I am a project steering committee member or BDFL for the following projects.
- PostGIS was started under my direction at Refractions Research in 2001, but I didn’t start actively working on it as a developer until 2008. Since then, I’ve re-written the on-disk format, the statistics gathering system, the WKT and WKB parsers, and many other core components.
- This PostgreSQL extension allows point cloud data (often collected with LIDAR, but not restricted to it) to be stored and filtered inside the database. The core concept is a compressed “patch” of points, which provide 3x compression using simple techniques, and SQL access to the points within via accessor functions.
- This PostgreSQL foreign data wrapper extension allows OGR data sources (and OGR supports access to dozens of formats) to be accessed directly within the database as a table. This makes integration of data from Oracle, SQL Server, FGDB files, WFS servers, and many more possible directly within the database.
- This PostgreSQL extension allows direct access to HTTP web services using a simple SQL functional interface. Just call
http_post() in your SQL query, and data can be pushed and pulled from web services.
I am also a committer on a number of other geospatial open source projects.
- Over the years, I have worked on the PostGIS drivers and on the GDAL format driver for MapServer, as well as specialty projects like supporting XMP metadata embedding.
- I arranged the financial backing that brought the GEOS port of JTS into existence in 2003. I have provided minor patches and general guidance to the project as a community member since then.
