Studied of spatio-temporal GIS and its application to urban geography

本文研究了具有时间维的地理信息系统，并实现了其在城市地理数据库中的应用。这些应用包括城市活动的短期即昼夜变化和城市化和郊区化的长期变化的主题。利用出行调查数据研究昼夜变化，利用人口普查数据研究长期变化，并探讨了将时间维纳入GIS的概念性研究。对G.Langran（1992）和辛顿提出的概念进行了检验。在这项研究中，栅格数据模型的GIS扩展到时空背景下的“连续体填充模型”。同样，GIS的矢量模型也被扩展到时空背景中，成为一种“边界描述模型”。连续体填充模型适用于允许插值的连续现象，边界描述模型适用于不允许插值的内部均匀现象。本研究中的应用多采用连续体填充模型。

In this study, geographical information systems (GIS) which is capable of incorporating temporal dimension are studied, and their applications to urban geographical databases are implemented. These applications include subjects on short-term I.e. circadian change in urban activity and long-term change of urbanization and suburbanization. Data from person-trip survey for circadian change, and population census data for long-term change are used.In addition, conceptual studies on incorporating temporal dimension into GIS are explored. Concepts presented G.Langran (1992) and Sinton are examined. In this study, raster data model of GIS is extended into the spatio-temporal context as a 'continuum filling model'. In the same way, vector model of GIS is extendedinto the spatio-temporal context as a 'border describing model'. It is argued that continuum filing model is pertinent to continuous phenomena that permit interpolation, and that border describing model is pertinent to internally homogeneous phenomena that don't permit interpolation. Applications in this study mostly adopted continuum filling model.
