Hi,
I have a use case where I have to find a set of points near another set of
points. For example, given
Set A = { a1, a2, ... an} and Set B = {b1, b2, b3.. bn}
Set A and B are from two different tables. Can I frame a query (SQL) by
using postgis functions to find a set of points of type B that are
near a given set of points of type A?
Any pointers/hints about postgis functions are greatly appreciated.
Thanks
Babu
