Originally introduced in 2015 as “The Pines in the 1940’s” for Google Maps , this collection of 29 historical topographic maps is now available in a universal format for Windows, MacOS, Linux, Android, iOS and handheld GPS units. They were drawn at the same 1:62,500 scale as the older 19th century topos but had a more modern style that included forest shading, buildings and other features. By the early 1950’s the new 1:24,000 scale (24k) topos began replacing these older, less accurate maps.
The free open source Mobile Atlas Creator program is used to view the map on your computer and export it to your favorite mobile apps, desktop software and dedicated gps units. A detailed tutorial will get you up and running quickly.
While the style of these older 1:62,500 scale maps is similar to the newer 24k topos, they were substantially less detailed. The examples below
both show the exact same part of the map.
