The Hill Mapper San Francisco makes peachy purpose of the Google Maps API Elevation Service to demo the management of the slopes on San Francisco's streets.
The uphill streets are colored ruby-red together with the blueish streets larn downhill. The darker the color of the street, the steeper the hill. If you lot deed your place on the map the colors of the streets dynamically update to reverberate the novel directions of the slopes, relevant to your novel position.
I'd beloved to come across cycling directions added to this map, amongst a road dragging option, then that you lot could conception a cycle road that avoided steep uphill climbs.
