I've been working with map projections and datum transformations for years, including in ArcView GIS, ArcInfo 7 and up, and ArcGIS. I'm a member of the Geodesy subcommittee of the Geomatics committee of the International Organisation of Oil and Gas Producers (IOGP) which maintains the EPSG Geodetic Parameter Registry.

Beyond work, I read a lot of fantasy and science fiction.
