在OSM Magsforge(离线)地图上的点和路径之间的最短距离 [英] Shortest distance between point and path in OSM Magsforge (offline) map
问题描述
在一个App我加载OSM / Mapsforge离线地图。
In an App I load an OSM / Mapsforge offline map.
我如何确定一个坐标(航点)之间,并在Mapsforge文件中的最短距离最近的路径?我得到的信息是Mapsforge(离线)地图。
How can I determine the shortest distance between a coordinate (waypoint) and the nearest path in that Mapsforge file? The info I got is the Mapsforge (offline) map.
对不起 - 重新发布此 - 我现在知道我必须使用Graphhopper标签
Sorry - to repost this - I now know I have to use the "Graphhopper" tag!
推荐答案
通过mapsforge你不能做到这一点。你必须使用一个路由库像graphhopper之一。在这里看到如何使用它: http://graphhopper.com/#developers 。
With mapsforge you cannot do this. You have to use a routing library like graphhopper is one. See here how to use it: http://graphhopper.com/#developers.
但也有其他离线和在线的路由器也是如此。这里有一个看看: http://wiki.openstreetmap.org/wiki/Routing/offline_routers这里 http://wiki.openstreetmap.org/wiki/Routing
But there are other offline and online routers as well. Have a look here: http://wiki.openstreetmap.org/wiki/Routing/offline_routers and here http://wiki.openstreetmap.org/wiki/Routing
