Hi,
Thanks for the feedback. I am adding a note to the dem parameters of all
applications. I am not sure if we should support setting directly a
file, but anyway this is OSSIM behind the curtains which brings in this
folder thing ... Il will check if we can dot something to support both
folders (useful for SRTM complete database) and individual files.
Regards,
Julien

Hello,
A quick note to report on the fact that we identified the problem we
had, so that might help others as well: it is caused by the fact that
in the DEM directory there were other subdirectories and OTB was
selecting another tiff file as DEM from the subdirectories! We could
not understand the pattern, this is happening randomly in a couple of
images; it would be wise to include a notice in the OTB
Orthorectification description on the fact that the DEM directory
should be clean and not having other directories in there! It would be
even more appropriate in a future release to select the DEM file
instead of the DEM directory from my point of view.

Hello all and best wishes for this new year!
Is there any update on the Orthorectification issue? We are still
looking into this problem having tried possible combinations but
to no avail, we always get an illogical displacement when using
OTB. We would be very happy to use OTB for this reason and not a
COT software, if a solution will be found please let us know.
Best,
Dimitris

Hi Guillaume and other OTB users/experts
Please allow me to bring this thread up (I am a colleague of
Dimitris)
I know that the Xmas break is around the corner but we would
greatly appreciate if we could find a solution to this issue
so that we can move forward with our image processing.
Also, I have a follow up/related question: is there any
workaround to use OTB to orthorectify RapidEye images? (these
are over the same areas as the DG products mentioned in the
first post of Dimitris)
Thanking you in advance for your time and consideration!
& wishing happy holidays to the OTB community!,

Hello Guillaume,
Thanks for your concern. Yes the two products have the
same extent when I visualize them, these have been tasked
acquisitions over the same aoi. I have to mention though
that I stitch the tiles of the delivery together and I
subset them with the overarching aoi before the
orthorectification. Moreover, after atmospheric correction
I export from hdf to tif and I append metadata information
from the previous step, since all metadata are lost during
atmospheric correction.
When I use 'skipcarto' option with ReadImageInfo I don't
see the UTM projection info in none of the two images as
in the files attached. I also have noticed that the
'sensor' field is always empty in the info OTB is reading.
Any ideas?
I am running OTB version 5.0.0 on a Linux Debian 8.2
machine, GDAL version is 1.11.2, however the same issue
occurs when I am running on Windows (OTB via OSgeo4W).
Best,
Dimitris

Hi,
I was suspecting a missing SRTM tile but your 2
examples are on the same
area.
According to the ortho-ready projection information,
both images have
the same extent. Is is actually the case when you
visualize them ?
When you use the 'skipcarto' option with the
application ReadImageInfo,
do you still see the UTM projection info ?
What version of OTB are you using?
