Boyd’s Map of the Pines 2020


This map is the newest in the “Map of the Pines” series which dates back to 2008 and is a major update to Boyd’s Map of the Pines HD from 2017. The list of new features includes:

Almost 1.8 million buildings from Microsoft’s US Building Footprint dataset, providing complete coverage throughout the region
More than 1.4 million New Jersey tax parcel boundaries from 2020 data
Over 4,400 historical building locations, hand-traced from vintage aerial imagery and topographic maps
Almost 2,500 miles of HD unpaved roads, hand-traced from aerial imagery and USGS 24k topo maps
Unique new landcover includes graphic representations of forests, crops, marshes, bogs, beaches, gravel pits and more
New contour lines with 5-foot intervals, created from 2020 USGS 3DEP 1/3 arc-second (10-meter) DEM
More historical towns and points of interest from vintage topographic maps
Extended coverage North to Interstate 195, adding about 370 square miles to the map
New map-making workflow with less image compression provides enhanced clarity and less distortion

New features from 2020 NJDEP data:

Greatly expanded openspace
Over 300 miles of hiking trails
Parking areas, boat launches, picnic areas, campsites and restrooms
NJ Natural Heritage Priority Sites
Solar power facilities
Earthquake epicenters
Landfill locations
