Abstract This paper describes the development of cybercartography since the introduction of the term in 1997. Although the origins of cybercartography were largely conceptual in nature, the evolution of cybercartography to date has been an iterative process reflecting the creative interplay between theory and practice. A major step forward was made in 2002 when the Geomatics and Cartographic Research Centre at Carleton University received a $2.5 million grant from the Social Sciences and Humanities Research Council of Canada to explore the utility of cybercartography to what was described as the New Economy. By 2006, the interaction between theory and practice had led to considerable advances in cybercartography as a holistic, location-based concept and two new cybercartographic products, the Cybercartographic Atlas of Antarctica and the Cybercartographic Atlas of Canada's Trade with the World, were produced. Between 2006 and 2009, cybercartography was further developed as a result of interaction with indigenous communities, especially in Canada's north and new interactive atlases such as the Kitikmeot Place Names Atlas and the Community Atlas of Arctic Bay were created in cooperation with the communities involved. The Nunaliit Cybercartographic Atlas Framework, built using open source software and open specifications and standards, was developed to facilitate direct input to these atlases. Cybercartography is now entering a new phase in both theory and practice building on a recently completed prototype atlas of Indigenous Perspectives and Knowledge. 相似文献

This article examines the practices and process that (re)produce neighborhoods. I argue that the practices producing neighborhoods in the 1970s inform the practices (re)producing neighborhoods today. Drawing upon Lefebvre's concepts of social space and spatial practice, Bourdieu's concepts of practice and habitus, and Pred's concept of place as a historically contingent process, I examine the (re)production of Milwaukee's Riverwest neighborhood as a process. Practices of institution building and protest were central to the production of this relatively socially inclusive and activist neighborhood. Over the past 30 years, through what could be defined as the habitus of place, the process of neighborhood (re)production continued many of the practices first established in the 1970s, as new practices addressed social and cultural changes. A focus on practices and process draws our attention to the (re)production of a relatively stable, consistent, long-term neighborhood identity. 相似文献
