Fuzzy overlay analysis model based on Flou sets
基于Flou集的模糊叠置分析模型

The method described the fuzzy regions using Flou sets. Then it proposed an overlay analysis model of fuzzy raster map layers based on Flou sets. The model could complete general fuzzy overlay and weighted fuzzy overlay. The fuzzy overlay model could avoid the difficulty in dealing with the relations between fuzzy spatial objects through using fuzzy sets to represent the fuzzy region, and the fuzzy overlay result accord with the cognitive principle of people. The practical case shows that this model can well solve fuzzy overlay analysis between the map layers described as Flou sets.
