He is a GDAL and MapServer Project Steering Committee member, the maintainer of the Proj.4 coordinate system library, a former OSGeo board member, a contributing author to the IETF GeoJSON standard, and an active participant in the ASPRS LAS committee. His company, Hobu, Inc., develops open source solutions for clients such as the U.S. Army Corps of Engineers to manage and operate point cloud data warehousing systems. He still doesn't know how to merge CVS branches, and his pull requests usually contain gobs of cruft.</span><span style="" class=""></span></div><p class="MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span style="font-family: Arial, sans-serif;" class=""> </span></p><p class="MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;"><span style="" class=""> </span></p><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="font-family: Helvetica, sans-serif;" class="">A history, status report, and outlook of Proj.4 </span><span style="" class=""></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="font-family: HelveticaNeue, serif;" class="">--------------------------------------------------------------------------------</span><span style="" class=""></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="font-family: HelveticaNeue, serif;" class="">The Proj.4 library and its many language ports provides the coordinate system math implementation that underlies most of the FOSS4G software ecosystem.
