The Plan

My geohashing alert2016-01-13 15:28-system at 123k.org shows the current geohash for my home graticule. The plan is to the nearest route which passes by.

Finding Something

As mentioned earlier I have all points i ever visited in a collection. This collection holds a geospatial index. Therefore I can issue mongo queries with the $nearSphere command. This command finds the first points from a given location.

So this just works. But what about other routes which may also be nice and just around the corner? We can select many points around the hash point and check which routes they’re on.
