CrowdMag - crowdsourcing Earth’s magnetic data
Did you know the smartphone you carry with you is a traveling magnetic observatory?
You can become a Citizen Scientist and help improve navigation by using the CrowdMag Smartphone App.
This video explains how your everyday activities (walking, running, cycling, etc.) combined with the CrowdMag phone app will collect the Earth’s magnetic data.
At NOAA, we will create maps and computer models of the Earth's magnetic field based on the crowdsourced data collected by Citizen Scientists like you.
