"The online Prince George's Atlas is a virtual treasure trove of historic aerial photos, maps and other cartographic information about the region," writes Daniel Walter Rowlands.

Rowlands offers a tour, so to speak, of the atlas, which is maintained by the Maryland-National Capital Park and Planning Commission (M-NCPPC). The tour includes visits to the two oldest maps of the County, the 1861 Martenet Map and the 1878 Hopkins Atlas, but also advice on how to check out aerial imagery dating back to the 1930s and the layers of infrastructure and property boundaries that crisscross the region now.
