I will be camping in Nickerson State Park in June. I have made GPS traces on past trips, but have never had time to use them to improve the map. I am doing it now.
The Bing aerial imagery is of lower-than-typical resolution and many of the roads run under trees, so it is sometimes hard to tell where they go. The traces help to piece them together.
I have tried to draw the bike trail and the walking trails around the lakes, but I have had to guess in parts. I hope to make some new traces next month and improve the map furthur when I get back.
