POINT OF INTEREST DATABASE MAINTENANCE SYSTEM
First Claim
1. A method of processing data for maintenance of a database of points of interest (POI), each point of interest represented in the database having at least one attribute and a time-varying confidence value indicative of the accuracy of the at least one attribute associated therewith, the method comprising:
- transmitting a request to one or more remote devices to provide confirmation of an attribute of a point of interest when the confidence value associated with the point of interest is below a predetermined threshold;
receiving a report relating to the attribute in response to the transmitted request from at least one of the remote devices; and
adjusting the confidence value associated with the point of interest in accordance with the received report.

Abstract
A method of processing data at a server (302) for maintenance of a database (516) of points of interest, such as speed limit enforcement devices. Each of the devices represented in the database has at least one attribute and a confidence value indicative of the accuracy of the at least one attribute associated therewith. The confidence value is time dependent and varies according to a pre-defined decay function. A report (500) relating to an attribute of a speed limit enforcement device is received at the server (302) from a mobile device (200). The confidence value associated with the speed limit enforcement device is adjusted in accordance with the received report, and information relating to the speed limit enforcement device (520, 522) is selectively transmitted to the or another mobile device (200) based on the confidence value.

13. A non-transitory computer readable medium comprising computer program code adapted, when said computer program code is run on a computer, to cause the computer to perform a method of processing data for maintenance of a database of points of interest (POI), each point of interest represented in the database having at least one attribute and a time-varying confidence value indicative of the accuracy of the at least one attribute associated therewith, the method comprising:
-
transmitting a request to one or more remote devices to provide confirmation of an attribute of a point of interest when the confidence value associated with the point of interest is below a predetermined threshold; receiving a report relating to the attribute in response to the transmitted request from at least one of the remote devices; and adjusting the confidence value associated with the point of interest in accordance with the received report.
