Hi All,
I've been looking through the GeoTools documentation and search, but
haven't been able to find much on a k-NearestNeighbor algorithm. I'm
really hoping someone can point me in the right direction.
What I need to do is find the k nearest features in a feature collection to
a point. For instance, find the 5 closest features in a shapefile to a
single point. Even better would be a way to find the 5 closest features in
a shapefile to each point in a different shapefile. Is there anything in
GeoTools that can help do this? It would need to work Point-Point,
Point-Line, and Point-Polygon. I'm hoping there is something already and
that it leverages a spatial index to make the query faster since I have to
run this operation a large number of times.
Thanks very much for you help! Hope all is well.
Cheers,
Brett
