Just one suggestion related to features used for clustering, can you consider using LINE features as well.  My particular need could use points as described and probably still work nicely.  My specific need is for applying heat mapping to trail (GPS, Average Daily Traffic) lines, these lines are generated from points sequences though, so this would still be doable as RFC describes.

There are occasional instances where long segments are introduced into the GPS data collections where a GPS lock goes missing for a while, these long lines are the things I would like incuded in a heatmap output.  Maybe there is a way to interpolate some points along a line that would still work with the scribed system as another mode of processing.

Good stuff all around either way.

History trivia, ask Steve L. sometime, about some heat-map work we did more than ten years ago now for an online mapping interface.

please have a look at RFC-108 [1]. The associated code and the RFC are still beta, so there's still plenty of room for modification or remarks.
