Our study focuses on the task of land use evolution in urban environment which is fundamental in revealing the territorial planning. It refers crucially to the use of spatial data mining tools due to their high potential in handling with spatial data characteristics. The results of our knowledge discovery process are spatial and spatiotemporal association rules referring to the land use and its evolution. Three proposals based on different knowledge extraction techniques are detailed. The first approach aims to extract spatiotemporal association rules by introducing time into the attributes. The second approach forecasts the extracted rules at different dates. The third approach is devoted to the mining of spatiotemporal association rules. This proposal looks for rules that relate properties of reference objects with properties of other spatial relevant objects. The extracted patterns are relationships involving the spatial objects during time periods. To prove the applicability of each approach, experimentations are conducted on real world data. The obtained results are promising.
城市环境下的土地利用演变是揭示国土规划的基础。它主要是指空间数据挖掘工具的使用,因为它们在处理空间数据特征方面具有很高的潜力。知识发现过程的结果是指土地利用及其演变的时空关联规则。详细介绍了基于不同知识提取技术的三种方案。第一种方法通过在属性中引入时间来提取时空关联规则。第二种方法预测在不同日期提取的规则。第三种方法致力于挖掘时空关联规则。该建议寻找将参考对象的属性与其他空间相关对象的属性联系起来的规则。提取的模式是在时间段内涉及空间对象的关系。为了证明每种方法的适用性,在真实世界的数据上进行了实验。所得结果是有希望的。

Modeling Environmental Impacts on Viticultural Ecosystems 环境对葡萄栽培生态系统影响的模拟

This paper focuses on simulating environmental impacts on grapevine behavioral dynamics and vineyard management strategies. The methodology presented uses technology from geomatics object oriented databases and spatio-temporal data models. Our approach has two principle objectives, first, to simulate grapevine phenology and grape ripening under spatial and temporal environmental conditions and constraints and secondly, to simulate viticultural practices and adaptation strategies under various constraints (environmental, economical, socio-technical). The approach is based on a responsive agent-based structure where environmental conditions and constraints are considered as a set of forcing data (biophysical, socio-economic and regulatory data) that influences the modelled activities. The experiment was conducted in the regulated wine producing appellation Grand Cru “Quarts de Chaume”, situated in the middle Loire Valley, France. All of the methodology, from the implementation of the knowledge database to the analysis of the first simulation, is presented in this paper.
本文的重点是模拟环境对葡萄树行为动力学的影响和葡萄园管理策略。该方法采用了面向对象的地理信息数据库和时空数据模型技术。我们的方法有两个主要目标,首先,模拟时空环境条件和约束下的葡萄物候和葡萄成熟,其次,模拟各种约束(环境、经济、社会技术)下的葡萄栽培实践和适应策略。该方法基于一种基于反应性主体的结构,将环境条件和制约因素视为一套影响模拟活动的强迫数据(生物物理、社会经济和监管数据)。实验是在位于法国卢瓦尔河谷中部的“Quarts de Chaume”特级酒庄进行的。本文介绍了从知识库的实现到第一次仿真分析的所有方法。

Designing an Information Infrastructure for Policy Integration of Spatial Planning and Flood Risk Management 空间规划与洪水风险管理政策整合的信息基础设施设计
IF 1.4 Q4 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2019-01-01 DOI: 10.4018/IJEPR.2018010104

The policy integration of spatial planning and flood risk management is a promising approach to mitigate flooding. Scholars indicate that the absence of appropriate information base and technological capacity is among the factors impeding this integration. This study found that what needs to be improved is the access to geographic information and geographic technologies by individual policy makers, rather than the ownership of such resources by one organisation as a whole. Based on this finding, we designed the goals and functions for a Spatially Integrated Policy Infrastructure (SIPI) which shares not only geographic information but also models and analysis tools. A prototype of SIPI was also developed as an illustration of the selected functions of this SIPI. The design of SIPI is consistent with other frontier studies and projects in the field of GIS and planning. The development process also provides experience for future studies and development of infrastructures that aim at supporting policy integration.
空间规划与洪水风险管理的政策整合是缓解洪水的有效途径。学者们指出,缺乏适当的信息基础和技术能力是阻碍这种整合的因素之一。这项研究发现,需要改进的是决策者个人对地理信息和地理技术的获取,而不是一个组织作为一个整体对这些资源的所有权。基于这一发现,我们设计了空间集成政策基础设施(SIPI)的目标和功能,该基础设施不仅共享地理信息,还共享模型和分析工具。还开发了SIPI的原型,以说明该SIPI的选定功能。SIPI的设计与GIS和规划领域的其他前沿研究和项目是一致的。这一发展过程也为旨在支持政策整合的基础设施的未来研究和发展提供了经验。

