摘　　要：地理信息服务在众多领域中均有着极为重要的地位,地理信息服务对卫星影像数据的需求也在不断增长,如何从众多卫星影像源数据中进行优化选择成为关键问题。本研究构建了以卫星参数、数据完整性、时效性和获取成本为评价指标体系的地理信息服务卫星影像源数据优选评估指标体系。利用层次分析法明确主观权重、变异系数法获取客观权重,然后通过博弈论将主客观权重进行综合优化,最后采用TOPSIS评估法对影像源数据进行排序评估。通过详细的理论阐述、方法步骤解析以及示例数据计算,为卫星影像源数据优选决策提供科学、系统且有效的方法依据,通过实例分析验证了该体系的有效性,旨在为地理信息服务领域卫星影像源数据的合理选择提供科学依据与决策支持。Geographic information services hold a critically important position across a broad spectrum of fields,and the demand for satellite imagery data within these services is continually on the rise.Con-sequently,the challenge of optimizing the selection from anextensive array of satellite image source data has emerged as a pivotal concern.This research endeavor has devised a comprehensive eval-uation index system tailored for satellite image source data in geographic information services,en-compassing satellite parameters,data integrity,timeliness,and acquisition cost as core evaluation indices.The Analytic Hierarchy Process is employed to ascertain subjective weights,while the coef-ficient of variation method determines objective weights.Subsequently,game theory is harnessed to integrate these subjective and objective weights.Ultimately,the Technique for Order Preference by Similarity to Ideal Solution evaluation method is adopted to rank and appraise the image source data.Through rigorous theoretical exposition,methodological step-by-step analysis,and sample data computation,this study furnishes a scientific,systematic,and efficacious methodological frame-work for optimal decision-making concerning satellite image source data.The efficacy of the pro-posed system is substantiated through case analysis,ultimately aiming to provide a robustscientific foundation and decision-making support for the judicious selection of satellite image source data within the realm of geographic information services.
