Reworking of a simple centerline migration model that simulates meander bend cutoff distributions with statistical tests for spatiotemporal clustering

Segment and measure binary branching shapes — centerlines, hierarchical space partitioning, and width fields for rivers, valleys, glaciers

AutoLISP tool that automatically generates wall centerlines from 2D architectural floor plans in AutoCAD. Handles T/L/cross junctions, variable wall thickness, and drawing imperfections.

QGIS plugin that reconstructs a connected road/path network (a graph) from raw GPS tracks, powered by RidgeSlide — a density-ridge trajectory-consolidation method (Python/NumPy/Numba). Works for forestry, logistics, running/cycling, off-road, vessels (AIS) and OpenStreetMap traces. QGIS 3.x. Plugin GPLv3; the RidgeSlide core is MIT.
