我发现了一个很好的 API 来读取 Openstreetmap 数据；Mapscript.这是 MapServer 的一个接口，它能够读取 *.map 和 *.shp 文件.它能够使用空间索引，因此可能非常快.我在 40 毫秒内完成了世界海岸线形状文件的随机多边形查找(检查多边形是否与陆地相交).

I've found a great API for reading Openstreetmap data; Mapscript. This is an interface to MapServer, which is able to read *.map and *.shp files. It is able to use a spatial index and is therefore potentially extremely fast. I've done random polygon lookups (checking if a polygon intersects land) of the world coastline shape file in 40 ms.
