Classes

Class	Description
GpkgRoadGraphPreprocessor	Reads a Geofabrik-style OpenStreetMap GPKG snapshot of a region's road network and writes the largest strongly-connected component as a pair of gzipped CSV files that OsmCsvGraphLoader loads back into a Graph<Integer, ...>.
GpkgRoadGraphPreprocessor.Result	Summary statistics from a preprocessor run.
HaversineHeuristic<V>	Great-circle (Haversine) admissible heuristic for A* over geographic graphs.
OsmCoordinatesReader	Reads a headerless node_id,lat,lon CSV (the companion file produced by GpkgRoadGraphPreprocessor) into a Map<Integer, double[]> keyed by node id, with each value an array {lat, lon} in decimal degrees.
OsmCsvGraphLoader	Loads a headerless weighted edge-list CSV (the format produced by GpkgRoadGraphPreprocessor) into a target Graph.
