From OpenStreetMap Wiki
- I'm an active mapper, mapping mostly from on the ground surveys combined with imagery, GPS traces or Mapillary.
- I'm a data consumer of OpenStreetmap via my project beyondtracks.com which provides information about walking tracks around Sydney.
- I run an OSM development and consultancy business, Alantgeo, helping organisations benefit from OpenStreetMap.
- I have a personal online presence at tianjara.net.
