Osm-Routing-App

Android App for offline routing with OpenStreetMap. Created during an exercise at the University of Stuttgart http://www.uni-stuttgart.de/. It uses a partitioned routing graph and an optimized A* algorithm to run on mobile devices with scarce main memory while achieving good routing performance.

Uses Mapsforge https://github.com/mapsforge/mapsforge for map disaplay. Uses OpenStreetMap data to generate routing graphs.

AndroMapView

Java App for offline map display and routing.

Prerequisites

  • For display needs a mapsforge file at SD card (ExternalStorageDirectory) osm/mapsforge/display.map
  • For routing needs OSM road network chunks, called "grids" at SD card (ExternalStorageDirectory) osm/routing_grids. These can be generated using OsmConversionPipeline.

OsmConversionPipeline

Java application to convert OpenStreetMap data (osm.pbf) to AndroMapViews format. Uses sevaral steps to simplify the routing graph and finally separate it into chunks.
