Abstract: Systems and methods are disclosed for creating a magnetic map by obtaining magnetic field measurements from a plurality of platforms. A first set of poses for each platform is determined and information from the magnetic map is obtained for any existing magnetic field values for the first set. Magnetic constraints on poses of the platform are determined and used for determining a second set of poses for each platform. The magnetic field values of the magnetic map are then updated based at least in part on the second set of poses for each platform.
