1. A method comprising:
accessing, by a network apparatus comprising a processor, a memory storing a geographic database, and a communication interface, information corresponding to one or more traversable map elements (TMEs) within a zone of interest from the geographic database;
determining, by the network apparatus, a respective category of a plurality of categories for each of the one or more TMEs based at least in part on the information corresponding to the TME;
generating, by the network apparatus, a first category encoding data structure based at least in part on map version agnostic identifiers corresponding to TMEs determined to be in a first category of the plurality of categories, wherein the first category encoding data structure is a probabilistic data structure configured to not provide false negatives for TMEs within the zone of interest; and
providing, by the network apparatus, the first category encoding data structure such that a mobile apparatus receives the first category encoding data structure.
