I'd really like to find a way of associating points with similar characteristics within x km of each other first. I'm guessing I'd need to run some script which uniquely identifies the existence of clusters and updates an additional field in the postgis table for members of each cluster. For example, creating a Delaunay triangulation and filtering out all the points where the the sides of the triangles are longer than x km but I've no idea how to do that | |
