Troubleshooting¶
Use OTB in old QGIS version (3.6 and less)¶
Warning
This method is deprecated. Please consider upgrading your QGIS version.
Since QGIS 3.8 and with 3.10 LTR version, the configuration of OTB Application is directly done in QGIS Provider (see above).
If you use an older version of QGIS (from 3.2 to 3.6), you need to install an additional plugin in order to use OTB applications. This plugin is available here with specific installation instructions.
Don’t use this plugin with QGIS 3.8 or higher. It might get messy if you upgrade your QGIS version and still have a previously installed plugin. Try to remove the old plugin before launching QGIS.
Issue tracking¶
If you encounter issues with integration of OTB application into QGIS, please fill an issue into the OTB issue tracker with qgis label.
