摘要
There is provided an apparatus for generating an indoor magnetic field map for a building (100), the apparatus caused to acquire information indicating a measured magnetic field vector and information relating to an uncertainty measure of the measured magnetic field vector in at least one known location inside the building (100), wherein the indicated magnetic field vector represents magnitude and direction of the earth's magnetic field (208) affected by the local structures of the building (100), and to generate the indoor magnetic field map for at least part of the building (100) on the basis of at least the acquired information and the floor plan.
