Dear Ted,
The warning tells that there is a problem with sensor modelling, leading
to inaccurate results.
I would like to make to same resquest as in my previous mail :
- gdalinfo and otbcli_ReadImageInfo --keywordlist 1 of the image.
Probably your input image is an ortho-ready product, but I need to be
sure before giving you directions.
Regards,
Julien

Dears,
Given a WV2 scene and a set of image coordinates (rows and columns of
the image), I would like to transform the latter into lat/lon or UTM
coordinates. The scene is from Nairobi (Kenya) on the southern
hemisphere and geographic coordinates are something like
36.xxx/-1.xxxx. Input and output using
'otbcli_ConvertSensorToGeoPoint' is the following:
X:\>otbcli_ConvertSensorToGeoPoint -progress 1 -in
N:\G-Sextant\wv2\ps\12JAN01-M2AS_P002_toc_ps.tif -input.idx 18078
-input.idy 24199
WARNING ossimRpcModel::lineSampleHeightToWorld:
Max number of iterations reached in ground point solution. Results are
inaccurate.
WARNING ossimRpcModel::lineSampleHeightToWorld:
Max number of iterations reached in ground point solution. Results are
inaccurate.
Output parameters value:
output.idx: 37.50650406
output.idy: 47.56072617
output.town: Dmitriyevka
output.country: Ukraine
Besides the warnings which I do not understand, output coordinates and
location are completely wrong. The input image has been processed with
OTB already and includes a .geom file (attached). However I also tried
with the original WV2 scene. I would be grateful for any help.
Thanks,
Ted
