Additionally, satellite signals can be jammed or masked. In today’s era of GPS and other geospatial technologies, are compasses still needed? Yes! For a stationary device, GPS does not provide a pointing direction. The video below shows how using the CrowdMag smartphone app during your everyday activity will help us improve navigation for everyone. Become a citizen scientist and join our research on Earth's geomagnetic field. Success of the CrowdMag project depends on the participation of citizen scientists like you.

To build, grow, and foster a worldwide community of citizen scientists and enthusiasts collecting magnetic field data and sharing it to further our understanding of the Earth’s magnetic field.ĭevelop magnetic models and maps using the data shared by CrowdMag users in combination with data collected by ships, aircrafts and satellites, with an aim to fill in the gaps of professional mapping of Earth’s magnetic field.At our server, we check the quality of the magnetic data and share data with the public as aggregate maps and charts. With CrowdMag mobile apps, phones all around the world can send magnetometer data to our research group. In NOAA’s CrowdMag project, we explore whether the digital magnetometers built in modern mobile smartphones can be used as scientific instruments.
If you have to reset your phone, or switch to a new phone, you can now import your backup and continue using CrowdMag without losing your status for data contributed, areas covered, or magtivities completed.ĬrowdMag’s magnetic calculator provides magnetic variation (declination), the magnetic field’s dip angle, the total magnetic field and other magnetic field components (as well as their associated uncertainties) based on the latest World Magnetic Model (WMM2020). Getting a new phone? Don’t worry! You can now export a backup of your CrowdMag and save it on your computer. We especially encourage you to share your magtivities with our research group at NOAA and to have multiple magtivities along the same path so that we can stack the data to reduce the noise and produce a more accurate magnetic field map.
Save, list, export or delete magtivities to create a complete magnetic field map of your area. CrowdMag is going active! When you go out for a walk, run, or other outdoor activities, use CrowdMag to measure the magnetic data along your path and save the data as a “magtivity”.
