Hi Craig, Some of use cases are as follows:
1- Given a set of nodes with polygon geometry, find in which polygon a given point coordinates is located in 2- Given a set of nodes with geometry type point, find all nodes which thier distance to a given point coordinate is less than a given radius r 3- Given a set of nodes with geometry type point, which are located in a bounding box, 4- Given a set of nodes with geometry type point, find k nodes closest to a given point geometry (knn) Thanks, Best, Alireza On Sunday, May 24, 2015 at 2:20:23 PM UTC+2, Craig Taverner wrote: > > Hi Alireza, > > Yes and no.
