Before extracting the package, make sure that you have been through the First Steps page

Windows binary packages are available for Windows 10 or higher. They can be downloaded from otb download page .

Extract the zip archive and use one of the launchers, they contain all applications and their launchers (both command line and graphical launchers are provided):

  • otbenv.bat: A script to initialize the environment for OTB executables

  • bin: A folder containing application launchers (otbcli.bat) and the DLLs.

  • lib: A folder containing application DLLs.

  • include: A folder containing all the necessary headers to compile OTB based projects.

  • tool: A folder containing useful scripts to test the installation or to uninstall OTB libraries and headers while keeping all the dependencies.

If you want to use the otbcli launcher, you can initialize a command prompt with otbenv.bat.

The package can be used to compile other projects using OTB (binaries, libraries and headers are included). If you want to build OTB from source using this package, you should first uninstall the specific OTB files from the package to leave only the dependencies (what we call an XDK). You can do it using the supplied script tools/uninstall_otb.bat.

Python bindings

Since OTB 8.0.0, the bindings for Python 3.7 are distributed. Please note that using a different Python version may not be compatible with OTB wrappings. If the installation completes without issue, information relating to your Python bindings will be provided.

You must have Python numpy bindings installed in your system. They can be installed locally without admin rights as follows: “pip install –user numpy”. This is to give users the option to select their own existing Python installation rather than the one dibstributed by the OTB package.

By default, bindings for Python 3.7 will be enabled with the otbenv script.
