Formalized Description of Indeterminate Geographic Object Based on Fuzzy Degree

This paper designs a formalized description model based on the quartuple( x,y,A, D ;, which integrates the positional and thematic uncertainties of the fuzzy point, fuzzy line and fuzzy region. On the basis of the model, this paper gives a case of the site selection of real estate development to test that the representation method is apt for fuzzy analyses and computation.
