针对当前网络地图服务现状,认为在网络地图服务中引入自适应理论与技术是提升地图服务智能水平与服务质量的一个重要途径。在分析地图可视化领域自适应相关研究基础上,立足于自适应环境和主体多元需求的阶段性改变,梳理与客体相应的自适应因素,提出了网络地图服务自适应层次模型。阐明了该模型中5个自适应层次的关键研究内容及其技术要点,进而探讨了网络地图服务自适应的发展方向。
In view of the present situation of Web map service,the introduction of adaptive theory and technology was considered to be an important way to enhance the intelligent level and quality of Web map service.Based on correlative studies of adaptive cartographic visualization system and the phase change of adaptive environments and principal part’s diversified requirements,adaptive factors corresponding object and adaptive levels model of Web map service were studied,then the key research contents and techniques of each adaptive level were illuminated,and finally the future research direction of adaptive Web map service was discussed.
