OTB Release 9.0.0

Posted on by Thibaut Romain

Dear OTB community,

We are happy to announce that OTB version 9.0.0 has been released!

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

The Docker image is available :
docker pull orfeotoolbox/otb:9.0.0

It is also possible to checkout the branch with git:

git clone https://gitlab.orfeo-toolbox.org/orfeotoolbox/otb.git OTB -b release-9.0

The documentation for OTB 9.0.0 can be found here .

This major version introduce a whole new packaging system entirely made with CMake / CPack, to make the toolbox more modular. You still have the possibility to have a full package for Linux and Windows, but for those who want to install only a part of the toolbox it is now possible. The modules list is available in the cookbook with their associated applications. All the packages are now in tar.gz and the installation is movable unlike OTB < 9.

This release also drops the GUI part which was heavy and redundant with QGIS which is now the official visualization tool. The version 9.0 does not include Monteverdi or Mapla. This led to a reduction of 80Mo in the package size.

This version also marks the drop of MacOS support, but users on Apple Silicon chips can use the Docker image to continue using OTB.

For QGis users, the otb plugin is not packaged since version 3.36 (see https://qgis.org/en/site/forusers/visualchangelog336/index.html#breaking-changes ). For the moment, you can only use otb with QGis version < 3.36. The otb team is working to build and publish the plugin on QGis catalog, it will be available in the next few weeks. Track the following issue for updates https://gitlab.orfeo-toolbox.org/orfeotoolbox/otb/-/issues/2379 .

This version also contains some performance improvement on the DEMHandler and SARMetadata.

The Release Note for this final build is available

To download the packages one by one for a modular installation, you can download them here and follow the instructions in the cookbook .
