September 16, 2010 I've created a new Geocoder.us blog, please help me put the common questions in the blog. Also, I (Rich) have been out of town, and backlogged with fires to fight. I am working to catch up to my backlog. If you have an important issue please email me again, thank you for your patience and support!

April 8, 2010 Geocoder.us is run primarily as a public service by Rich Gibson and Schuyler Erle.

Schuyler Erle, creator of Geocoder.us, spent time in Haiti doing mapping work in support of the relief efforts. Schuyler, John Crowley, and Jeffrey Johnson spoke about Crisis Mapping at the Where 2.0 conference on April 2nd, 2010. Watch their talk here.

The key quote to me (Rich) is 'Open Street Map saved lives in Haiti.'

Rich Gibson has been working on the GigaPan Project, and has technical notes on GigaPanning here.
