As the years passed, the USGS produced new map versions of each area. TopoView shows the many and varied topographic maps of each of these areas through history. This can be particularly useful for historical purposes, such as finding the names of natural and cultural features that have changed over time.
Geologic mapping and topographic mapping at the USGS have a long tradition together see report. These maps are modeled on the familiar 7. This benefits non-specialist map users, as well as applications that need traditional maps. We looked at how researchers can use Google Earth to put their own ancestors on the map and organize the information in their family tree in fascinating new ways.
But even if you aren't using Google Earth, these tools can be used with just a web browser and will still help your research. The latest NY records news, expert genealogy tips, and fascinating stories delivered twice a month to your inbox! Thanks to a process called georeferencing, we can download digitized historical maps and import them into Google Earth.
Here is an example of what the Google Earth map interface looks like without any imported historical maps:. And here is what the same exact area looks like, with a georeferenced, digitized historical map loaded into the program:.
In general, the best way to determine if a digital map can be imported into Google Earth is to see if there is a version of the map available as a file that ends with the extension.
Most operating systems will automatically associate. This means you just need to download the. One challenge of New York research is that many of our ancestors populated the state while local, regional, and national territorial boundaries were evolving.
An ancestor could have lived in one county during one census, and another in the next census without ever having moved their residence—this makes looking for records challenging and creates the possibility that we may be investigating repositories in the wrong county.
The Newberry Atlas of Historical County Boundaries is the perfect tool to meet this challenge head-on. A project of the Newberry Library in Chicago, this website is a fantastic resource for exploring the changing boundaries of counties in all 50 states.

The KMZ file will then be added to the Temporary Places panel, and the state's historical county boundaries will be overlaid on aerial photography of the United States.
This time slider can then be used to view the boundaries at a specific date, or to view an animation of the state's boundary changes over time.
The time slider properties can be adjusted to modify the animation speed, or to view a smaller time span in more detail. With Google Earth, it is possible to compare the historical county boundaries with geographical features such as rivers, lakes, and mountain ridges.
The historical boundaries can also be compared to a large variety of layer information available in Google Earth, such as streets, populated places, and modern administrative boundaries.
