“Everyone who has seen Paul present knows that he is a rockstar, at least when it comes to open source or geospatial software. I was fortunate to work with Paul for five years, during which time he was instrumental in how we approached building, communicating, and selling OpenGeo Suite. Whether evangelizing open source software, speaking and presenting in front of large audiences, architecting solutions, or trying to figure out to most efficient way to build a multidimensional index in PostGIS, I was continually impressed with Paul's understanding and thoughtfulness. He would be a true asset to any growing software organization and comes with my heartfelt recommendation.”

GEOS
GEOS is a C/C++ library for computational geometry with a focus on algorithms used in geographic information systems (GIS) software. It implements the OGC Simple Features geometry model and provides all the spatial functions in that standard as well as many others. GEOS is a core dependency of PostGIS, QGIS, GDAL, Shapely and many others.
