Over the years i collected millions of locations using a series of satnav receivers. My map shows waypoints, trackpoints and most visited countries. Tracks are color coded by average speed, blue is slow and red is fast
Cycling, skating, etc. All tracks recorded with a sports watch or bike navigator. Blue is slow, red is fast.
Map of some texts i wrote on my wiki. Links are not functional (yet). Gotta fix that one of these days.
Beidou is the chinese satnav system. The map shows tha maximum number of satellites observed in a hexagon in colour. The number in the hexagon is the mean number of Beidou satellites. The map is based on one million combined GPS-Beidou locations recorded over a year.
