Evaluation Model of Digital Map Quality Based on Cloud Model
Guo Hai-tao · 2008
With the broad application of digital map,its quality have drawn more and more attention.In the paper,a comprehensive evaluation method of the digital map quality was presented based on cloud model by using the mapping between qualitative and quantitative knowledge of the cloud model.This paper used the theory of virtual cloud which included the floating cloud and compositive cloud to calculate the comprehensive result of each layer's quality elements,then obtained the cloud parameters of the finally evaluation.At last the result was described with the digital characteristic figure and the subordinate level,and a quality grade of the product was educed.Testified by the experiment,the finally evaluation was intuitionistic and exquisite,and more likely to be close to the reality.
