1. A method for generating a wellbore resistivity map, comprising:
receiving a plurality of measurement sets, wherein each measurement set comprises electromagnetic field data associated with a geologic formation;
performing an inversion on each of the plurality of measurement sets to generate a corresponding plurality of formation profiles;
applying at least one filter to each of the formation profiles to generate at least one profile cluster;
selecting a representative cluster from the generated profile clusters; and
generating a wellbore resistivity map to either or both facilitate geosteering and enhance production in association with the geologic formation, wherein the wellbore resistivity map is generated from the representative cluster that is selected from the generated profile clusters.
