• Dutch Farmhouses of Brooklyn — by Bicycle!
    Although NYPL's NYC Space/Time Directory project ended last December, NYPL's Map Division will continue to organize meetups! The first event of this meetup series in 2018 will take participants on a guided bicycle tour along historical Dutch farmhouses in Brooklyn. The tour: Bicycle tour participants will gather in Grand Army Plaza near the Brooklyn Public Library. The tour begins with a short presentation about the Dutch-American architectural history of early Brooklyn by Walter R. Wheeler (bio below). Participants then depart for a 3-hour tour through the former towns of Flatlands, Gravesend and Flatbush, visiting five Dutch farmhouses on the way, before returning to Prospect Park. Total distance: about 15 miles; about 90 minutes of riding with frequent stops/breaks. At some sites, the group will briefly tour the surviving farmhouses. At others, views of the exteriors will be available. The last “site” will be the former location of a now-demolished farmhouse, demonstrating what used to stand in the now dense apartment-block landscape of central Flatbush. After the tour, everyone is invited to join us for drinks in a Prospect Lefferts Garden bar (location TBD). For details about the route and sites, see https://bertspaan.nl/dutch-farmhouses-of-brooklyn/. Biography Walter R. Wheeler: Walter R. Wheeler has more than 30 years of experience as an architectural historian and author. He begun his career at the Office of the State Architect in Albany and later worked in private practice with Wagoner & Reynolds Architects. Since 1999, Mr. Wheeler has served as Senior Architectural Historian at Hartgen Archaeological Associates, a cultural resource management firm located in Rensselaer. Mr. Wheeler has authored numerous scholarly articles and two monographs on New York State architecture. He is currently at work on a book for SUNY Press, which will document the vernacular architecture of the upper Hudson Valley. He serves as Vice President of the Dutch Barn Preservation Society, President of the Society for the Preservation of Hudson Valley Vernacular Architecture, and board member of the Albany County Historical Association. Sites: - Wyckoff House Museum / Pieter Claesen Wyckoff House (c. 1652), with interior tour - Hendrick Lott House (c. 1720), with grounds tour - Elias Hubbard Ryder House (c. 1834) - Wyckoff-Bennett Homestead (c. 1766) - Site of former Vanderveer-Cortelyou House (c. 1787) This program is supported as part of the Dutch Culture USA program by the Consulate General of the Netherlands in New York Producers: Jeremy Lechtzin (StreetDeets founder) and Bert Spaan (former engineer of NYPL's NYC Space/Time Directory).

  • Extracting a Million-Record Dataset from Historical NYC City Directories
    Segarmakers, Wheelwrights, Merchants: Extracting a Million-Record Dataset from Historical NYC City Directories Almost a year ago, during the first meetup in this series (https://www.meetup.com/historical-data-and-maps-at-nypl/events/235450812/), we showed how the New York Public Library is digitizing its volumes of city directories, and how, as part of the NYC Space/Time Directory project, we have started to extract data from these books and turn them into historical datasets. City directories present a tantalizing data source for the demographic, occupational, and spatial history of urban environments. New York City’s listings are no exception, with more than 120 years of directories and over a million entries documenting the city’s inhabitants available for public use. While these directories have been digitized and made publicly available by the NYPL and other institutions, extracting the directory entries for data analysis poses additional challenges involving computer-assisted automated field detection and language parsing. Come hear about updates on this ongoing effort, completed in collaboration with members of New York University’s Data Services team. This event will be more technical than the one last year, and the focus will be on how we are using optical character recognition, statistical modeling and historical addresses to extract, geocode, and visualize the people and businesses listed in the city directories. Project members: • Bert Spaan, NYC Space/Time Directory, NYPL • Stephen Balogh, NYU Spatial Data Repository • Nicholas Wolf, NewYorkScapes Each of us will talk about their role in the project. Afterwards, there will be time for questions and discussion.

  • Historical Transit Maps at The New York Transit Museum
    For one of the last meetups part of NYPL’s NYC Space/Time Directory (http://spacetime.nypl.org) project, we will visit the New York Transit Museum (http://www.nytransitmuseum.org/) for a evening about historical transit maps. Join us to hear about the streetcars, elevated trains, ferries and railroads in use before the construction of the underground subway system, key moments in subway map-making, and maps of New York City’s unbuilt public transit plans. Before and after the talks, attendees will have the opportunity to visit the Museum’s exhibitions. The newly-opened exhibition From Fulton Ferry: Building Downtown Brooklyn (http://www.nytransitmuseum.org/exhibits-collections/exhibits/) tells the story of the role of transportation in the development of Brooklyn. Schedule: • 6:00PM: Doors • 6:30PM: Introduction by Bert Spaan, organizer of this meetup series. • 6:40PM: Speakers: Kathleen Hulser: Kathleen Hulser is curator at the New York Transit Museum. She will talk about how maps represent ideas of the city, as well as practical guides to navigation. The tension between the ambitions of planners and the realities on the ground will provide a foundation for Andrew Lynch’s comments on never-built New York transportation. A selection of maps from the NY Transit Museum archives will complement the digitized images shown in the talks. Andrew Lynch: Andrew Lynch is a CUNY Hunter Alumni, a Brooklyn based cartographer and transit activist. Lynch is the creator of the blog vanshnookenraggen (http://www.vanshnookenraggen.com/) where he has written extensively about the history of the subways in Boston and New York with a focus on the many unrealized expansion projects throughout the years. Through this research Lynch has also published meticulously designed expansion projects of his own through his futureMBTA and futureNYCSubway projects. Through maps Lynch will discuss the high hopes planners have had throughout the past century only to see them dashed time and time again and what we can learn from these experiences as we try to expand our transit systems for a new century. The meetup will be free of charge! Important: this event will take place at the New York Transit Museum (http://www.nytransitmuseum.org/about/contact/) on Boerum Place & Schermerhorn Street in Downtown Brooklyn. For GPS directions, use the address “99 Schermerhorn Street, Brooklyn”.

  • NYC Maps, Buildings, and Addresses: Using and combining historic data
    The rich history of NYC can be found in the stories of its neighborhoods; historic maps and building records hold evidence of these stories. Join us to hear more about the city's historic maps and data sets, how NYPL is working to make them more accessible, and how these rich resources can be used to learn about the city's past. In this event, we will focus two neighborhoods in New York City: Brooklyn Heights and the Lower East Side. We will talk about using and combining data from the NYC Space/Time Directory, historical maps, building footprints and other datasets to make new digital maps of NYC’s history. For more information about these datasets, see http://spacetime.nypl.org/#data . Schedule: 6:30PM: Doors 7:00PM: Speakers - Kate Cordes - Jeremy Lechtzin - Bert Spaan Speakers: Kate Cordes: NYPL Assistant Director, Maps, Local History and Genealogy Kate Cordes will tell us more about the Library's rich collection of materials on the Lower East Side. Jeremy Lechtzin is an architectural historian and technology lawyer. He focuses on old Brooklyn, currently writing a data-driven analysis of every house built in Brooklyn Heights and mapping the lost streetscape of the Village of Brooklyn as it existed in 1816.
