I am currently working on a planning system for cycling, walking, sailing, etc. It is based on both a fixed network and a full OSM network. There is a web app for the planning of routes and a mobile app for the navigation of these routes.
Among others i have used the following tools: postgresql, postgis, pgrouting, QGIS, Open Jump, Google Maps, Osmdroid, leaflet.
Atm i am interested in fast routing solutions that allow me to route realtime on larger OSM datasets (>100K ways).

Help choosing a suitable routing engine Karussell, thank you for the info! I had already found OSRM, but GraphHopper is new for me. |

How can I snap lines in PostGIS? A weird thing is that ST_RemovePoint and ST_AddPoint are 0 indexed but ST_PointN is 1 indexed. |

How can I snap lines in PostGIS? simplexia - I used St_RemovePoint and ST_AddPoint as a way to replace a vertex (as I couldn't find the ST_ReplacePoint you mentioned). It worked. If you upgrade your comment to an answer I will accept it as the answer I was looking for. |

How can I snap 2 lines in QGIS so the st_distance between them is 0? I do the tests in PostGIS. |

Why is pgrouting astar not consistent? Checking the boost library the default heuristic function seems to be (dx+dy)/2. |

Why is pgrouting astar not consistent? Could it be that the order i feed astar the rows determines which vertices he will examine first. Anticlockwise (see image) all vertices will be closer by than the first one clockwise. And once he discovers the target he doesn't test other shorter routes anymore? |

Why is pgrouting astar not consistent? Any idea why that works? The difference i see is that the numbers in EPSG4326 are much smaller. |

Why is pgrouting astar not consistent? I am using EPSG:28992 (RDNEW). This is in meters. Let me try 4326. If i transform the x's and y's into 4326 before astar it gives the correct answer. |
