A heatmap of Edinburgh showing access to leisure facilities, using OpenStreetMap data. From an idea by macrofight

Blue areas have good access to leisure areas (such as sports centres, parks, gardens and golf courses) and red areas have poorer access to leisure areas.

Boring science bit :-)

Python/Matplotlib to do parsing, processing and contour plot.

Google Earth was used to project the plot onto OSM Mapnik tile layers.

The 'heat' depends on how far each node is to the closest leisure facility node (a node belonging to a way which is marked as 'leisure', such as the nodes marking the boundary of a golf course). I didn't look for single nodes marked as 'leisure', so it's possible that some smaller facilities might have been missed. However, it should have picked up larger areas such as parks, gardens, golf courses and sports pitches. Distances are simple Euclidian distances on (lat,lon).
