The disclosure relates to a method for providing navigation guidance taking into account information received from a plurality of remote data sources, the information comprising time stamped location data. Relevant remote data sources within a geographical area defined for a particular user, e.g. based on their location, can be identified based on the area and a predetermined discrete time interval. These sources then generate reports that are using in providing subsequent navigation data for the user. The remote sources may be electronic sensing devices at a venue and may use, for example, microphones, cameras, accelerometers, chemical, optical or thermal sensors to provide data on how busy a restaurant or nightclub is. They may rely on manual updates by multiple users. The number of, or rate of change of the number of, devices at a venue may be used in determining the geographical area and/or the time interval to be considered. |