Breast cancer is a major health issue in all countries affecting thousands of women. Its causes are unknown and the national and international strategies to reduce its morbidity and mortality levels are based on early detection of cancer through screening and treatment according to clinical guidelines. Thus, knowledge of which women are at risk and why they are at risk is therefore essential component of disease prevention and screening. In 2015, an estimated 231,840 new cases of invasive breast cancer are expected to be diagnosed in women in the United States, along with 60,290 new cases of non-invasive (in situ) breast cancer. The purpose of this study is to provide a more detailed analysis of the breast cancer distribution in the United States by comparing the spatial distribution of breast cancer cases against physical environmental factors using Geographic Information System (GIS). Further, it gives background information to the GIS and its applications in health-related research.
乳腺癌是所有国家影响成千上万妇女的一个主要健康问题。其原因尚不清楚,降低其发病率和死亡率水平的国家和国际战略是基于根据临床准则通过筛查和治疗及早发现癌症。因此,了解哪些妇女面临风险以及她们面临风险的原因是预防和筛查疾病的重要组成部分。2015年,美国女性预计将诊断出231840例浸润性乳腺癌新病例,以及60290例非浸润性(原位)乳腺癌新病例。本研究的目的是利用地理信息系统(GIS)将美国乳腺癌病例的空间分布与自然环境因素进行比较,从而更详细地分析美国乳腺癌的分布。此外,它还提供了地理信息系统及其在健康相关研究中的应用的背景资料。

Geospatial Digital Rights Management 地理空间数字版权管理

This Chapter introduces the need for general Digital Rights Management (DRM) requirements. Further, it intertwines DRM with its spatial counterpart, Geospatial DRM (GeoDRM). However, unlike DRM, GeoDRM is far much complicated due to issues such as the development of Web Mapping technology among other issues. The Chapter discusses the ability of GeoDRM to mitigate transgression of Intellectual Property Rights (IPR). Highlighting economical and environmental wellbeing and other benefits of Spatial Data Infrastructure (SDI) geared towards global sustainable developments, the Chapter focuses on challenges of National Spatial Data Infrastructures (NSDIs) and Regional SDIs and the need to harmonize their standards for the upward mobility of global SDI (GSDI). Emphasizing the undisputed need for Local, Regional and Global Spatial Data Infrastructures (SDIs), in the presence of various Geo-communities and different GeoDRM models, the Chapter concludes that capacity building need to be urgently but carefully harnessed across all levels in order to develop cohesive GeoDRM policies.
本章介绍一般数字版权管理(DRM)要求的必要性。此外,它将DRM与空间对应的地理空间DRM (Geospatial DRM)交织在一起。然而,与DRM不同的是,由于Web Mapping技术的发展等问题,GeoDRM要复杂得多。本章讨论了地理信息管理对知识产权侵权的缓解作用。本章强调了面向全球可持续发展的空间数据基础设施(SDI)的经济和环境福祉以及其他好处,重点关注了国家空间数据基础设施(nsdi)和区域空间数据基础设施(SDI)的挑战,以及协调其标准以促进全球空间数据基础设施(GSDI)向上流动的必要性。在各种地理社区和不同的GeoDRM模型存在的情况下,本章强调了对地方、区域和全球空间数据基础设施(sdi)的无可争议的需求,并得出结论认为,为了制定有凝聚力的GeoDRM政策,需要紧急但谨慎地在各级利用能力建设。

Mermaid 美人鱼
IF 1.4 Q4 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2018-07-01 DOI: 10.4018/ijaeis.2018070103

Mermaid is a new decision support tool for managing shellfish growing areas. It is written in Visual Basic for Application (VBA) language and uses Microsoft Excel for input, calculation, and output modules. The program automatically imports the regulatory agency's data and generates scattergrams that can be used as decision support tools to help decide which shellfish growing areas should be closed and which ones should be open for harvest. The Mermaid program uses the equations developed by the Pearl model that provide more sensitive and accurate measures of sanitation safety for consumption of shellfish, and are more accurate than the U.S. National Standards.
美人鱼是管理贝类养殖区的一种新的决策支持工具。它是用VBA (Visual Basic for Application)语言编写的,使用Microsoft Excel作为输入、计算和输出模块。该程序自动导入监管机构的数据并生成散点图,这些散点图可以作为决策支持工具,帮助决定哪些贝类养殖区应该关闭,哪些应该开放捕捞。“美人鱼”项目使用由“珍珠”模型开发的方程式,为食用贝类提供了更灵敏、更准确的卫生安全措施,比美国国家标准更准确。
