QuadKey
Bing Maps uses a quadkey structure for their tiling scheme. Here is an overview of the concept http://msdn.microsoft.com/en-us/library/bb259689.aspx.
GeoHash
A geohash seems to be the more accepted representation in the open source word http://en.wikipedia.org/wiki/Geohash
So what I am wondering is if there are any trade offs between the two when being used as a spatial index. They are both rooted in the quadtree concept and carry it's pros and cons, but are there benefits to using one over the other?
