Map Warper

Try the Free Online Map Warper

From 2008 to 2015, Topomancy developed and deployed the New York Public Library (NYPL) Map Warper, NYPL’s web application for showcasing its vast collection of historical maps to the public. The Warper allows citizens and volunteers to geo-reference (“warp”) historical maps, atlases and imagery to real geographic space. Simple “crowd-sourcing” tools also allow for cropping and stitching maps into atlases, and extracting and annotating features from historical imagery for use in other applications. In daily use for almost a decade, development of the Map Warper has been supported by NYPL Labs, the National Endowment for Humanities (NEH) and the Knight Foundation.

Digital Gazetteer

Web Demo Coming Back Online Soon

From 2009 to 2013, Topomancy developed a Digital Gazetteer for the Library of Congress (LoC). The Digital Gazetteer, which powers geographic search across collections, is an API, web framework and custom database for correcting and dis-ambiguating place names (“toponyms”) over chronological time and geographic space. It has been deployed for internal use since 2013 in remediating bibliographic metadata across specialized library collections at the Library of Congress through its Office of Strategic Initiatives (OSI). Digital Gazetteer web framework design was supported in an open-source collaboration on the New York City Chronology of Places with the NYPL Maps Division in 2012-2013, part of the NYPL Space/Time Directory.
