Resource Highlight: NYPL Map Warper

Nifty way to time travel using maps: use the Map Warper from the New York Public Library!

The featured image shows the location of WorldView Software’s offices in Nassau County, New York as they appeared in 1779 (on a map titled “A chorographical map of the province of New-York in North America, divided into counties, manors, patents and townships : exhibiting likewise all the private grants of land made and located in that Province“) and blended with a map from today.  Big difference!

You can play with maps going back to 1544, browse by location and layer, maps that have already been rectified or do it yourself, and you can play with the transparency (ours is at 60%).   What does your area look like?
