The praxis and politics of building urban dashboards     

《Geoforum》2016

This paper critically reflects on the building of the Dublin Dashboard – a website built by two of the authors that provides citizens, planners, policy makers and companies with an extensive set of data and interactive visualizations about Dublin City, including real-time information – from the perspective of critical data studies. The analysis draws upon participant observation, ethnography, and an archive of correspondence to unpack the building of the dashboard and the emergent politics of data and design. Our findings reveal four main observations. First, a dashboard is a complex socio-technical assemblage of actors and actants that work materially and discursively within a set of social and economic constraints, existing technologies and systems, and power geometries to assemble, produce and maintain the website. Second, the production and maintenance of a dashboard unfolds contextually, contingently and relationally through transduction. Third, the praxis and politics of creating a dashboard has wider recursive effects: just as building the dashboard was shaped by the wider institutional landscape, producing the system inflected that landscape. Fourth, the data, configuration, tools, and modes of presentation of a dashboard produce a particularised set of spatial knowledges about the city. We conclude that rather than frame dashboard development in purely technical terms, it is important to openly recognize their contested and negotiated politics and praxis.  相似文献   

The concept,key technologies and applications of temporal-spatial information infrastructure     

Chengming Li  Jie Yin  Xiaoli Liu 《地球空间信息科学学报》2016,19(2):148-156

Abstract

Smart city is the development of digital city; as its main supporting technology, the digital city geo-spatial framework has to be upgraded to the temporal-spatial information infrastructure (TSII). First, this paper proposes the concept and basic framework of smart city and defines the concept of TSII – processes, integration, mining analysis, and share time-stamps geographic data – and the related policy, regulations and standards, technology, facilities, mechanism, and human resources. The framework has four components: the benchmark of time and space, temporal-spatial big data, the cloud service platform and the related supporting environment. Second, the temporal-spatial big data and cloud service platform are elaborated. Finally, an application of TSII constructed by the Xicheng District Planning Bureau in Beijing is introduced, which provides a useful reference for the construction of smart city.  相似文献   

Mine your data: open data,digital strategies and entrepreneurial governance by code     

Sarah Barns 《Urban geography》2016,37(4):554-571

Investment in the release of open data has become increasingly central to the implementation of smart city programs by governments around the world. Though originally arising out of a push towards “open government” and the pursuit of more transparent decision-making by public authorities at multiple scales, open data programs have more recently been adopted by municipal governments to support entrepreneurial goals of enhanced competitive positioning and attracting investment. As urban scholars now subject the smart city project to critical scrutiny for its role in advancing urban entrepreneurialism, this article considers the relevance of the open data agenda as it shapes wider understandings of the smart city. In particular, I address the collection of policy practices, aspirations, stakeholders and entrepreneurs active in framing the opportunities and values of open data for urban governments. Both the momentum of support for open data, along with a recent shift in the rhetorical aspirations of the open data movement away from the values of openness and transparency and towards a more confined focus on value generation, raise important critical questions for urban geographers concerned with the nature of urban governance in an age of big data.  相似文献   

“玻璃地球”建设的现状、问题、趋势与对策   总被引：2，自引：0，他引：2  

吴冲龙  刘刚 《地质通报》2015,34(7):1280-1287

"玻璃地球"是地质时空大数据的有效载体,是"数字地球"在地矿领域的体现。国际上"玻璃地球"建设存在的问题主要是缺乏应有的总体规划、顶层设计和协调机制,仅实现了地层框架模型的构建,缺乏多源、多主题信息的混合建模,以及复杂地质结构的快速、动态、全息、精细的多维建模,也未解决多尺度地质框架模型的集成问题。其发展趋势是从个别走向一般,由局部走向整体,从功能走向数据,从零散走向集成,从展示走向实用。由于"玻璃地球"规模大、涉及面广,建设目标与全国地质工作信息化及"智慧地球"一致,有必要从战略上进行统一规划和顶层设计,并把相关的"数字国土"、"数字矿山"、"数字油田"、"数字工程"等纳入到统一的轨道中来。  相似文献   

智慧海洋国际共享应用平台发展趋势及其对策建议          下载免费PDF全文

孙朝辉  李兆钦  刘增宏 《海洋开发与管理》2020,37(1):3-9

当前,我国正在全面开展智慧海洋建设,各种新研发观测平台不断涌现,但是围绕智慧海洋的信息化建设仍显落后,在数据管理、质量控制方法和系统开发等方面与发达国家仍存在较大差距。文章通过分析国内外海洋共享应用平台的发展趋势及其特点,从数据管理方法、质量控制和系统设计开发等多个方面找出差距所在。研究表明,与国外相比,国内存在共享平台业务化运行不多的问题,为实现数据的规范化,并给出尽快制定针对不同观测平台数据管理规范、加强数据质量控制方法研究、加强具备专业知识的系统设计人才培养等建议。  相似文献
