When I was a kid, my father brought home from I know not where an enorÂmous colÂlecÂtion of NationÂal GeoÂgraphÂic magÂaÂzines spanÂning the years 1917 to 1985. I found, tucked in almost every issue, one of the magazine’s gorÂgeous maps—of the Moon, St. PetersÂburg, the Himalayas, EastÂern Europe’s ever-shiftÂing boundÂaries. I became a carÂtogÂraÂphy enthuÂsiÂast and geoÂgraphÂiÂcal sponge, porÂing over them for years just for the sheer enjoyÂment of it, a pleaÂsure that remains with me today. Whether you’re like me and simÂply love the imagÂiÂnaÂtive exerÂcise of tracÂing a map’s lines and conÂtours and absorbÂing inforÂmaÂtion, or you love to do that and you get paid for it, you’ll find innuÂmerÂable ways to spend your time on the new Open Access Maps project at the New York PubÂlic Library. The NYPL announces the release with the explaÂnaÂtion below:
The Lionel PinÂcus & Princess Firyal Map DiviÂsion is very proud to announce the release of more than 20,000 carÂtoÂgraphÂic works as high resÂoÂluÂtion downÂloads. We believe these maps have no known US copyÂright restricÂtions.* To the extent that some jurisÂdicÂtions grant NYPL an addiÂtionÂal copyÂright in the digÂiÂtal reproÂducÂtions of these maps, NYPL is disÂtribÂutÂing these images under a CreÂative ComÂmons CC0 1.0 UniÂverÂsal PubÂlic Domain DedÂiÂcaÂtion. The maps can be viewed through the New York PubÂlic Library’s DigÂiÂtal ColÂlecÂtions page, and downÂloaded (!), through the Map WarpÂer.
What does this mean? SimÂply put, “it means you can have the maps, all of them if you want, for free, in high resÂoÂluÂtion.” Maps like that above, of New York’s CenÂtral Park, issued in 1863, ten years before FredÂerÂick Law OlmÂstÂed and Calvert Vaux comÂpletÂed their hisÂtoric re-design.
Can you—as I did with my neatÂly foldÂed, yelÂlowÂing archive—have all the maps in full-colÂor print? Well, no, unless you’re preÂpared to bear the cost in ink and paper and have some speÂcialÂized printÂing equipÂment that can renÂder each map in its origÂiÂnal dimenÂsions. But you can access someÂthing worlds away from what I could have imagined—a digÂiÂtal enhanceÂment techÂnolÂoÂgy called “warpÂing,” also known as “geoÂrecÂtiÂfiÂcaÂtion.”
This, explains the NYPL, “is the process where digÂiÂtal images of maps are stretched, placÂing the maps themÂselves into their geoÂgraphÂic conÂtext, renÂdered either on the webÂsite or with tools such as Google Earth.” For examÂple, below see a “warpÂing” of the 1916 Redraft of the 1660 “CastelÂlo Plan” for then-New AmsÂterÂdam over a curÂrent-day Google Earth image of lowÂer ManÂhatÂtan (and note how much the island has been expandÂed past its 17th cenÂtuÂry shores). The “warpÂing” techÂnolÂoÂgy is open access, meanÂing that “anyÂbody with a comÂputÂer can creÂate an account, log in, and begin warpÂing and tracÂing maps.” User conÂtriÂbuÂtions remain, “a la Wikipedia,” and add “one more piece to this new hisÂtorÂiÂcal geoÂgraphÂic data modÂel.”

The “warpÂer” is a speÂcial feaÂture that helps place hisÂtorÂiÂcal maps in a modÂern visuÂal field, but it in no way ruins the enjoyÂment of those maps as archival pieces or art objects. You can see carÂtogÂraÂphÂer John WolÂcott Adams origÂiÂnal 1916 CastelÂlo Plan redraft below, and visÂit NYPL’s DigÂiÂtal ColÂlecÂtions for a high resÂoÂluÂtion image, fulÂly zoomable and, yes, printÂable. For more on the incredÂiÂble warpÂing techÂnolÂoÂgy NYPL makes availÂable to us, see this extendÂed blog post, “UnbindÂing the Atlas: WorkÂing with DigÂiÂtal Maps.” Over ten thouÂsand of the collection’s maps are of New York and New JerÂsey, datÂing from 1852 to 1922, includÂing propÂerÂty, zonÂing, and topoÂgraphÂic maps. In addiÂtion, over one thouÂsand of the maps depict Mid-Atlantic cities from the 16th to the 19th cenÂturies, and over 700 are topoÂgraphÂic maps of the AusÂtro-HunÂgarÂiÂan Empire between 1877 and 1914. That should be enough to keep any amaÂteur or proÂfesÂsionÂal map-lover busy for a good long while. Start digÂging into the maps here.
