On-Line Fitness Map 'accidentally revealed the location of secret military bases' by tracking soldiers' movements


Some of the world’s most secret and sensitive bases in the world are lit up brightly on the running tracker’s map
The Global Heat Map is published by the GPS tracking company Strava, and is made up by sticking together the locations and activities of people who use fitness devices like Fitbits. It lights up places where people have been running over the past two years – including soldiers and other people who are running at secret military bases and sensitive places including Afghanistan.
A closer look at those areas brings into focus the locations and outlines of well-known US military bases, as well as other lesser-known and potentially sensitive sites – possibly because American soldiers and other personnel are using fitness trackers as they move around.
Strava suggests military users ‘opt out’ of heatmap as row deepens 
Fitness-tracking company Strava has defended its publication of heatmaps that accidentally reveal sensitive military positions, arguing that the information was already made public by the users who uploaded it.
