The New York Public Library is home to one of the world’s premier map collections, including 433,000 sheet maps and 20,000 books and atlases published between the 15th and 21st centuries. Its Map Warper (available at maps.nypl.org) is a free online crowdsourcing tool that enables both librarians and the general public to align digital images of historical maps with today’s map through a process called georectification, or “warping” maps. Workshop participants will use the Map Warper to explore the library’s digital map collection and generate georectified map images. This work creates new public resources for research and supports ongoing digital mapping initiatives at the Library.
