[OSM-newbies] Working on Manhattan

[topo at joelertola.com]

Ok I added connections to the street for the main park. But I left the  
foot paths for little triangular park unconnected to the street. It is  
not clear to me where these paths should end. They exit the park at  
the sidewalk but you would not want to cross the street at those points.

On a similar subject I was working on the West Side Highway last  
night. http://www.openstreetmap.org/? 
lat=40.7482&lon=-74.00846&zoom=16. If you look at the area with the  
Edit tab I think you can see what I have done. There are places where  
pedestrians can cross the highway at traffic lights. Should I draw a  
pedestrian crossing line across the street at those places? If so the  
ends of those lines will not touch anything as the map does not show   
sidewalks. Also should I put in traffic lights?
