Description

A seamless collection of twenty nine Southern New Jersey USGS 1:62,500 historical topographic maps from the middle of the 20th century. These maps were the precursors to the 1:24,000 scale (24k) USGS topo maps and an upgrade to the 19th century topos because they contained forest shading and other features that give them a more modern look. But the 1:62,500 scale does not allow for as much detail as the newer 24k topographic maps which began replacing them in the early 1950's.

To create the map, individual PDF files were downloaded from the USGS Historical Topographic Map Collection and converted to GeoTIFF format. Color correction was applied in Photoshop, the collars were removed, they were joined into a seamless geoTIFF file and finally converted to a tiled format for online use.
