How does a tracking device like a Garmin watch or Strava mob app know what elevation you are, no matter where you are?
In: Technology
Because there’s only one possible elevation you could be when driving or walking, which is ground level. If you’re travelling down a road Garmin can just assume you’re at whatever elevation the ground is. Smartphones use the accelerometer, not GPS, to detect if you’re going up or down stairs.
