In at least one embodiment, the method has the following actions: a) accessing a 3D model with 3D objects 5 b) showing on the display a graphical display of one or more scenes comprising a moving view on one or more of the 3D objects as seen from a certain moving point of view, the one or more 3D objects comprising at least one advertisement space, the at least one advertisement space having an advertisement space location and an advertisement space size, c) receiving a message inclusive of message data and message location data, and d) in dependence on a distance between the moving point of view and the one or more 3D objects, mapping the message data on the at least one advertisement space if the advertisement space location is associated with the message location data such that the message data overlays the advertisement space in the display.

Abstract: A method for determining vehicle priority settings (30) at an intersection (26) is provided comprising accumulating probe data (24) from a plurality of individual navigation units (20). An intersection within a digital map (14) is selected, and a plurality of probe traces (32) are selected. The probe traces (32) are processed in a method characterized by selecting a pair of probe traces (32) that enter the intersection (26) at the same time on different trajectories (34). It is determined which of the probe traces (32) proceeds through the intersection first and an intersection priority matrix (36) is updated accordingly. This intersection priority matrix (36) is utilized to formulate at least one derived intersection priority setting (38).

Abstract: A method for determining barrier crossing information for convoyed objects (22) using historic trajectory data (28). Trajectories (28) having similar geographical and directional properties are bundled so that trajectory density can be measured as a function of position and time (s, t). Visual presentation of the trajectory information can be used to determine certain types of barrier crossing information useful in a digital map. Frequency analysis on a number of trajectory density time series may be performed to determine specific barrier crossing locations (26) through the detection of vehicle bursts. Such frequency analysis may also indicate barrier crossing times and schedules in the case of crossing patterns.

Abstract: An outdoor-to-indoor (and vise versa) navigation system guides a traveler (30) to an interior point of interest (POI, 28) inside a three-dimensional structure (16) using a navigation device (10). When the traveler (30) reaches the destination (16) address, a 3D model of the destination object (16) is rendered on a display screen (12) and subsequent navigation assistance is rendered in relation to attributed features associated with the 3D model. Initial directional cues (33) associated with the 3D model guide the traveler (30) in relation to externally discernable POIs and toward an exterior portal POI (24). When the current position of the navigation device (10) generally coincides with the exterior portal POI (24), a set of final directional cues (35) are rendered which lead the traveler (30) in relation to internally discernable POIs to an interior feature POI (28). 3D navigation attributes may be associated with various POIs and used in the 3D portion of the navigation routing program.

Abstract: A method for realigning network elements in a digital map based on a new data set using active contour manipulation techniques. The active contour optimization process is controlled so that certain desirable features in the original shape of the active contour(s) are not distorted. In the case of network features which may be represented by two or more open active contours, the active contours are coupled prior to optimizing so that the original desirable shape, e.g., the parallel spacing of lanes in a dual carriageway road, may be maintained during the optimization process. In the case of certain closed active contours, for example roundabout geometries, a single closed active contour may be coupled to itself by linking its control points one-to-another and maintaining a proportional direction and distance movement during the optimizing process. As a result, data base networks can be assessed and aligned with less difficulty and geometric distortion.

Abstract: A method of identifying a temporarily located road feature that engenders vehicular speed behavior change comprises a navigation apparatus monitoring speed thereof or a parameter associated therewith. The method also comprises the navigation apparatus generating a message in response to detection of a profile associated with speed of the navigation apparatus and that corresponds to a predetermined speed change profile associated with the presence of the temporarily located road feature.

Abstract: A method and system for generating map data is disclosed, wherein the map data represents the inside of a building and/or an enclosed and/or covered area. Location related data is firstly generated by a plurality of mobile devices using at least one non-GPS navigation sensor and at least one GPS sensor, preferably in each mobile device. The location related data is then aggregated and map data determined from the aggregated data.

Abstract: A computerised method of creating map data from a plurality of trips where each trip comprises position data derived from the positions of at least one navigation device over a period of time, the method comprising using a processing circuitry to perform the following steps: i. processing the position data; ii. calculating, from the processing of the position data, trip terminal positions at which the navigation device started to generate positions and/or stopped generating positions and which provide an end point of a trip; iii. performing statistical analysis on the terminal positions in order to determine origin locations at which trips commonly terminate and/or originate; iv. generating further map data, which comprises the origin locations.
