Towards the Geographies of the 2001 UK Census of Population

A single geographical base has traditionally been created for each census of population in the United Kingdom, aimed primarily at organizing the enumeration task. The subsequent use of this enumeration geography for diverse purposes has been problematic but unavoidable. This paper examines how new digital spatial data and GIS technology are making possible the creation of separate geographies of the 2001 Census for data collection, validation, output, specification and use. The paper explores the implications of these changes for the development of a national spatial data infrastructure and for geographical research involving the census more generally.     

A GIS Atlas of the Fossil Pollen and Modern Records of Ficus and Related Species for Island South–East Asia,Australasia and the Western Pacific

Ficus has been described as a keystone genus in the tropics. This paper reviews the Quaternary palynology literature, and vegetation research literature in Island Southeast Asia, Australasia and the Western Pacific with the aim of increasing the knowledge of the distribution history for Ficus and related species within this area. Specifically, this paper describes a GIS atlas designed to aid further analysis of the history and spread of Moraceae species. This research project synthesises the knowledge of the distribution and history of Ficus and related species in the greater Australasian area through the production of a GIS atlas, and describes the project, specifically focusing on the data collation and production of the GIS.     

Remote sensing,GIS, the geospatial technologies,and Unmanned Airborne Vehicles at Aberdeen University

ABSTRACT

Aberdeen University has a long history of using aerial photography, photogrammetry, cartography, remote sensing and surveying in Geography teaching and research. The development of an MSc in Environmental Remote Sensing (ERS) in 1987 offered students a new opportunity to specialise further in this rapidly evolving area of technology. The programme has continued to thrive and the MSc in GIS celebrated its 30th Anniversary in 2017. Recently the degree has included courses on current applications of GIS and web-GIS. The introduction of UAV (Unmanned Aerial Vehicle) remote sensing broadened the appeal and competitiveness of the degree, ensuring students have access to cutting edge remote sensing technology. Alongside PhD studies, applied academic research in the Aberdeen Institute for Coastal Science and Management (AICSM), and the Unmanned Airborne Vehicle (UAV)/Unmanned Airborne System (UAS) Centre for Environmental Monitoring and Mapping (UCEMM), make widespread use of GIS and remote sensing. As the geospatial technologies continue to evolve and are integrated with drones the role of education, training and research utilising these technologies will become integral to the Geography degree. Geospatial technologies have and will continue to provide valuable tools and techniques for graduates.     

Evolving technology,shifting expectations: cultivating pedagogy for a rapidly changing GIS landscape

As humans and natural processes continuously reshape the surface of the Earth, there is an unceasing need to document and analyze them through the use of Geographic Information Systems (GIS). The public is gaining more access to spatial technologies that were once only available to highly trained professionals. With technological evolution comes a requirement to transition traditional GIS training for the next generation of GIS professionals. Traditional GIS combined with non-traditional GIS (i.e. mobile and location media) and CyberGIS educational materials could attract new and diverse students into Geography departments while informing the next generation of geospatial tool builders and users. Here we pose an applied pedagogical framework for teaching cutting-edge GIS material to diverse student populations with varying levels of technological experience and professional goals. The framework was developed as part of the National Science Foundation (NSF) CyberGIS Fellows program and was applied as a course template at the University of Washington Tacoma’s Master’s of Science in Geospatial Technologies. We chart how the framework developed into a cyclical structure from our original conceptualization as a hierarchy. This changed the epistemological orientation accommodating the shifting technological terrain of the GIS landscape to improve the skills of those driving the machines.     

Community through the eyes of children: blending child-centered research and qualitative geovisulization

Community is an ambiguous concept, and the meanings of community as a subject of study have received a great deal of attention across various disciplines. This paper discusses how children's diverse meanings of community shape and are shaped by the social, cultural, and physical environments of their everyday lives. To explore these meanings I combine principles of child-centered research and qualitative geovisualization into a research methodology. I demonstrate that this integration displays the transformative nature of qualitative analysis and visualization to support interpretive analysis of various forms of qualitative and spatial data together, and offers us a hybrid methodological framework for gaining insights into the diverse meanings of community held by the children. The main case study is drawn from a multi-year research collaboration called the Children's Urban Geography (ChUG), in which I participated along with children who lived in a relatively poor but emerging multi-cultural Hispanic neighborhood in Buffalo, NY.     

