GPS Road Builder (RidgeSlide) QGIS 4 compatibility
QGIS 4 ready Active
Yes — GPS Road Builder (RidgeSlide) supports QGIS 4 (declared max version 4.99.0).
Reconstructs a connected road/path network (graph) from raw GPS tracks using the RidgeSlide density method
About
GPS Road Builder reconstructs a connected road/path-network graph from raw GPS tracks of any kind — forestry haul roads, logistics, sports (running, cycling), off-road, vessels, OSM traces and more. Its core is RidgeSlide — a Python/NumPy/Numba density method conceived, generalized, developed and completed by Alexander Kobyakov (building on Guo et al. 2020 and the Slide method, with his own corrections and additions): build a density surface, compact trajectories onto road ridges, extract a centerline skeleton, then weight, clean and connect the edges. A KDE mode is available for very sparse data. Designed for large inputs (tens of millions of points) with background processing that keeps the QGIS UI responsive. Heavy optional accelerators (scikit-image, numba) are installed on demand from a dialog — no silent auto-install. Interface in 12 languages: Russian, English, Chinese, Hindi, Spanish, Arabic, French, Portuguese, German, Indonesian, Thai and Vietnamese.
