Creating American Borders

30-second animation of the changes in U.S. historical county boundaries, 1629 - 2000. Historical state and territorial boundaries are also displayed from 178...
Seth Dixon's insight:

I love this time-lapse animation of all the county and state-level boundary changes in United States history.  Would you like to see this in greater detail?  Would you want to download the data and create your own visualization of this?  The Atlas of Historical County Boundaries has all of this data as GIS shapefiles, Google Earth KMZ files and PDFs for the whole country as well as for each individual state.  This project sponsored by The Newberry and the National Endowment for the Humanities has tremendous potential for use in the classroom for history and geography teachers alike.

I love animation maps.  Great for getting students interested in learning.

This video does a fantastic job of showing how the United States has expanded and grown since its original 13 colonies. While many today might imagine that our nation was simply always this size in fact over many years of colonization, land purchases and land grabs America has eventually become what it is today.