Thirty‐Four Years of Stable Isotopic Analyses of Ancient Skeletons in China: an Overview,Progress and Prospects

Stable isotope analysis of ancient skeletons has become a routine method and widely used to answer diverse archaeological questions related to the human (animal) diets since the initial study in 1977. However, this study in china is underestimated and much less unknown to international circles considering the infrequent publications in English journals. In this review paper, the research history in China was overviewed shortly and then, the research progresses concerning different research themes, such as the chronological trajectory of human diets, the development and spread of agriculture, the mechanism of animal domestication, human social hierarchy, and so on, were introduced in detail, trying to draw a rough framework of human dietary evolution given the unique Chinese geography and cultures. At last, the potential research directions were also suggested for the future studies.     

Applications of satellite remote sensing for research and heritage management in Indian prehistory

Multidisciplinary spatial studies are relatively limited in Indian archaeology, despite their potential for research and heritage management. This paper discusses applications of satellite remote sensing, field studies and GIS, in the context of Palaeolithic archaeology. The study region covers an area of around 8000 km², in the state of Tamil Nadu, South India, and is characterized by a rich and diverse Palaeolithic record. Satellite images of varied spatial resolutions were interpreted to address both regional and site-specific research questions. Thematic maps were generated from satellite data and refined with intensive field investigations. These were used for demarcating sources of raw material, and in investigating variability in the distribution of sites through time in relation to a range of geological and geomorphological features. Satellite data and field studies also aided in mapping impacts on sites resulting from modern landuse patterns. The paper also discusses the development and testing of a model to detect potential areas where new sites may be rapidly located.     

Spatial Variability of Controls on Downstream Patterns of Sediment Storage: a Case Study in the Lane Cove Catchment,New South Wales,Australia

This study uses GIS techniques to examine the spatial distribution of stream power along major streamlines in the Lane Cove catchment in northern Sydney, Australia. Channel gradient estimates derived from a 5 m resolution digital elevation model (DEM) are combined with streamflow data to estimate stream power along river courses. Stream power and its constituent components are then related to a detailed field‐based assessment of sediment storage along the trunk stream and primary tributaries. At the catchment scale, sediment storage per unit length decreases as channel gradient and gross stream power increase. However, local controls such as variability in valley width and occurrence of confluence zones exert a greater influence upon sediment storage, disrupting systematic catchment‐wide relationships. The total volume of storage along each streamline has a strong linear relationship to the area of the subcatchment, but the distribution of sediment along streamlines varies between subcatchments. The GIS framework employed in this project allows generation of continuous, empirical data, thereby providing catchment‐specific predictive capacity that can accompany theoretical approaches to stream power modelling.

我国家谱源远流长、内容丰富、数量巨大,一直是众多领域学者关注的焦点。但是,家谱研究始终处于初级阶段,家谱的价值尚未得到充分利用。其根本原因在于家谱资源分布广泛、共享困难、研究方法和手段单一。各方通力合作,利用高新技术整合现有家谱资源,建立中华家谱总数据库和总平台已迫在眉睫。本文针对家谱典型的时空特性,提出采用GIS技术整合集成海量家谱资源,并进一步探讨了家谱资源整合集成的若干关键问题,设计了家谱资源整合集成的基本原则和平台框架,为家谱研究提供了新的思路、方法和技术。     

Hidden in plain sight: mixed methods and the marble orchards of the Vlach Rom (Gypsies) in Toledo,Ohio

While American Romanies live a remarkably secretive cultural existence, their grave locations and memorial stones offer accessible evidence about their history and active, on-going communities. This article elaborates a less-intrusive ethnographic method that uses Romani cemetery data to explore and map the distributions and social networks of American Romani communities. This case study identifies Vlach Rom memorial sites located in Toledo, Ohio's Calvary Catholic Cemetery. Data were gathered on the memorials and spatially cataloged using a global positioning system (GPS). Additionally, genealogical data on the families were collected whenever available in order to construct and map family networks. Conjectures explaining the spatial distribution were tested by empirically investigating geographic information system (GIS) maps of different gravesite attributes. Land availability was the most likely factor determining the distribution. Evidence of Toledo Rom history and cultural practices were also gathered and reviewed from a qualitative analysis of the memorial stones. These discoveries have the potential to advance Romany studies—by applying modern analytic tools, GPS and GIS hardware and software to reveal otherwise “hidden” knowledge.     

