A web tool called Flatten SF lets users find the flattest route between any two points in San Francisco, rather than the shortest or fastest one. The city's famously steep hills make this a genuinely useful feature for cyclists, runners and pedestrians who want to avoid gruelling climbs. It has drawn attention on Hacker News, where commenters are discussing the routing challenge and San Francisco's notorious topography.

Flatten SF is a new browser tool that calculates routes across San Francisco by balancing distance against elevation gain. It combines one-metre-resolution lidar elevation data from the USGS with the Overture street network graph to suggest paths that spare pedestrians the city's famously steep climbs. The project is drawing attention among developers and urbanists as a practical example of open geodata put to everyday use.
