Everywhere I’ve Been: Data Portraits Powered by 3.5 years of data and 2.5 million GPS Points is the title of a post by Aaron Parecki Geoloqi co-founder. It's written in part to keep up the buzz from SXSW, but it's pretty interesting and includes both the why and the how of the data collection. The maps remind me of an exercise I did in college where we mapped our routes and where we were for two full weeks on 4' x 6' paper maps. The results are pretty much the same: we all follow some regular patterns that define what I like to call an "orbit." (Credit for that term goes to reader Larry.)