Exploratory Analysis of the Homeless Shelter System in Columbus, Ohio

Abstract: A geographic information system (GIS)-based framework is structured to analyse the spatial characteristics and patterns associated with a system of homeless shelters and services. Given the lack of detailed spatial information available to decision-makers and shelter operators, the siting of new shelters and services is often carried out with little supporting information. The shelter system in Columbus, Ohio is investigated. Personal interviews with shelter providers and local decision-makers offers a look at their collective understanding of the services needed by Columbus' homeless population and the spatial patterns and socio-economic characteristics that define the neighbourhoods in which shelters are located. The use of GIS facilitates an exploratory data analysis that allows these understandings to be examined, affording planners and decision-makers the opportunity to move beyond perceptions of the system. Findings indicate that while many perceptions are supported empirically, there are perceptions that are not substantiated. This research provides a basis for the evaluation of important social services in an urban area where perception influences planning and decision-making.     

基于GIS的沈阳旧城区叙事空间研究

20世纪60年代,叙事学作为一门学科始于西方历史学、文学领域。直至20世纪末,叙事学开始转向空间领域研究形成空间叙事学,并被逐步应用到城乡规划中,尤其是城乡空间结构等领域。空间叙事学不仅关注城市发展中的物化要素,更加注重物化要素所代表的城市文化和城市记忆等非物化要素的深入挖掘,是探究场所本体与场所精神的重要研究思路。本文从空间叙事学出发,基于GIS平台运用核密度及K函数对古代、近代、现代三个时期沈阳旧城区人工叙事要素和人文事件叙事要素进行点模式量化分析,得出沈阳旧城区叙事空间的总体结构,以及叙事点核、叙事廊道、叙事簇群等叙事空间结构单元,指出沈阳旧城区叙事空间的动态发展性、功能多样性和历史传承性特点,探讨了叙事空间的经济驱动、自然要素、城市定位和交通发展四大演变机制。从人文地理学的视角出发,结合叙事空间理论对沈阳旧城区叙事空间进行分析,结果具有文化地理和城市地理双重属性,丰富了城市研究在该视角下的研究成果。     

Experiencing Ancient Buildings from a 3D GIS Perspective: a Case Drawn from the Swedish Pompeii Project

In recent times, archaeological documentation strategies have been considerably improved by the use of advanced 3D acquisition systems. Laser scanning, photogrammetry and computer vision techniques provide archaeologists with new opportunities to investigate and document the archaeological record. In spite of this, the amount of data collected and the geometrical complexity of the models resulting from such acquisition processes have always prevented their systematic integration into a geographic information systems (GIS) environment. Recent technological advances occurred in the visualization of 3D contents, led us to overcome the aforementioned limitations and set up a work pipeline in which was possible to put the 3D models not only in the context of data visualization but also in the frame of spatial analysis. The case study described is a part of the Swedish Pompeii Project, a research and fieldwork activity started in 2000 with the purpose of recording and investigating an entire Pompeian city block, Insula V 1. As an additional part of the research, a laser scanning acquisition campaign was conducted in the last few years. The resulting models were thus meant to be used to develop further research lines: Among these, a 3D GIS system was expected to be set up with the purpose to (i) collect in the same geo-referenced environment, different typologies of documentation gathered in the context of the Swedish Pompeii Project; (ii) inter-connect 3D models with the project website; (iii) use the third dimension as a further analytical field of investigation, in the form of spatial analysis and cognitive simulation.     

