Abstract
Distance-space mapping is to geometrically distort the map such that the Euclidean distance between some points on the map are as consistent as possible with the given distance other than physical distance, e.g., travel time, cognitive distance, etc. The distance-space mapping has been recently expected as an effective tool in GIS environment which visualizes the distance-space constituted by a variety of distance indices other than the physical distance. This paper discusses the limitations of the conventional distance-space mapping procedures and demonstrates that free-network adjustment of trilateration can be a possible technique for distance-space mapping.
