| Abstract: | As an important form of GIS digital products,the data quality of DLG products is to ensure system reliability and effectiveness.The paper discussed the influential factors of DLG product quality,Further more,it applied the method of fuzzy and comprehensive evaluation based on fuzzy Gravity-Center to DLG product quality,which,in some degree,could resolve the information missing problem of traditional fuzzy and comprehensive evaluation.It would make the evaluation method more effective and feasible,and the ev... |
