The true cost of spatial data in Canada   总被引:2,自引:0,他引:2  
The evolution of the Information Age, in Canada, has meant an unheralded parallel social evolutionthe development of a class structure, if you will, that is tied to data accessibility. While other countries have made data freely available for use by industry, education and the public, Canada has opted to follow a restrictive data policy under which data are essentially available to a select fewthose who can afford the prices. While anyone can purchase the data, not everyone can pay the price. The implications of this in our society are immense and are felt throughout our social structures. One obvious example of this is the lack of quality, high‐resolution Canadian data freely available for use in the Canadian education system, particularly in the university classes in which students today are usually introduced to GIS, visualization and data interpretation. Our students have data to work with, but often they are the freely available American data. They learn from examples derived in the mountains of Wyoming or the forests of Washington. How did this Canadian data restriction happen? In this paper, the evolution of GIS classicism is explored through examination of the evolution in Canada of GIS itself. The data situation elsewhere in the world is reviewed, the feasibility of ‘freeing’ data is discussed and a call for a radical change in the way data/information are handled in Canada is presented.  相似文献

Teaching of critical spatial thinking in higher education empowers graduates to effectively engage with spatial data. Geographic information systems (GIS) and science are taught to undergraduates across many disciplines; we evaluate how this contributes to critical spatial thinking. The discipline of GIS covers the whole process of spatial decision-making, but GIS modules often ignore the context setting of spatial problems, and just cover the technical aspects of how to use GIS software. We outline how some existing GIS practicals could be improved to focus on the development of critical spatial thinking skills, competences and abilities that are valuable to graduates.  相似文献

This article reports on a continuing project which has developed a major reconceptualization and revision of how borders may be seen and measured through the use of GIS. Using the data layers of the ARC/INFO GIS system, a new dataset has been developed which allows analysts to talk about the specific qualities of borders in terms of opportunity and willingness, that is, the ease of interaction and salience, respectively. The theory and method behind this reconceptualization is described. The results are represented both in visual terms—maps—and through the use of a quantitative dataset which lets us go beyond simply observing the number of borders a state possesses, whether or not a border existed between two states, or the length of that border. The dataset is presented and discussed, as well as preliminary analyses of the borders of conflict dyads from three separate conflict datasets. The basic ‘interaction opportunity’ model that underlies the opportunity and willingness framework is supported.  相似文献

Advocates for geographic information system (GIS) education contend that learning about GIS promotes students’ spatial thinking. Empirical studies are still needed to elucidate the potential of GIS as an instructional tool to support spatial thinking in other geography courses. Using a non-equivalent control group research design, this study examines the effect of using Web-based GIS in a world geography course on the development of students’ spatial thinking abilities. The findings indicate that Web-based GIS activities implemented in this study significantly enhanced students’ spatial thinking skills.  相似文献

It is the overall aim of this article to investigate theoretically how spatial embeddedness of learning and knowledge creation might be challenged by alternative organisational forms (i.e. temporary organisations). The article presents development coalitions as an alternative to projects as a form of temporary organisation. They are potentially able to combine the promotion of radical change with collective and localised learning, thus eliminating some of the characteristic shortcomings of project organizations with regard to collective learning and transfer of knowledge.  相似文献

This paper presents four ‘knowledge maps’ or ‘schemes’ which can be used as aids to knowledge management in spatial planning. The schemes relate to the four dimensions of knowledge, i.e. content, sources, application and methods. The schemes are based upon theoretical considerations as well as on practical experience with knowledge management for planning projects, some examples of which are given. They are, furthermore, tested in various ways as to their usefulness. Their primary purpose is, in fact, to make aspects of knowledge management which in practice are often applied in an intuitive manner more explicit, and thus to enhance their reliability.  相似文献

According to Bruno Latour, the imposition of crude classificatory schemes onto complex entities has two main effects: firstly, the classifications lead social actors to sift the world into the schemes' simple categories; secondly, underlying relations subvert the schemes' functioning, resulting in the production of transgressive 'hybrids'. Thus, classification and relation interact and this interaction shapes both the practice of classification and the world that is classified. In this paper, we examine the interaction between a scheme of spatial classification and the spaces that are enrolled within the scheme. We show that a division between urban and rural areas was put in place in post-war England in order to protect a 'vulnerable' rural nature from urban advance. However, as soon as it was imposed, this division was transgressed by complex socio-economic processes. We assess the response to this transgression by considering the activities of the Council for the Protection of Rural England (CPRE), an environmental group that played some considerable part in constructing the urban–rural divide in the first place. We show that the CPRE has responded to the 'paradox of preservationism' by placing urban–rural divisions in the context of 'ecological' relationships. We illustrate this 'ecologization' of the modernist divide using the example of housing and we argue that the CPRE's ecological approach illustrates how a new alignment between 'urban' and 'rural' may herald a new and more sophisticated form of spatial classification.  相似文献

