Chris Holmes

VP, Strategic Development, The Open Planning Project (TOPP)

Chris Holmes is Managing Director, Strategic Development of The Open Planning Project (TOPP), a non-profit organization based in New York. TOPP's mission is to build technology to enhance the role of the citizen in democratic society, and leads development on the open source GeoServer Project to help create a free, distributed, and open geographic information infrastructure. TOPP is more of a hybrid organization, similar to the Mozilla Foundation, in that it employs top developers to advance the state of open source software, but with sustainable business models so that it need not rely on continued fund-raising. Holmes has served as lead developer of GeoServer, on the Project Management Committee of GeoTools, and is additionally a founding board member of the new Open Source Geospatial Foundation, where he focusus on GeoTools and the Public Geospatial Data Committee.
