Hi guys, I created a visualization showing the node density of OSM data in the Philippines taken from the 2012-01-02 Geofabrik extract. Each pixel represents a 0.1°×0.1° degree square or approximately 1 square kilometer. Brighter pixels represent areas with higher node counts.
View it here: http://wiki.openstreetmap.org/w/images/8/81/Philippines_node_density_2012-01-02.png The edges of available satellite imagery at that time is quite visible in some areas like Pangasinan, Cebu, Bukidnon, and Davao del Sur. As expected, brighter areas are places where there is a large amount of editing and with a large population. By the way, can you guess which place has the densest concentration of nodes (the only purely white pixel in the image)? It's in Naga City and this is due to the Naga City import. The second densest location is in Marikina, and this is thanks to maning's efforts in mapping all of the buildings in his adopted city. :-) Eugene _______________________________________________ talk-ph mailing list talk-ph@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-ph
