TopoNodos QGIS 4 compatibility
Not QGIS 4 ready Active
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
Detect elevation inflection nodes and split pipe networks using DEM/DSM terrain rasters.
About
TopoNodos is a QGIS plugin for terrain-aware pipe network analysis. It samples DEM/DSM elevation rasters along water, sewer, drainage, and utility lines; detects topographic inflection nodes; creates complete start/end and inflection node layers; and splits lines while preserving original geometry. The plugin supports different input CRSs, an explicit projected work CRS, independent output CRSs, multipart line processing, raster-based node refinement, and duplicate node prevention.
