New York Public Library Posts Maps

April 5, 2014

The New York Public Library has a massive collection of beautiful maps, but instead of keeping them locked in an archive Motherboard reports, “The New York Public Library Releases 20,000 Beautiful High Resolution Maps.”

All of the 20,000 maps are available via open access. What is even more amazing is that the NYPL decided to release the maps under the Creative Commons CCO 1.0 Universal Public Domain Dedication. If you are unfamiliar with a Creative Commons license, it means that users are free to download content and do whatever they want with it.

“Combined with its existing historical GIS program, the NYPL wants its users to engage with the maps, and allows them to warp (fitting together based on corresponding anchor points) and overlay the historic maps with modern geoweb services like Google and Open Street Map. Users can export WMS, KML files, and high-quality TIFFs. The historic map appears side by side with the modern maps, and users are invited to mark corresponding points on each, so you can overlay the historic map over the current day’s.”

Google Maps using old maps to explore the world of the past. It is yet another amazing use of modern technology and makes one wonder what people of yesterday would have thought about exploring their world via a small box.
