TL;DR: In this paper, an integrated planning and decision support system is proposed that integrates artificial intelligence technologies and multi-criteria decision methods with a geographical information system for use in routine land consolidation planning as well as for undertaking ex ante evaluations of land consolidation projects.

Journal ArticleDOI
TL;DR: A new ‘global land fragmentation index’ that combines a multi-attribute decision-making method with a geographic information system that outperforms the existing indices in terms of reliability as it is comprehensive, flexible, problem specific and knowledge-based.

TL;DR: The perspective of European National Mapping Agencies (NMA) on the role of citizen sensing in map production was explored and possible priorities for future research and development are identified to help ensure that the potential of VGI in mapping is realized.
Abstract: The perspective of European National Mapping Agencies (NMA) on the role of citizen sensing in map production was explored. The NMAs varied greatly in their engagement with the community generating volunteered geographic information (VGI) and in their future plans. From an assessment of NMA standard practices, it was evident that much VGI was acquired with a positional accuracy that, while less than that typically acquired by NMAs, actually exceeded the requirements of the nominal data capture scale used by most NMAs. Opportunities for VGI use in map revision and updating were evident, especially for agencies that use a continuous rather than cyclical updating policy. Some NMAs had also developed systems to engage with citizen sensors and examples are discussed. Only rarely was VGI used to collect data on features beyond the standard set used by the NMAs. The potential role of citizen sensing and so its current scale of use by NMAs is limited by a series of concerns, notably relating to issues of data quality, the nature and motivation of the contributors, legal issues, the sustainability of data source, and employment fears of NMA staff. Possible priorities for future research and development are identified to help ensure that the potential of VGI in mapping is realized.

TL;DR: The system's structural framework is outlined and the core land redistribution sub-system called LandSpaCES (Land Spatial Consolidation Expert System) is exemplified using a case study to indicate that the results provide a close fit to those derived by independent human experts.
Abstract: This paper introduces a new planning support system currently under development for land consolidation in Cyprus called LACONISS (LAnd CONsolidation Integrated Support System). The system's structural framework is outlined and the core land redistribution sub-system called LandSpaCES (Land Spatial Consolidation Expert System) is exemplified using a case study. Model evaluation indicates that the results provide a close fit to those derived by independent human experts. Alternative solutions are generated under different evaluation scenarios and sensitivity analysis is used to examine the weights and performance scores of the criteria involved in the process.

TL;DR: In this article, the authors developed the concept and connotation of rural spatial restructuring, and analyzed the effects of industrialization and urbanization on rural production, living and ecological space by carrying out land consolidation, so as to establish a new platform for building new countryside and realizing urban-rural integration development in China.
Abstract: The implementation of new type industrialization and urbanization and agricultural modernization strategies lacks of a major hand grip and spatial supporting platform, due to long-term existed "dual-track" structure of rural-urban development in China as well as un- stable rural development institution and mechanism It is necessary to restructure rural pro- duction, living and ecological space by carrying out land consolidation, so as to establish a new platform for building new countryside and realizing urban-rural integration development in China This paper develops the concept and connotation of rural spatial restructuring Basing on the effects analysis of industrialization and urbanization on rural production, living and ecological space, the mechanism of pushing forward rural spatial restructuring by carry- ing out land consolidation is probed A conceptualization of the models of rural production, living and ecological spatial restructuring is analyzed combining with agricultural land con- solidation, hollowed villages consolidation and industrial and mining land consolidation Fi- nally, the author argues that a "bottom-up" restructuring strategy accompanied by a few "top-down" elements is helpful for smoothly pushing forward rural spatial restructuring in China In addition, the optimization and restructuring of rural production, living and ecological space will rely on the innovations of regional engineering technology, policy and mechanism, and mode of rural land consolidation, and more attentions should be paid to rural space, the foundation base and platform for realizing urban-rural integration development

TL;DR: A snapshot of the role of citizens in crowdsourcing geographic information is provided and a guide to the current status of this rapidly emerging and evolving subject is provided.
Abstract: Citizens are increasingly becoming an important source of geographic information, sometimes entering domains that had until recently been the exclusive realm of authoritative agencies. This activity has a very diverse character as it can, amongst other things, be active or passive, involve spatial or aspatial data and the data provided can be variable in terms of key attributes such as format, description and quality. Unsurprisingly, therefore, there are a variety of terms used to describe data arising from citizens. In this article, the expressions used to describe citizen sensing of geographic information are reviewed and their use over time explored, prior to categorizing them and highlighting key issues in the current state of the subject. The latter involved a review of ~100 Internet sites with particular focus on their thematic topic, the nature of the data and issues such as incentives for contributors. This review suggests that most sites involve active rather than passive contribution, with citizens typically motivated by the desire to aid a worthy cause, often receiving little training. As such, this article provides a snapshot of the role of citizens in crowdsourcing geographic information and a guide to the current status of this rapidly emerging and evolving subject.

TL;DR: In this article, a position paper of the International Society for Photogrammetry and Remote Sensing (ISPRS) Technical Commission II (TC II) revisits the existing geospatial data handling methods and theories to determine if they are still capable of handling emerging gespatial big data, synthesises problems, major issues and challenges with current developments as well as recommending what needs to be developed further in the near future.
Abstract: Big data has now become a strong focus of global interest that is increasingly attracting the attention of academia, industry, government and other organizations. Big data can be situated in the disciplinary area of traditional geospatial data handling theory and methods. The increasing volume and varying format of collected geospatial big data presents challenges in storing, managing, processing, analyzing, visualizing and verifying the quality of data. This has implications for the quality of decisions made with big data. Consequently, this position paper of the International Society for Photogrammetry and Remote Sensing (ISPRS) Technical Commission II (TC II) revisits the existing geospatial data handling methods and theories to determine if they are still capable of handling emerging geospatial big data. Further, the paper synthesises problems, major issues and challenges with current developments as well as recommending what needs to be developed further in the near future.
