CrowdMag

This app measures magnetic field and display the data as graph or map in units of nanotesla (nT; one nanotesla equals 10^−9 tesla). Displays Z (downward component), H (horizontal intensity) and F (total intensity) of the local magnetic field vector. Data processing reduces the noise in the data to about 1% of the actual magnetic field. We rotate the magnetic data from the phone’s orientation to the real-world coordinates. Use it for recording magnetic data at a location or over an area. Export your data as a CSV file. Optionally, enable background reporting to help NOAA scientists understand more about the Earth’s magnetic field!

The new addition, Compass tab features a compass dial and level bubble, true North, local magnetic North, magnetic declination from World Magnetic Model, compass accuracy and current solar magnetic disturbance!

Use CrowdMag app as an offline magnetic calculator. Quickly get magnetic variation at remote sites or ships. Calculator gives magnetic variation (declination), dip angle, total field and other magnetic field components for date and location based on the latest World Magnetic Model (WMM2015). The model is developed primarily using data from ESA’s SWARM satellites and it accurately predicts the main magnetic field anywhere on the globe. It also provides the uncertainty and the time change of the modeled magnetic field.

CrowdMag Features:

- Customize recording frequency and location accuracy
- Interactive Google Map showing your magnetic data
- Graph your data as time series
- Check the quality of the data by comparing with WMM
- Export your data as a CSV file
- Enable/disable background reporting
- Clear stored data on your phone
- Optionally share your data with NOAA
- See crowdsourced magnetic data from other users
Compass Features:
-Compass dial
-Level Bubble
-True North
-Local Magnetic North
-Compass accuracy
-Current solar magnetic disturbance

Magnetic Calculator:

- Uses the most recent model (WMM2015)
- Compute Declination, Dip and Total Field and other components for given date and location (2014-2019)
- Autolocate your latitude/longitude
- Uncertainty
- Compass rose on a map
- Export data via email, Google Drive and other options
