I'm Pat Tressel, from Seattle, Washington, USA. I'm a software engineer -- started in Ye Olde Days of FORTRAN and punched cards. Been there, done whatever -- OS internals, drivers, embedded systems, robotics, machine learning & data analysis, web development. I help out on assorted projects, e.g. an autonomous tricycle. ;-)
Got into GIS data after the Haiti earthquake, and started mapping sometime later. Have been mapping primarily for HOT. Currently helping organize the Hands-On Day (a.k.a. Hack Day) for SOTM-US 2016.
