SSE — Space Syntax Engine
SSE (Space Syntax Engine): High-performance Compressed Sparse Row (CSR) Urban Street Network & Space Syntax Engine for QGIS (Angular/Metric/Topological Segment Analysis, Origin Step Depth, 16-Metric Axial Analysis, Natural Roads, Grade Separation, and 5-Step Adaptive OSM Cleaner).
SSE (Space Syntax Engine) is a high-performance street network replacement for UCL depthmapX v0.8.0 and Space Syntax Toolkit. Powered by contiguous NumPy/SciPy CSR Dual Graphs and GEOS STRtree O(N log N) spatial indexing, SSE computes multi-radius Universal Segment Analysis (Angular, Metric, and Topological Choice, Integration, NACH, NAIN, Total/Mean Depth, Node Count, Entropy, Control, Controllability), Origin Step Depth from points or lines, Exact depthmapX Directed-Segment Tulip-1024 / Continuous IEEE-754 modes, Bridge/Tunnel Grade Separation, 16-metric Axial Analysis (Hillier Diamond D_n RRA), Natural Roads Gestalt Strokes, Detailed CSV + Intelligibility/Synergy R² Table Export, and 5-Step Watertight OSM Network Cleaning.
