PostGIS is developed by Refractions Research Inc, as a spatial database technology research project. Refractions is a GIS and database consulting company in Victoria, British Columbia, Canada, specializing in data integration and custom software development. We plan on supporting and developing PostGIS to support a range of important GIS functionality, including full OpenGIS support, advanced topological constructs (coverages, surfaces, networks), desktop user interface tools for viewing and editing GIS data, and web-based access tools.
Coordinates bug fixing and maintenance effort, alignment of PostGIS with PostgreSQL releases, windows build, integration of new GEOS functionality, and new function enhancements.
Release Manager, coordinates general direction of the project, often gets his hands dirty doing real coding.
