prepair for Processing 2.0

As part of my ongoing efforts to update and re-publish my QGIS plugins, I have just uploaded a new version of the prepair Processing provider.
Along with the fixes focused on Qt6 compatibility, this plugin also went through some refactoring driven by the changes in the latest versions of the prepair and pprepair tools and the availability of the native QGIS API to run external processes.
Just like with the Raster Transparency plugin, I realized I have never actually written about this plugin on the blog before. So, here is a quick overview.
prepair for Processing allows users to easily fix “broken” geometries using prepair and pprepair tools developed at TU Delft. It provides two algorithms, tailored to different cleaning goals:
- fixing single broken geometries (like self-intersections or dangling edges) according to OGC Simple Features/ISO 19107 rules.
- repairing a set of polygons to form a valid planar partition without unwanted gaps or overlaps.
