Uncertainty Description of GIS Attribute Data in Hierarchical Approximate Space
GIS attribute data is the property of GIS entity, it has fuzziness and uncertainty. The binary relation for GIS entity object and attribute is meet to the property for approximate space. We choose the object and attribute of GIS information system in our study, use lattice concept, and we think the GIS entities can form partial order relation, and lattice(P(A), ) can form one complete partial order lattice. GIS entities can form hierarchical approximate space in subsection space relation, and the knowledge granularities are thining along with the increasing of attribution.
