Google Earth

This page links to a number of historic maps, atlases and drawings that are overlayed in Google Earth. Information on how map overlays are created is available at www.railsandtrails.com/mapoverlays/. Most links require the the free Google Earth software be installed on your computer. (Google Maps and the Google Earth plug-in have limited support for the Google Earth KML file format)

Next click on the link below to load the Google Earth KML file for the map image(s) you would like to view. The KML file will load in Google Earth in your Temporary Places area. By checking and unchecking the item you can turn them on or off. There is also a transparency control to view the underlying layers. For more help view this pdf.
