Mapping

Some of my past and present mapping projects:

Parks and open space

I enjoy the outdoors and often bring a GPS on hikes and bike rides. These are some of the results.

• Wompatuck State Park. Surveyed every road, trail and other feature in the park. Fixed the road network and added trails, paved bike paths and other features.
• Duxbury Town Forest. Surveyed roads and trails in Duxbury T.F. and surrounding reservations.
• Lynn Woods. Started to add some roads and trails in Lynn Woods. More work needed.
• Blue Hills. Added some roads trails, parking lots and other features. More work needed.
• Bare Cove. Surveyed roads and (some) trails in Bare Cove Park, Hingham, MA.
• Pond Meadow. Adding complete set of bike trails, paths and other features, Pond Meadow Park, Weymouth/Braintree, MA.
• Weymouth, MA. Mapped out bounds, roads/trails/footpaths etc in most local parks
• White Mountains. Added several trails in the White Mountains, NH.

I've also been fixing import errors, such as the Reservoirs issue from the MassGIS OpenSpace import.
