We describe a new approach to representing vague or uncertain information concerning spatial location. Locational information about objects in information space is expressed through various anchoring relations which enable us to state exactly what is known regarding the spatial location of an object without forcing us to identify that location with either a precise region in the embedding space or any precise mathematical construct from such regions, such as rough sets or fuzzy sets. We describe the motivation for introducing Anchoring, propose the beginnings of a formal theory of the anchoring relations, and illustrate some of the ideas with examples typical of the real-life use of GIS.
