM["WGS_1984",
SPHEROID["unnamed",6378137,298.257223560493,
AUTHORITY["EPSG","4326"]],
AUTHORITY["EPSG","6326"]],
PRIMEM["Greenwich",0],
UNIT["degree",0.0174532925199433],
AUTHORITY["EPSG","4326"]]
GCP[ 0]: Id=1, Info=
(0,0) -> (3.35838036356165,44.0387571612464,573.503620014526)
Furthermore, the OrthoRectification application has an option -opt.rpc. What is
the purpose of this?
Thank you.
