![]() ![]() The result is an exploration of time as well as space, a marriage of historic cartographic masterpieces with innovative contemporary software tools. Often the image has to be curved a bit for this to be accomplished. The GIS program then takes all these points (as many as 200 are made for very large maps) and uses them to recreate the digital image so it will fit into its modern geographical space. Georeferencing is done using a GIS program, which takes points on the old maps (cities, coast lines, rivers, streets) and connects them to the same points on a modern satellite map image or a modern street map or a modern map showing boundaries of countries and states. Then these digital images are transformed in a process called georeferencing, which makes them display in their correct geographical spaces in Google Maps and Earth. Introduction View in Google Earth KML Developers Screenshots MGMaps home. The original historical maps are first made into digital images by scanning them with high resolution digital cameras. Cultural features on the maps can be compared to the modern satellite views using the slider bars to adjust transparency. Some of the maps fit perfectly in their modern spaces, while others (generally earlier period maps) reveal interesting geographical misconceptions of their time and therefore have to be more distorted to fit properly in Google Maps and Earth. 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. A limited group can also be seen in the Google Maps viewer on this website.Īll 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. These maps may be viewed in Google Earth ( requires downloading the app) with our KML links in My Places or in the Gallery layer of Google Earth, Rumsey Historical Maps layer, or directly in the no download Google Earth Browser. If you already have Google Earth Pro (Desktop) installed on your computer, you can just open the downloaded file and you will be able to fly to your objects.The hundreds of historical maps in the Google Earth Rumsey Historical Maps layer 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.
