Why was this tool created? Many people have requested to be able to see historical county lines from the Newberry Library’s Atlas of Historical County Boundaries displayed on top of Google Maps.
While some other tools can show the Newberry Atlas in GIS formats for Google Earth, requiring downloads and installation, this free tool shows the entire Newberry Atlas of Historical County Boundaries overlaid on Google Maps in a web browser. Therefore, you don’t have to download, install or import anything, and you can even use it on your smart phone or tablet.
Coverage Notes– Coverage includes all 50 US states, from as early as 3/4/1629 through 12/31/2000. For present-day county lines use the County Lines on Google Maps tool.
- The Search places box uses a standard Google Maps geocoding engine, therefore you can type PRESENT-day street addresses, road names, points of interest, and GPS coordinates (see * above) to see what county that location is part of
- NEW! Some counties or regions were claimed by more than one jurisdiction in some historic years. When this is the case, an “Overlapping jurisdiction” button will appear at the top of the map enabling you to toggle to the other jurisdiction’s information.
- The map layers from which this information is extracted are very large, so it may take several seconds to finish drawing
- Note that typing an address will zoom in the map very close, whereas typing a city or county by itself will show you a map with a wider view
- Disclaimer: While the number of decimals in the latitude and longitude displayed for the map marker may imply a positional accuracy of within a few feet, note that Google Maps and the source data may not be that accurate. Accordingly, this tool should not be used for legal nor surveying purposes or anything beyond entertainment value.
