我想找到从A点到B点的所有可能路线(不仅是最短的路线)。 因此,我的问题是,在谷歌地图、雅虎地图等地是否有任何网络服务台(我使用 Java)。 确实如此。
这里是这一问题的另一个办法和解决办法:convert meters to Longration from any point
感谢您的答复。
我在谷歌地图指示Api中发现了这方面的一些内容:“alternatives(optional),如果真的确定,指示服务可提供不止一种应对途径。 注:提供路线替代物可增加服务器的响应时间 但不幸的是,当我把alternatives=true列入请求中时,我就不使用这一选择。 有了这样的选择——它更加灵活,但我发现,有人用<>中途>点anti。 (尽管它非常像“硬化”——我们具体说明我们将从街上穿过。) 任何人都尝试了alternatives=true!
我不赞成这样的事实,即“gogle”地图的道路是使用四舍五入的盒子,以便一味选择一只希望和一条通往另一条并不相同但却非常接近的道路,就像:
