heatmap TAH 3
This is my attempt at remixing the Tiles@Home Heatmap by Ævar Arnfjörð Bjarmason (on flickr)
This is a matplotlib/python implementation (the original is in Perl)
The heatmap uses the file size of each tile, which should give a good measure of how much real data there is in a tile. Red areas have lots of data, green areas less, and blue the least.
Data sources: www.openstreetmap.org/, Tiles@Home
Source code on OSM repository : original, mine.
I've used log10 scaling for the colours, so the rural areas get a bit more prominence.
A bit of photoshop work in this case to mask out the ocean areas.