The SpatialARMED Framework: Handling Complex Spatial Components in Spatial Association Rule Mining

Recent research has identified spatial association rule (SAR) mining as a promising technique for geographic pattern mining and knowledge discovery. Nevertheless, important spatial components embedded in the studied phenomenon, in particular complex spatial functional relations such as neighborhood effects and spatial spillover effects have largely been neglected. This article unravels this specific problem to enhance the effective application of SAR mining practices in spatial data analytics. The main discussion focuses on the specification of complex spatial components by means of spatial dependence properties of the data and on how to integrate them in the process of SAR mining. A comprehensive framework dubbed SpatialARMED is proposed for the effective extraction of spatial patterns. The framework is then showcased through its application to crime analysis.     

世界历史教学的挑战

当今,无论在研究领域还是教学领域,世界历史都成为最重要的议题之一。人们可以真切地感受到有关世界体系的历史研究取得了长足发展。这一新趋势削弱了传统的中、小学历史教学,传统历史教学建立在种族中心主义方法基础之上,被民族国家用于加强民族集体认同（通常与其他国家相对立）。与此相反,新的世界历史教学可以被视为一种开展不同文化间教育和加强世界主义的手段。这里建议世界历史课程计划以概念、空间和时间这三重框架为基础。概念框架集中于两个主题：人类社会的演进及其相互交往;空间框架可以持续利用与主题有关的球体投影图来展示;时间框架由基于9个时代的历史分期连接起来,另附一个时期论述未来前景。     

Vico and the disgregation of historia salutis

This study aims to analyse the problem of Vico’s religiosity, still a subject for debate, in the European tradition of universal historiography. Vico’s historical reconstruction has traditionally been considered as orthodox and apologetic. The Neapolitan philosopher, in his major work, New Science, tried to defend not only the historical veracity and authority of biblical narratives as the only source to reconstruct the initial phases of history, but also the temporal and spatial frame of historia salutis, confuting the thesis of a greater antiquity of pagan nations. Nonetheless, it is difficult to conclude that Vico’s historical reconstruction followed the same route of the apologists of his time. Vico demolished not the temporal and spatial sphere, but the unitary frame of historia salutis. In Vico’s setting, all nations formed their civilizations in an autochthonous way and developed them autonomously with diverse timetables. Vico introduced the concept of the plurality of history. In this way, the Neapolitan philosopher contributed to the process of secularization of universal history in a completely different way from his contemporaries.     

Potential Contributions of Spatial Analysis to Geographic Information Systems for Transportation (GIS-T)

Geographic information systems (GIS) are having tremendous impacts on many scientific and application domains. The traditional subfield of spatial analysis is witnessing a major resurgence and enhancement due to GIS and geographical information science (GISci), an interdisciplinary field focusing on the theory and methodology underlying GIS software. The interdisciplinary field of geographic information systems for transportation (GIS-T) has emerged to focus on the role of GIS in transportaton analysis and planning. This paper suggests the benefits of closer linkages between spatial analysis, GISci, and transportation through a focused review of spatial analytical issues and their potential contributions to GIS-T. Specifically, this paper reviews the following issues: (i) modifiable areal units; (ii) boundary problems and spatial sampling; (iii) spatial dependence and spatial heterogeneity; and (iv) alternative representations of geographic environments. The discussion highlights the general issues as well as identifies their specific relevance to GIS-T. In addition, this paper identifies some emerging tools from GISci that can address these spatial analytical issues in GIS-T.     

Spatial/temporal mismatch: a conflation protocol for Canada Census spatial files

The Canada census is one of the chief sources of demographic and socio-economic data for researchers in this country. Census variables are linked to geography files that allow researchers using geographic information systems (GIS) to view and analyze spatial data. Some of the most useful analysis, however, is based on changes in attribute values over time and space. Analysis of spatio- temporal events such as shifting migration patterns or changes in the distribution of health status permits a more dimensioned perspective than the viewing of static spatial phenomena. The analysis of spatio-temporal phenomena is limited by major changes in the spatial framework (e.g., location of road networks and other spatial entities) between national censuses. This paper addresses this limitation by (i) illustrating the extent of spatial mismatch between the 1996 and the 2001 census; (ii) examining attempts to rectify this problem in other jurisdictions and (iii) presenting a 'made-in-Canada' solution for conflation of census geometries. We believe that this solution will enhance the ability of Canadian researchers to describe and analyze socio-economic, health and demographic shifts across time and space.
