GeoHash

GeoHash is an algorithm to encode and decode longitude and latitude. It's also an index method for GIS point. Using GeoHash code you can easily do searching in GIS applications such as "searching how many hotels around 1km" "clustering points in GIS map" and so on.

GeoHash是一种对经纬度进行编码的算法,也可以将其视为地图上点的索引,通过对地图上的点进行GeoHash编码(索引),可以方便GIS的很多其他应用,比如“查询周围1km内的酒店”,“对GIS地图上的点进行聚类”等,有了GeoHash编码可以很快的对范围内的点进行搜索查找。
