Topoliner QGIS 4 compatibility

QGIS 4 ready Active

Yes — Topoliner supports QGIS 4 (declared max version 4.99.0).

Topology check, cleanup and coverage model for polygon and line layers: snapping, missing nodes, dangles and overshoots, assembly check, topology-preserving simplification

About

Brings polygon coverages into order. Finds topology violations and separates certain debris from cases that may carry meaning: the first group is fixed silently, the second is only reported and never changed automatically. Snaps neighbouring borders to an exact match without moving any vertex further than the tolerance, inserts missing nodes without changing shape or area at all, checks whether groups of objects assemble into one body, and simplifies while keeping shared borders shared. Replaces the manual routine of snapping a layer to itself followed by a dissolve without attributes. All tools live in the Processing panel and work in models and in batch mode. Interface in English and Russian. Tested on QGIS 3.16 through 4.0. A companion to the Isoliner kriging and contouring toolset (plugins.qgis.org/plugins/grid_isolines) and to Isoliner3D, a standalone 3D viewer for geological surfaces and bodies (plugins.qgis.org/plugins/isoliner3d). Developed with the support of Inform++ LLC (www.informpp.ru).
