Orthorectification module

OTB Usage
1

Hi,
I have tested the Ortorectification module of Orfeotoolbox 9.0.0, but I have some problems with different images. In detail:

  1. for the projected Pleides/SPOT6 products (PRJ images) the output is equal to the input image, no SRTM (30m) contribution in the process. On the other hand, the ortorectification of projected GeoEye-1 and WorldView-3 images (2AS product) with SRTM 30m, adding the extended file name “?&skipcarto=true” generates ortorectified images.
  2. the ortorectification of QuickBird imagery (M2AS and M1BS products) does not function.
    I have undestrand that the extended file name “?&skipcarto=true” is necessary when the image is projected on average height, infact it is necessary when I want to ortorectified the P2AS products but for the M2AS products the usage does not solved the problem, module generates an error itk::ERROR: ImageToGenericRSOutputParameters(0xc37520): No information in the metadata, please set an image with non empty metadata.
    Same error is generated for the QuickBird M1BS products.

I would like to analise the source code to undestand the problems and to add the ortorectification of new sensors, but I gitlab I don’t find the ortorectification module, inside Core module.

Thank you in advance
Regards

Francesca

Hi Francesca,
The start point of the Orthorectification module is here Modules/Core/Applications/app/otbOrthoRectification.cxx · develop · Main Repositories / otb · GitLab .
Note the we support QuickBird images only in tif format (Supported file formats — Orfeo ToolBox 9.1.0 documentation).
Also try the develop version (Index of /packages/ci/latest) , maybe it solve your problem.
What is your complete output log ?

Best regards

Tristan

Dear Tristan,
thank you for the info regards the Ortorectification module, it requires a lot of study time :).
The QuickBird images used is in tif format.

Following the command and the complete output log for QB M1BS imagery:

Th errors are the same, I don’t have an error for the ortorectification of P1BS and P2AS.The problems seem be for the QuickBird Multispectral imagery.

Thank you
