GraphHopper is a Java routing library and OpenStreetMap routing engine used to calculate optimal paths and driving directions. It provides a map matching engine for aligning GPS coordinate traces to road networks, a GTFS transit router for multi-modal travel, and a spatial analysis utility for isochrone generation. The project supports the creation of custom vehicle profiles and weighting logic to influence path calculations. It implements contraction hierarchies to accelerate pathfinding by reducing the search space between coordinates. The engine covers a broad range of geospatial capabili
