可能没有简单的方法,要么您必须收集这些值(地图)并将其与当前的 GPS 位置进行比较,要么您可以从处理此问题的公司之一购买。
Probably there is no simple way, either you have to make a collection (map) with the values and compare it with current GPS position or you can buy from one of the companies dealing with this.
NAVTEQ 似乎是一家提供此类数据的信誉良好的公司。开发者页面(之前链接)应该为您提供更多相关信息。它不太可能是免费的;你必须联系他们才能达成某种许可协议。
NAVTEQ seems to be one reputable company that serves up this sort of data. The developer page (linked previously) should give you more information on this. It's not likely to be free; you'd have to contact them to work out a licensing deal of some sort.
