A method and system for transmitting and/or receiving at least one location reference, enhanced by at least one focusing factor

Abstract

A method and end user mapping device (200) are disclosed. In at least one embodiment, the method includes receiving information from a remote server (302), at a device, the received information including at least one location reference enhanced by at least one focusing factor, computed at the remote server (302) based upon encoded information corresponding to at least one path of the at least one location reference; and reconstructing the at least one path of the at least one location reference at the device, based upon the received at least one location reference enhanced by the at least one focusing factor.

Description

technical field [0001] Embodiments of the invention generally relate to methods and / or systems for transmitting information, and / or for receiving and processing transmitted information, for example, for use in navigation. Background technique [0002] In recent years, consumers have acquired a variety of devices and systems that enable them to locate a place or destination on a digital map. The term "location" or "destination" is a generic term used throughout the description of embodiments of the present invention. The term "place" or "destination" includes street addresses, buildings located at street addresses (eg, stores and landmarks), and facilities located at several street addresses (eg, shopping malls and business districts). The various devices and systems used by consumers or "users" take the form of: in-vehicle navigation systems, which enable drivers to navigate streets and roads; handheld devices, such as personal digital assistants ("PDAs"), Personal navigat...

Problems solved by technology

[0012] Thus, FRCs are often a possible point of failure in errors when dereferencing locations, noting that cost differences between different maps caused by ambiguous FRC mapping can cause decoding devices such as end user mapping devices 200 to fail at Significant difference when doing path calculations

Furthermore, the introduction of a large amount of heuristic data for map data updates will subject the middle layer FRC to a high rate of change, resulting in a degradation of the location reference matching rate even for data from different versions of map databases from the same vendor
