自然资源一体化政务服务系统及数据融合建设——以南京为例     

陈波  崔蓓  丁鑫 《测绘通报》2020,(12):75-78

自然资源部制定的信息化建设总体方案中，要求构建“互联网+自然资源政务服务”应用体系，实现“服务事项标准统一、整体联动、业务协同，自然资源政务服务和共享开放能力全面提高”。一体化政务服务系统作为政务服务应用体系的重点建设内容，也是落实自然资源管理“两统一”职责的重要支撑，如何整合各类数据资源、发挥系统作用，成为亟待研究的问题。本文在分析自然资源业务管理需求后，提出了一体化政务服务系统及数据融合的建设思路。  相似文献   

Contribution of the SISCam Web-based GIS to the seismotectonic study of Campania (Southern Apennines): an example of application to the Sannio-area     

Rosa Nappi  Giuliana Alessio  Giovanni Bronzino  Carlo Terranova  Giuseppe Vilardo 《Natural Hazards》2008,45(1):73-85

In this article the implementation and potential of the Seismotectonic Information System of the Campania Region (SISCam) are described, in particular an application of this Web-based GIS system to the seismotectonic analysis of the Sannio area (Southern Apennines) is performed. WEB-GIS technologies greatly contribute to both the environmental monitoring and the disaster management of areas affected by high natural risks. Specifically the SISCam system has been developed with the aim of providing easy access and fast diffusion, through Internet technology, of the most significant geological, geophysical, and territorial data relative to the Campania Region. The Sannio area has been selected as our application example because it is among the most active seismic regions in Italy. This portion of the Southern Apennines which was hit by the June 5, 1688 strong earthquake (M _W = 6.7, CPTI 1999) and by some low- and moderate-energy seismic sequences (1990–1992, 1997), is characterized by a complex inherited tectonic setting and low-tectonic deformation rates that hide the seismogenic sources position. Since this case study turned out to be complicated, the use of the SIScam WEB-GIS has become indispensable because it allowed us to visualize, integrate and analyze all the data available, in order to obtain an accurate and direct picture of the seismotectonic setting of the area. Moreover, a different approach of data analysis was necessary, due to the lack of up-to-date neotectonic and structural data; therefore, the operation of this GIS system enabled us to process and generate some original informative layers, through image analysis, such as new structural lineaments represented on a map of the potential active faults of the area, which has been the final result of our application, as a contribution to new knowledge about the local seismic risk parameters.  相似文献   

The Potential of Maps APIs for Internet GIS Applications   总被引：2，自引：0，他引：2  

T Edwin Chow 《Transactions in GIS》2008,12(2):179-191

Since the launching of Maps Application Programming Interfaces (APIs) in 2005, many web developers, including geographers and non‐geographers, applauded the freely adaptable tools and used them to spawn numerous Internet applications. The success of the Maps APIs is largely attributable to its no‐cost policy, the availability of global data coverage, dynamic navigation, query capability, and ease of implementation. Despite its versatility in dynamic exploration of geographic data online, the existing Maps APIs lack Geographic Information System (GIS) functionalities compared to other Internet Mapping Services. The goal of this research was to review the potential of the Maps APIs for Internet GIS applications. This research employed the Google Maps API and developed a web prototype that disseminates spatial information of urban sprawl in Mundy Township, Michigan. The results revealed that both vector and raster data could be effectively represented by using the Maps API. Moreover, the Geographic Markup Language (GML) approach illustrated great potential for developing Internet GIS solutions around open specifications. This research suggested several potential solutions to expand the spectrum of GIS operations of the Maps APIs by incorporating the XML‐related technology and extending the JavaScript library.  相似文献

Virtual vegetables and adopted sheep: ethical relation, authenticity and Internet-mediated food production technologies   总被引：2，自引：1，他引：2  

Lewis Holloway 《Area》2002,34(1):70-81

Associating ideas related to cultural geographies of 'quality' food production and consumption with recent discussion of Internet technologies, virtuality and simulation, this paper examines two newly constituted Internet enterprises offering customers 'virtual' experiences of food production, and 'quality' food products in which they have invested. The paper shows how these enterprises are associated with particular types of geographical and ethical relation, and a search for 'authentic', connected, relationships with food, farming, locality and 'nature'. These relationships are constituted in an assemblage of things held together by flows of food, products, money and electronic communication. The paper ends by suggesting a number of theoretical ideas that might usefully be explored in empirical research into Internet-mediated food production.  相似文献   

Digital effects in the spatial economy of film: towards a research agenda     

Andrew Currah 《Area》2003,35(1):64-73

A new assemblage of digital technologies, organized around compressed software formats and broadband Internet infrastructures, is reconfiguring the motion picture industry. In this paper, I review the impacts of digitization upon the spatial economy of film in the United States via a commodity chain framework. The discussion raises some important themes for conceptual debate in economic geography.  相似文献

COUNTERHEGEMONIC DISCOURSES AND THE INTERNET     

BARNEY WARF  JOHN GRIMES 《Geographical review》1997,87(2):259-274

ABSTRACT. Contrary to much of the hype that posits cyberspace as the uncontested domain of rugged individualists, computer networks and traffic exhibit deeply social and political roots. The Internet is neither inherently oppressive nor automatically emancipatory; it is a terrain of contested philosophies and politics. After a brief review of the politics of electronic knowledge, we discuss the ways in which the Internet can be harnessed for counterhegemonic (antiestablishment) political ends. We focus on progressive uses, including the confrontation of nomadic power and rhizomic power structures, in which the local becomes the global. We also offer an encapsulation of right-wing uses. Throughout, we see cyberactivism as a necessary, but not sufficient, complement to real-world struggles on behalf of the disempowered.  相似文献
