prepair for Processing

Integrates prepair and pprepair tools into QGIS Processing framework.

prepair and pprepair tools are used to automatically repair polygons according to the OGC Simple Features / ISO19107 rules.

Note

Please note, that the plugin does not include prepair and pprepair tools. To use the plugin, you need to install these tools by yourself. Visit TU Delft GitHub page for installation instructions and source packages.

Usage

Once installed and enabled, prepair for Processing is registered as a Processing provider and its algorithms are added to the Processing toolbox under the “prepair” group.

You may need to configure the provider before using its tools. Open QGIS options from the menu “Settings → Options” and go to the “Processing” tab. Expand the “Providers” group and find “prepair” sub-group, here you will find all settings related to the prepair provider.

It is necessary to tell the plugin where to find prepair and pprepair executables. If these settings are not set, the plugin will assume that their locations were already added to the PATH environment variable and the tools are accessible by name. When done, save settings by pressing “OK”.

prepair algorithms can be used as any other Processing algorithm: in a standalone mode, as a batch processes, as a part of the models and scripts, using qgis_process command line tool. Please refer to the QGIS User Guide to learn how to use Processing tools.
