Abstract: A map or plan of a location is generated from a set of map data, wherein at least some of said map data has a time-dependent status associated therewith. An input time is determined from a user input and said map data is displayed according to its associated time-dependent status on the basis of said input time. When the input time is changed, the map data displayed is changed accordingly.

Abstract: A method of generating a customised map comprises: taking first, map data for generating a map; taking second, asset data, the asset data comprising a plurality of asset locations on the map and the locations having a label associated therewith; and applying the asset data to the map data to produce an initial labelled map. One or more predetermined rules is applied to the labels to determine whether any group of labels on the initial labelled map is in conflict. For those groups of labels determined to be in conflict, an algorithm is applied to move one or more of the labels in the pair or group to remove or reduce the conflict.
