Abstract
Provided is a method and apparatus for generating a magnetic field map using a magnetic field value collected in a sample area. The magnetic field map may be used to verify a user location based on a geomagnetic field.
Claims20
A method of generating a magnetic field map, the method comprising:
- collecting a magnetic field value of a sample area comprising at least a portion of a target area;
- verifying a magnetic field characteristic of the sample area based on the magnetic field value of the sample area;
- determining a sampling interval for the target area based on the magnetic field characteristic of the sample area;
- collecting a magnetic field value of the target area at the sampling interval;
- and
- generating a magnetic field map based on the collected magnetic field value of the target area.
