Network Topology QGIS 4 compatibility
QGIS 4 ready Active
Yes — Network Topology supports QGIS 4 (declared max version 4.99.0).
Toolkit to clean and build the topology of line networks (roads, rivers, pipelines, railways).
About
Adds a Processing provider with tools to clean and build the topology of a line network — roads, rivers, pipelines, railways: (1) Topology split — node the layer at every crossing (X) and endpoint-touch (T), extending dangles along their direction up to a tolerance; (2) Resolve dangles — directionally extend undershoots and trim overshoots; (3) Collapse pseudo-nodes — merge chains of lines through degree-2 nodes; (4) Connected components — label independent sub-networks; (5) Cluster extents — hull/bbox polygon per cluster; (6) Network nodes — points with degree and type. Output is single-part, geometry and attributes preserved. Built for QGIS 4.0 (Qt6 / PyQt6).
