NYC Parks Online
New York City Parks and Recreation Online (NYCPRO) is a Google Maps mashup that lets you discover parks and recreational opportunities in New York City. You can search for parks by neighborhood, as well as limit your search to certain recreational activities.
You can also locate other amenities on the map, such as bike shops, restaurants, hospitals, landmarks, or lodging with the map search, and you can locate multi-use trails in the city.
The map is an entry into the NYC Big Apps Competition. Voting for which began yesterday.
