    • Abstract
  • The random uncertainty and fuzziness uncertainty exist in spatial data at the same time.Ant that it is not suitable for using hybrid entropy to deal with the uncertainty of some geographical objects which contain random uncertainty and fuzziness uncertainty.The uncertainty of fuzzy geographical object was discussed by using type-2 fuzzy theory.The error model of membership of vague geographical object was built by using λ-cut of fuzzy set and error band of circle based on positional erros.The measure method of the error of membership was analyzed,Finally,the membership grade error cube was proposed to synthetically describe the uncertainty of fuzzy point.
