  "textContent": "In one embodiment, a method includes accessing a magnetic-field map of a region comprising data that represents magnetic-field values that correspond to locations in the region. The method includes accessing a sample magnetic recording comprising data that represents a time or distance series of magnetic measurements made along a path in the region. The method includes at least approximately aligning the sample magnetic recording to the magnetic-field map. Based on the alignment, the method includes generating a first set of parameters for aligning subsequent magnetic recordings to the magnetic-field map across a substantial entirety of the magnetic-field map, and generating one or more second sets of parameters for aligning subsequent magnetic recordings in one or more subdivisions of the magnetic-field map. The method also includes associating the first and second sets of parameters with the magnetic-field map and providing the magnetic-field map with the associated parameters for subsequent navigation.",
