Abstract: A method (and corresponding systems) of navigational guidance for a navigational system, the method includes the following steps. Obtaining one or more route traces of previously travelled routes of a user of the navigational system, each route including a plurality of road segments. Updating an initial set of routing parameters of the navigational system based on attributes of the road segments of the previously travelled routes; generating, based on the updated set of routing parameters, a route between an initial location and a requested destination location. Providing navigational guidance to the user for following the generated route, based on the generated route and a current location of the user.

Abstract: A method is provided in which a device associated with a vehicle generates and transmits probe data samples comprising positional data. The method comprises obtaining detected event sequence data indicative of a sequence of detected events relating to the vehicle, obtaining search pattern data indicative of a search pattern of events and using the search pattern data and at least a portion of the detected event sequence data to determine whether a pattern of detected events matching the obtained search pattern of events is present in the at least a portion of the sequence of detected events. When a pattern of detected events matching the obtained search pattern of events is found in the at least a portion of the sequence of detected events, the device generates a probe data sample comprising data indicative of one or both of the search pattern and the matched pattern of events, and data indicative of a position of the device associated with the matched pattern of events.

Abstract: A method of generating a scenic rating for segments of an electronic map involves obtaining probe data relating to the movement of a plurality of devices with respect to time in the area, and, for each one of a plurality of segments of the electronic map; identifying a set of positional data relating to the movement of devices along the navigable element represented by the segment, filtering the identified set of positional data relating to the movement of devices along the navigable element represented by the segment based on mode of transport to obtain one or more subset of the identified positional data relating to the movement of devices along the element represented by the segment which may be expected to relate to traversals of the navigable element for recreational purposes, using the or each obtained subset of the positional data to obtain one or more scenicity parameter which may be used in determining a scenic rating for the segment indicative of a scenicity of the navigable element represented by t

Abstract: There is disclosed herein methods of operating a computing device, such as a server, to associate a hazard with a zone of a digital map. The method comprises the computing device: receiving data representative of a location of a hazard matched to a location on a digital map accessible to said computing device; and determining if the repository comprises data representative of a zone corresponding to a region of a digital map containing the location of the hazard, to which the hazard should be associated. If the repository does not comprise data representative of such a zone, the method further comprises generating data representative of a zone corresponding to a region of a digital map containing the location of the hazard, and storing the generated data representative of said zone in the data repository. There is also disclosed herein computing devices and software for carrying out these methods.

Abstract: Data indicative of a plurality of duration times is obtained, each duration time relating to a dynamic POI of a set of a plurality of dynamic POIs that have a similar location, and are of similar type. Each duration time is in respect of a given time. The data indicative of each duration time is representative of a difference between a time at which the dynamic POI was in an active state and a time at which the dynamic POI was in an inactive state. The obtained duration time data and the associated time data are used to obtain a duration time function indicative of a variation in duration time with respect to time. The duration time function is associated with data indicative of a given geographic location.

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 predefined 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.

Abstract: Embodiments of the present invention provide a method of resolving a point location from a location reference, the location reference comprising a plurality of location reference points, each location reference point being representative of a node in a first digital map and having attributes associated therewith from the first digital map, including geographic coordinates of the node, so as to define a path between a start location reference point and an end location reference point, the location reference further comprising an offset value representative of a distance along the path.
