I have worked in the geospatial industry for 25 years. I am currently a co-founder and VP of geospatial technology at Ubisense, where I am leading the development of a product called Ubisense myWorld, which is focused on simple to use mapping for utilities and telcos, and makes use of several open source geospatial products including PostGIS, MapFish and OpenLayers. Previously I have been CTO of two of the top three (closed source) geospatial software companies (and two of the world's top 200 software companies) Intergraph, and Smallworld (now part of GE). I am chair of the FOSS4G 2011 conference in Denver.
I have contributed to several industry open data standards including the Open Geospatial Consortium in its formative years, and IEC TC57 Working Group 14 (for exchange of electric utility data). I am an active participant in and advocate for OpenStreetMap. I was a member of the Board of GITA (the Geospatial Information and Technology Association) for 5 years, from 2004 through 2008, and am again in 2011. I have been a member of the GeoWorld magazine Editorial Advisory Board since 1996, have published many articles and spoken at many conferences around the world, and write a blog called geothought.
I'm an active advocate for open source geospatial software. I speak regularly about open source at conferences. I have helped organize local events for FRUGOS, the Front Range Users of Geospatial Open Source, in Colorado. I was an organizer of the WhereCamp5280 event in Denver in 2009 and 2010.
