Abstract
A method and system for creating and/or using a universal location referencing object (ULRO) with electronic files including electronic maps. ULROs establish traversable links between a file-of-reference and third-party-files. In accordance with an embodiment, the ULRO comprises a universal location referencing code uniquely corresponding to the location, together with several optional components, including: a set of name information; a super-set of coordinates; a file-of-reference pointer field comprising a file-of-reference pointer; a third-party-file pointer field comprising one or more third-party-file pointers; a file-of-reference back-pointer field comprising a file-of-reference back-pointer; a third-party-file back-pointer field comprising one or more third-party-file back-pointers; and a metadata field. ULROs allow recognition of equivalence of features in different maps, and facilitate dynamic combination or linking of multiple maps into one virtual map, with traversable connectivity for a wide variety of map formats.
