互联网全息位置地图迭加协议与建模制图技术 　　摘 要：通过该年度的研究，对全息位置地图的内涵、技术体系有了更清晰准确的认识，并在若干技术层面取得了进展。 研究了全息位置地图的理论框架，对全息位置地图的概念、特征进行了分析，对全息位置地图的制图模型开展了研究。构建了全息位置地图的情境模型和统一数据模型，提出了活动模型、行为模型、情境信息模型组成的三层全息位置地图情境模型，建立了由活动规则、行为规则、情境信息规则组成的逐层推理机制。通过对上海试验区的数据分析，在该年度内重点研究了多种语义位置描述模型，以及信息存储数据模型，特别对室内空间数据模型进行了详细讨论。对多尺度转换、基于地图空间密度分布的网络拓扑地图变比例尺可视化、基于语义的室外场景三维重建等全息位置地图制图关键技术进行了研究，完成了室外街景全景位置数据采集总体集成、互联网位置服务信息挖掘系统的研发，设计了全息位置地图快速制图系统的总体框架与核心模块，设计并初步构建了基于移动平台的室内数据采集系统。 　　关键词：全息位置地图 情境模型 统一数据模型 语义位置描述模型 多比例尺转换 三维重建 　　Abstract： Through the research of last year， subject team had more clear and correct recongnization of the meaning and technology system of panoramic location map， had progresses in some technology problem. The theoretical framework of panoramic location map had been researched. Subject team analysed the conception and character of panoramic location map. The mapping model of panoramic location map had been researched. The context model and uniform data model of panoramic location map had been created. The panoramic location map model which consist of activity model， action model and context model had been brought forward. Subject team had constructed reason regulation faced multi-layer which consist of action regulation， activity regulation and context information regulation. Through anlysing data of test region in Shanghai， multi-semantics location represention model had been reaserched with dominant emphasis. Information storing model， especially indoor space data model had been discussed detailedly. Multi-scale transforming， topology map of networks visualization for scale-variable based on density distribution of map space， 3D reconstruction of outdoor based on semantics had been reaserched. Panoramagram data of streetscape collection system and information mining system of Internet location service had finished. Subject team designed framework and kernel module of panoramic location mapping-rapiddly. Data collection system of indoor based on mobile platform had been constructed pre
