Launch Google MapsLaunch Maps in LUNA Browser The over 120 historical maps in the Google Maps have been selected by David Rumsey from his collection of more than 150,000 historical maps; in addition, there are a few maps from collections with which he collaborates. These maps can also be seen in the Gallery layer of Google Earth, Rumsey Historical Maps layer, and in the Google Earth viewers on this website. All the maps contain rich information about the past and represent a sampling of time periods (1680 to 1930), scales, and cartographic art, resulting in visual history stories that only old maps can tell. Each map has been georeferenced, thus creating unique digital map images that allow the old maps to appear in their correct places on the modern globe. The original historical maps are first made into digital images by scanning them with high resolution digital cameras. Processing and hosting of the Rumsey Historical Maps in Google Maps is provided by Geogarage.
