I want to create a large database of GPS coordinates that can be queried by saying "Return all coordinates that are within 'n' metres of [this coordinate]".
I need it to be as efficient as possible so looping through all the coordinates in the datastore and calculating whether a coordinate is within 'n' metres wouldn't be a desired solution. Is there a "spatial data" feature within the appengine datastore which could help me with this or am I going to have trouble implementing such a feature?
