Abstract

A system for creating a representation of a location based on information sensed at the location. For example, apparatuses may comprise various sensors that sense apparatus-related information (e.g., motion, direction, etc.) while also visual, signal, field, etc. information pertaining to a location. Apparatuses may store sensed information about the apparatus while at a particular location, and about the particular location itself, in a mapping database, which may then associate the various types of sensed information with information already stored in the database in order to create a representation of the location.
