Abstract: A method, a data processing apparatus, and a positioning apparatus for generating a fingerprint map for an unexplored area are proposed. The method includes receiving, by a data processing apparatus, locations of reference points and locations of a plurality of access points (APs) for a service area, extracting, by the data processing apparatus, feature vectors for each AP on a basis of the locations of the reference points and the locations of the APs, generating, by the data processing apparatus, a fingerprint map for each of the APs by inputting, as conditions, the feature vectors extracted for each corresponding AP into a previously trained generative model for each of the APs and inputting random noise, and generating, by the data processing apparatus, a final fingerprint map for the service area by combining the fingerprint maps generated for the APs.
