OTB release 8.0.0

We are happy to announce that OTB 8.0.0 has been released!

Ready to use binary packages are available on the package page of the website:

It is also possible to checkout the branch with git:

git clone https://gitlab.orfeo-toolbox.org/orfeotoolbox/otb.git OTB -b release-8.0

The documentation for OTB 8.0.0 can be found here.

This major version brings a lot of refactoring that aims at removing the dependency to OSSIM. A release note describing what to expect from this new version of OTB is available in the documentation . In particular, this version introduces:

  • A new Metadata framework. The ossim keywordlist have been replaced by the otbImageMetadata class.
  • A new organization for the Sensor Models (RPC and SAR models)
  • A new way to handle DEM

For developers working on remote modules, a migration guide is available.

It also comes with an unanticipated break in the API :warning:: thanks to Nicolas Narçon and Remi Cresson who proposed an improvement in the ComputeImageStatistics application, the -xml parameter becomes -out.xml. This change was not announced in the previous version of OTB, don’t forget to update your scripts if you use this application. The reason of this change is the arrival of 4 new output parameters: -out.mean, -out.std, -out.min and -out.max. You will notice that the application is now able to compute the min and max of the image.

The full changelog can be accessed here . We welcome your feedback and requests on OTB’s GitLab and if you find a bug, please report it !

Thanks to everyone who helped during the release process,
the OTB team
