Abstract: Disclosed herein is a technique for obtaining information relating to a navigable network from devices (12) that are associated with users travelling within the navigable network. For example, a central server can issue requests to the devices (12) for automatically obtaining sensor data, with a request including a set of instructions for obtaining sensor data from one or more sensor(s) (13) accessible by the device (12). The request also includes a location-specific trigger. Thus, when it is determined that the device (12) has reached the location associated with the trigger, the device is able to automatically action the instructions in order to obtain the requested sensor data, which can then be reported back to the server.

Abstract: Embodiments of the present invention provide a method of providing data associated with a point of interest (POI), comprising determining, based on a location of a POI, a portion of digital map data of a geographic region, said digital map data comprising a plurality of segments representing navigable elements of a navigable network within the geographic region, and generating POI-map data associated with the POI indicative of at least some segments within the portion of digital map data.

Abstract: Embodiments of the present invention provide a method of providing information associated with a point of interest (POI), comprising: communicating location information indicative of a determined geographic location of a portable device to a server computer; receiving at least one POI-map from the server computer based on the location information, wherein each POI-map is associated with at least one POI and comprises segments representative of navigable elements of a navigable network; determining a segment of a received POI-map corresponding to the determined geographic location of the portable device; and outputting a notification associated with a POI of the received POI-map based on the navigable segment.
