Description

This map is the newest in the Boyd's Map of the Pines series which dates back to 2008 and was last updated in 2020. Although it was created from contemporary data, an attempt was made to adhere to the style of traditional USGS 24k paper topographic maps.

Resolution is 4 feet (1.2 meters) per pixel, over twice the resolution of traditional USGS 24k topo maps. Coverage area includes Southern New Jersey with portions of Southeastern Pennsylvania, Delaware and Maryland. But the focus is on the New Jersey Pine Barrens and considerable attention was paid to detail in this region. The Pennsylvania, Delaware and Maryland sections haven't received this level of attention and are virtually unchanged from older versions of the map.

For purposes of identification, unpaved roads from the USGS topo maps are shown in black while roads from other sources (such as nineteenth century topo maps, aerial and LIDAR imagery) are shown in a purple color - see the examples below. Although the unpaved roads on this map have been compared to the USGS topo, absolutely no representations are made regarding accuracy. Some roads may be missing or inaccurately represented. Unpaved roads in the Pennsylvania, Delaware and Maryland maps are based on OpenStreetMap data and not the USGS.
