Abstract: A route followed by a person is managed. A data store is configured to store data streams corresponding to different kinds of information of a route followed by a person. Data output means is operable to output the data streams to a user such that they are co-related to the route followed by the person. Data handling means is operable to provide the stored data streams to the data output means. The data streams correspond to different route information and can be cross referenced. The data handling means is operable to provide a first data stream and further data stream in a predetermined manner to the data output means and in dependence upon the cross-referable data such that the first and further data streams are output by the data output means in a substantially co-related manner.
