【摘要】 GIS已经发展成为一种产业。与其它工业产品一样，GIS产品也必须有质量管理和质量控制，使未来的GIS在向用户提供产品的同时，附带提供该产品的质量指标。在GIS图形中，质量信息的封装存储是质量分析、研究和表达的基础，只有将质量信息与图形的各种信息有机结合在一起，才能对图形质量做进一步的分析、表达。本文从独立封装、实时查询分析入手，探讨了GIS环境下面向地理特征的图形信息封装、查询分析方法，使位置信息与属性信息，定位信息与定位精度信息，信息存储与信息可视化有机结合在了一起。 随着GIS的普及与应用，GIS的可视化问题日益突出，现有的方法已不能满足要求，需要从可视化的理论基础、理论模型等方面进行改进，才能使可视化技术得以根本提高。可视化涉及多学科，多门类的知识。拓扑关系(空间、时间拓扑)是制约可视化的关键技术之一，设计一个适合于GIS可视化要求的空间、时间拓扑模型关系到GIS可视化的更进一步发展。为此，本文设计了基于空间坐标的N4I空间拓扑模型，并给出了模型矩阵构建算法。同时，为了促进时空GIS(TGIS)的发展，提出了时间拓扑模型—时段拓扑模型的设想，并进行了模型的构建，模型矩阵特征的证明等，在最后还将模型应用到了TGIS系统分析中。更多还原

【Abstract】 GIS has already developed into a kind of industry. Like other industrial products, GIS products must have quality management and quality control, which make GIS can offer user quality index while offering its products in the future. In GIS, quality information encapsulation is the foundation of the quality analysis, study, and express. We could make a future analysis of the quality only through the organic combination of the quality information with various other information of a map object. From the independent encapsulation, real-time query, and dynamic analysis, the paper describes the information encapsulation, information query, and error analysis facing the geographic feature under GIS environment. So the position information, attribute information, and accuracy information will be combined together. That is called the organic combination of information store and information visualization.With the popularization and application of GIS, the visualization problems in GIS are outstanding day by day. Because existing approaches of visualization can’t meet the demands of user, we need to improve our visualization technology from its theoretical foundation and theoretical model, etc. Only by this way, could we improve our visualization technology at all. Visualization in GIS relates to kinds of disciplines and much knowledge. Topological model is one of the key technologies in GIS visualization. It is favorable to GIS visualization to design a topological model of space and a topological model of time that could meet the demands of GIS visualization. For this reason, the paper describes a N4I topological model of space based on spatial coordinates, at the same time, proposes an Algorithm to form the model Matrix. For the development of temporal-spatial GIS, the paper proposes a temporal-subsection topological model, and completes the identification of its characteristic. Finally, the paper applies the temporal-subsection topological model to the temporal analysis of TGIS.更多还原
