[mkgmap-dev] nearby-POI: What to do with several POI arranged on a circle?From Gerd Petermann GPetermann_muenchen at hotmail.com on Thu May 7 08:42:25 BST 2020
Hi all, while doing further tests I've found this edge case (see attached file) Draw a circle with a diameter of ~56m and tag all nodes amenity=bank. The default style has amenity=bank [0x2f06 resolution 24] With --nearby-poi-rules=0x2f06:30:merge-at-mid-point one might expect a single POI in the middle of the circle, but the result is different: Since there is no POI near the center of the circle the current algo finds 4 groups, all close to the edge of the circle. I think for merge-at-mid-point I need a different algo. I'm looking at https://en.wikipedia.org/wiki/Cluster_analysis now.
