Mapper since: March 01, 2014

As of December 23, 2019, chairperson of the OSM Foundation board of directors. Also on the advisory board of the Caspian Policy Center, a Washington, D.C.-based think tank.

Retired U.S. diplomat previously assigned to Ashgabat, Turkmenistan, for 4-1/2 years. Equipment includes Samsung Galaxy (Android) with Mapillary, MAPS.ME, and 32Gb SD cards for mass collection of ground-level imagery; GoPro Hero 7 Black with 256Gb SD card; Garmin nüvi; and a Wintel desktop PC platform that includes Igor Brejc’s Maperitive program for generating both wall maps and street atlases. I also have a collection of Soviet-era military maps of Turkmenistan for researching municipalities, route numbers, and topographic features. SOTM 2019 voted me the Greatness in Mapping award for that year.
