I tried generating a map with log($size)/log($max): http://u.nix.is/~avar/osm-heatmap-log.png I tried playing around with it a bit more, e.g. by using log10. But mostly I get maps that are too hot. Or was log($size)/log($max) not what you meant? $size / ($median * 32) works pretty well though: http://u.nix.is/~avar/osm-heatmap-black-2.png _______________________________________________ Tilesathome mailing list [email protected] http://lists.openstreetmap.org/listinfo/tilesathome
