DLG数字产品的质量评定研究

随着信息化的发展,地理信息数字产品的质量特点发生了质的变化,如何科学评定DLG数字线划图的质量是本文探讨的重要问题。本文提出应用模糊数学理论,用模糊综合评价法评定DLG数字产品的质量,并且建立了该方法的数学模型,确定了质量评价体系的指标因素和权重等。结合具体实例详细阐述了DLG数字线划图的模糊综合评价方法,进一步验证此方法行之有效。

The Quality Assessment Research of DLG Digital Products

With the development of the information technology,the quality characteristics of digital geographic information products have undergone a qualitative change.The scientific assessment of the quality of DLG is the important issue discussed in this paper.This paper puts forward the application fuzzy mathematical theory and assesses the quality of DLG digital products with a fuzzy comprehensive evaluation method.What’s more,this paper establishes a mathematical model of this method and identifies the indicators and weights of quality evaluation system and etc.With concrete examples,it also elaborates on the fuzzy comprehensive evaluation method of DLG and further validates this method to be effective or not.
