Hi my name is Mark. I have a keen interest in open source projects, GPS, photogrammetry, computational linguistics and semantic web theory.

My work on the OpenStreetMap is mostly confined to the buildings in and around Strabane.

Founder of the OldStrabaneBlog http://oldstrabane.blogspot.co.uk

I also contribute data to the Sketchup 3dWarehouse, and several online historical projects including Sepiatown, History Pin and WhatWasThere.
