Abstract: A map having surfaces that are depicted at different levels that are not related to topography, with boundaries between the surfaces, where the boundaries are disposed at travel ways. The travel ways form cliff faces in the map between the surfaces, with information items disposed on the cliff faces at positions corresponding to items of interest at locations along the travel ways where the information items are disposed.
