Maps Treasure Hunt displays old maps as overlays on top of current street or satellite maps. This is possible because we georeference old maps, and offer them as in-app purchases. Some of these maps are public domain Sanborn fire insurance maps. Others are public domain old atlases maps. By using your device GPS capabilities, you can now see where you are on the old map, on the current map, or a combination of both. This allows you to find where structures were located hundreds of years ago, and makes finding artifacts easier.

The app, an old map, and your device GPS can get you where you might find those buried treasures. The maps are offered in three forms: mobile, browser, and Google Earth(TM) KML super overlay. We recommend purchasing the browser or Google Earth version to study the town of interest. Then, before you are ready to enter the areas of interest, purchase the mobile version. Some maps are extremely detailed and download times can take several hours. So we recommend you purchase and download the mobile version ahead of time.
