Hitchwiki is a collaboratively sourced site for information about hitchhiking and other cheap forms of transportation. Hitchwiki includes a map with geolocated notes from hitchhikers, describing their experience hitchhiking in a given spot.
The Hitchwiki Maps API provides developer access to map data. Applications can programmatically access information on particular locations or retrieve a list of places that meet a specified criteria. Default information includes latitude, longitude, elevation, rating, and other geographic details.
