基于地理实体的道路交通空间数据库设计与建设

道路交通是城市最重要的基础设施,但现阶段道路交通空间数据往往重视空间表达,忽略管理特性,针对上述问题,本文提出基于地理实体的道路空间数据库建设思路。通过分析空间特征、研究数据构成,提出了道路交通实体模型,进行了地理实体空间数据库设计,最后阐述了基于地理实体思想的空间数据建库流程,并探讨了边界确定、交叉口归属等问题的解决思路。     

Digitizing the Dragon Head,Geo-Coding the Urban Landscape: GIS and the Transformation of China's Urban Governance

While local governments have been one of the major user groups of GIS, there is still little research on how GIS development in local government might be intertwined with urban governance, particularly in non-Western contexts. Drawing upon insights from GIS implementation, critical GIS, and governmentality studies, this article seeks to bridge this gap by examining the implications of Chinese urban government GIS practices amidst China's changing urban governance. Through an in-depth case study of Shenzhen, this article analyzes how urban GIS has been transformed from a practice involving internal organizational workflow automation, into a more active dimension of the governance of urban spaces—reflected in the expanding practice of “geo-coding” the urban landscape. “Geo-coding” here refers to a broadly defined spatial practice of carving and reconstructing a rational urban space. GIS practices have constituted a particular form of geographic rationality that seeks to govern at a distance while simultaneously regulating the urban environment, intersecting with the broader transformations of China's urban governance. These GIS developments have been largely government-centric rather than citizen-centric, yet they provide possibilities for new forms of spatial knowledge production for citizen participation in urban governance.
