Fuzzy space

Hello everybody,

I am looking for literature about the concept of "Fuzzy space" in G.I.S.
Is there anyone who can give me titles of books or articles on this subject??

Ronald Wiemer, ARCHIS, Amersfoort

I'm not exactly sure what is meant by "fuzzy space" but I have the
following article on my shelf:

  P.A. Burrough (1989): Fuzzy Mathematical Methods for Soil Survey
  and Land Evaluation. J. Soil Sc. 40,477--492.

I can send you a photocopy if it is of any use.
