Abstract: A computerised method of allowing one or more users to access information is disclosed. The method includes causing a first computing device to transmit data representing a map to a remote computing device for display to a user thereof and receiving at the first computing device area-data defining a user defined area, relative to the map, wherein the area has associated therewith one or more user-defined parameters that hold for that area. The method further includes causing the first computing device to process the area-data and to link areas having the same, or at least similar, user-defined parameter associated therewith thereby building up a network of areas having the same, or at least similar, parameters and allowing the or each user to access the network of areas, by obtaining data from the first computing device, to obtain information about any one or more of the areas and/or of the network.
