Topomancy LLC is a technology cooperative founded in February 2012 by Schuyler D. Erle, Shekhar Krishnan and Timothy F. Waters. From 2008 to 2012, we were known as Entropy Free LLC.


We work in geo-spatial web development, geographic information systems (GIS), digital archives and libraries, urban and environmental mapping, humanitarian relief and citizen-centric computing.


We are currently supported by the Library of Congress, and by the New York Public Library (NYPL) Labs and the NYPL Lionel Pincus & Princess Firyal Maps Division through a grant from the National Endowment for Humanities (NEH).
