Geohash library that focuses on rectangular areas for fast database lookups.
geohash.rect(lat,lng,distance,precision)
Generates geohashes of a given precision around a supplied point (lat and lng) as determined by distance.
geohash.area(fn,precision)
Returns a list of geohashes for a given precision (i.e. length) that cover a particular area. The supplied function should recursively estimate whether a supplied geohash touches the area of interest. This function should return 2 if the particular geohash is completely within the area boundaries being tesed.
geohash.encode(lat,lng,precision)
Generates a geohash for a position with a given precision
geohash.decode(hash)
Decodes a given geohash to a rectangle (left,top,right,bottom) with midpoint defined as lat / lng
geohash.distance(start,end)
Both start and end should include properties lat and lng. Function returns the distance between the two points as number of miles
