这是API将很难获得，主要是由于数据的权限。

An API will be difficult to obtain, mostly due to data rights.

例如，谷歌地图Android版的部分原因有一堆它的API限制，是因为谷歌并不拥有所有需要，使他们的地图数据，并尽自己的导航。他们许可了一些数据，他们不得不忍受这些许可条款。

For example, part of the reason Google Maps for Android has a bunch of its API restrictions is because Google does not own all the data needed to make their maps and do their navigation. They license some of that data, and they have to live with those license terms.

***的答案长期可能是一些掠走的 OpenStreetMap的，因为这是人群来源和创意共享许可。不过，我不认为他们有一个解决方案，涵盖您的要求为present，至少在Android上。

The best answer long-term may be something made off of OpenStreetMap, since that's crowd-sourced and Creative Commons-licensed. However, I don't think they have a solution that covers your requirements at present, at least on Android.