Knowledge has become a key source of competitiveness for advanced regions and nations, indicating a transformation of capitalism towards a “knowledge economy”. Knowledge intensive sectors in production and in services have a lead in this respect, they can be considered as role models for the future. The innovation process, the mechanisms of knowledge exchange and the respective linkages in those industries differ quite markedly from those in other sectors. Clustering and local knowledge spillovers are frequently stated phenomena, although it is still unclear as to what the nature and geography of those knowledge links are. The aim of this paper is to examine the character of the innovation process and the type of interactions in those industries, in order to find out how strongly they are related to regional, national and international innovation systems. We will analyse the sources and the mechanisms of knowledge exchange and their relevance for innovation. The paper develops a typology of innovation interactions and provides empirical evidence for Austria based on data from a recent firm survey.  相似文献

The arrival of the term Geographical Information System (GIS) in the 1960s soon created a demand for training and education in the use of this specialist hardware and software. Initially the main focus was on training people to use GIS, formal named degree programmes leading to postgraduate and undergraduate qualifications arrived later. This paper explores the changing landscape of U.K. degree level GIS education drawing on contemporary information from Higher Education Institution websites and a case study of the first single honours degree in GIS in Europe. The paper identifies a rise and fall in the number of named undergraduate “GIS” degrees since the late 1980s sandwiched between the continuation and development of postgraduate qualifications. In parallel with this trend the teaching and learning of GIS skills has emerged as a core component of undergraduate degree programmes with “Geography” in their title and in national school and degree level benchmarking statements for the discipline.  相似文献

Once confined to paper, national cartographic projects increasingly play out through spatial data infrastructures such as software programs and smartphones. Across the Global South, foreign donor-funded digital platforms emphasize transparency, accountability and data sharing while echoing colonial projects that consolidated state-based territorial knowledge. This article brings political geography scholarship on state and counter-mapping together with new work on the political ecology of data to highlight a contemporary dimension of territorialization, one in which state actors seek to consolidate and authorize national geospatial information onto digital platforms. We call attention to the role of data infrastructures in contemporary resource control, arguing that territorializing data both extends state territorialization onto digital platforms and, paradoxically, provides new avenues for non-state actors to claim land. Drawing on interviews, document review, and long-term fieldwork, we compare the origins, institutionalization and realization of Indonesia and Myanmar's ‘One Map’ projects. Both projects aimed to create a government-managed online spatial data platform, building on national mapping and management traditions while responding to new international incentives, such as climate change mitigation in Indonesia and good democratic governance in Myanmar. While both projects encountered technical difficulties and evolved during implementation, different national histories and political trajectories resulted in the embrace and expansion of the program in Indonesia but reluctant participation and eventual crisis in Myanmar. Together, these cases show how spatial data infrastructures can both extend state control over space and offer opportunities for contesting or reimagining land and nation, even as such infrastructures remain embedded in local power relations.  相似文献

New advances in computer science address problems historical scientists face in gathering and evaluating the now vast data sources available through the Internet. As an example we introduce Dacura, a dataset curation platform designed to assist historical researchers in harvesting, evaluating, and curating high-quality information sets from the Internet and other sources. Dacura uses semantic knowledge graph technology to represent data as complex, inter-related knowledge allowing rapid search and retrieval of highly specific data without the need of a lookup table. Dacura automates the generation of tools to help non-experts curate high quality knowledge bases over time and to integrate data from multiple sources into its curated knowledge model. Together these features allow rapid harvesting and automated evaluation of Internet resources. We provide an example of Dacura in practice as the software employed to populate and manage the Seshat databank.  相似文献

This paper aims at a greater comprehension of the distribution of differentiated knowledge bases and their association with innovation performance. Drawing on evolutionary economic geography, we applied a combinatorial and dynamic view on knowledge bases. The main contribution is the examination of changes and transformations of knowledge bases over time in particular group of regions in Europe and links with innovation performance. Our study revealed systematic regularities between regions with different innovation performance and their knowledge bases. With decreasing regional innovation performance the volatility of knowledge bases over time increases. Innovation leaders evinced stability over time and the most balanced composition of knowledge bases (compared with Central and Eastern Europe regions). Western European countries and regions exhibit the most balanced structure of knowledge bases. An important complementarity and synergy has been identified in the close relatedness of the symbolic knowledge base to the analytical knowledge base. The highest intensity of SME cooperation takes place in regions with a strong analytical base and in regions with the most balanced mix among all three bases (particularly in the UK, the Netherlands and Belgium. Underperforming in innovation show a balanced mix of synthetic and symbolic knowledge bases.  相似文献

High levels of survey nonresponse potentially produce unreliable data due to the often indeterminable possibility of such data being subject to nonresponse bias. In this paper, spatial patterns of global nonresponse rate are analyzed in order to identify whether systemic bias exists across urban spaces with regard to survey nonresponse. Forward stepwise regression is used in combination with spatial regression analysis to build models enabling the prediction of global nonresponse rates in the voluntary 2011 National Household Survey based on explanatory employment, housing, income, and other variables within 11 Canadian cities. The modelling process underscores the inequity of global nonresponse rates; places with high unemployment, high rates of rental properties, a higher proportion of Aboriginal residents, and lower educational attainment have lower compliance with the voluntary survey. Such a pattern has the potential to dramatically influence the ability of government, non-governmental organizations, and other service providers to address the needs of residents of such urban areas.  相似文献
