问题 My App uses openstreetmap files to show waypoint (or coordinates) on a map. Based on an Openstreet map file: how can I determine the shortest distance from a GPS coordinate to the (walking) path. Can I read an OSM (map) or .osm file ... to access the paths? 回答1: There are some misconceptions. First, the OSM file is not the map file. The OSM file can be used to create a format to make map rendering fast e.g. mapsforge format does this. With e.g. GraphHopper you import the OSM file like .pbf or
