Abstract

Firstly a formalized represent model of indeterminate geographical objects is designed based on the quartuple (x, y, A, μ). Then a direction reference framework is constructed by revising the cone method for uncertain direction relation presentation, where the partition of direction sections is smoothly and continually, and the two neighboring sections are overlapped in the transition zones with fuzzy method. Based on these, a fuzzy description model for indeterminate direction relation is proposed with the fuzzy directional reference frame where the uncertainty of all the three parts (source object, reference object and reference frame) is taken into account simultaneously. In the end, a case study is implemented to test the rationality and viability of the model.
