Leveraging the Science of Geographic Information Systems

The Center for Geographic Information Science (CGISc) at the University of North Carolina Greensboro (UNCG) was established in the Summer of 2006. CGISc is an educational research entity that relies on the use of GIS and the science of geographic information to conduct research on human and natural phenomena distributed on the Earth’s surface. CGISc welcomes interdisciplinary collaboration, and emphasizes the development of public-private sector partnerships. CGISc also places a high priority on research that involves students. This paper first provides an overview of the CGISc. This section is followed by a discussion on the fundamental approach to conducting geographic research using GIS. The paper concludes with several significant projects and a discussion on future directions

A new decade of uses for geographic information systems (GIS) as a tool to research, measure and analyze library services

Purpose: The purpose of this paper is to explore library research that uses geographic information systems (GIS) as a tool to evaluate library services and resources to ascertain current trends and establish future directions for this growing research area. Design/Methodology/Approach: The study searched full text for geographic information systems in two databases: Library and Information Science Source (LISS) and Library, Information Science and Technology Abstracts (LISTA), replicating the method used in a prior literature review. The titles and abstracts of the search results were analyzed to gather only the research that used GIS as a tool to measure and analyze library services. Findings: This study found growth in the last decade for library research using GIS. There remain two ways the tool is primarily used: to analyze service areas and to manage facilities and collections. Practical Implications: The findings are relevant for library and information science researchers and practitioners because they summarize a specific area of research that has grown and changed and that still has potential to be used more widely. Using GIS in practice and research could benefit all library users and nonusers because spatial analysis facilitates more precise and informed delivery of services and resources. Originality/Value: The paper provides future directions for use of GIS in library research and attempts to define subdivisions within this research area to clarify the area for researchers and practitioners

Citizen Science and Geospatial Capacity Building

This book is a collection of the articles published the Special Issue of ISPRS International Journal of Geo-Information on “Citizen Science and Geospatial Capacity Building”. The articles cover a wide range of topics regarding the applications of citizen science from a geospatial technology perspective. Several applications show the importance of Citizen Science (CitSci) and volunteered geographic information (VGI) in various stages of geodata collection, processing, analysis and visualization; and for demonstrating the capabilities, which are covered in the book. Particular emphasis is given to various problems encountered in the CitSci and VGI projects with a geospatial aspect, such as platform, tool and interface design, ontology development, spatial analysis and data quality assessment. The book also points out the needs and future research directions in these subjects, such as; (a) data quality issues especially in the light of big data; (b) ontology studies for geospatial data suited for diverse user backgrounds, data integration, and sharing; (c) development of machine learning and artificial intelligence based online tools for pattern recognition and object identification using existing repositories of CitSci and VGI projects; and (d) open science and open data practices for increasing the efficiency, decreasing the redundancy, and acknowledgement of all stakeholders

A Survey of Modelling Trends in Temporal GIS

The main achievements of spatio-temporal modelling in the field of Geographic Information Science that spans over the past three decades are surveyed. This article offers an overview of: (i) the origins and history of Temporal Geographic Information Systems (T-GIS); (ii) relevant spatio-temporal data models proposed; (iii) the evolution of spatio-temporal modelling trends; and (iv) an analysis of the future trends and developments in T-GIS. It also presents some current theories and concepts that have emerged from the research performed, as well as a summary of the current progress and the upcoming challenges and potential research directions for T-GIS. One relevant result of this survey is the proposed taxonomy of spatio-temporal modelling trends, which classifies 186 modelling proposals surveyed from more than 1450 article

Assessing the current and future potential geographic distribution of the American dog tick, Dermacentor variabilis (Say) (Acari: Ixodidae) in North America

The American dog tick, Dermacentor variabilis, is a veterinary- and medically- significant tick species that is known to transmit several diseases to animal and human hosts. The spatial distribution of this species in North America is not well understood, however; and knowledge of likely changes to its future geographic distribution owing to ongoing climate change is needed for proper public health planning and messaging. Two recent studies have evaluated these topics for D. variabilis; however, less-rigorous modeling approaches in those studies may have led to erroneous predictions. We evaluated the present and future distribution of this species using a correlative maximum entropy approach, using publicly available occurrence information. Future potential distributions were predicted under two representative concentration pathway (RCP) scenarios; RCP 4.5 for low-emissions and RCP 8.5 for high-emissions. Our results indicated a broader current distribution of this species in all directions relative to its currently known extent, and dramatic potential for westward and northward expansion of suitable areas under both climate change scenarios. Implications for disease ecology and public health are discussed.PHS grant number AI070908National Institutes of Allergy and Infectious DiseaseIIA-1920946National Science Foundatio

Geographic distributions of psychological characteristics across diverse social and physical environments

Over the past decade, interest in geographical approaches to psychology has flourished and a large literature has accumulated. The emerging perspective of geographical psychology is an interdisciplinary approach to human activity that focuses on the spatial organization of psychological experiences (e.g., Rentfrow, 2010, 2014; Rentfrow, Gosling, & Potter, 2008; Rentfrow & Markus, 2016). In recent years, this view has successfully integrated research across epidemiology, political science, urban design, economics, and geography by promoting the tradition of studying behaviour in the context of physical space. In a broad sense, the goal of this thesis is to provide additional evidence of the benefits of exploring psychological phenomena using a geographical perspective. Two streams of information provide support for this position: (1) a review of the relevant literature in geographical, evolutionary, and personality psychology; (2) six peer-reviewed published studies, all co-authored by the current author, that address individual differences in personality, attachment, and romantic behaviour across cultural and geographic regions. The total composition is divided into four major sections that provide a detailed overview of geographical, evolutionary, and personality psychology before presenting prior publications and future research directions. Part I introduces the rationale for the dissertation and includes a critical review of research on geographic distributions of psychological variables. Part II covers evolutionary and personality approaches and presents three empirical studies dealing with personality patterns and romantic attachment. Part III contains a chapter on emotions in romantic relationships and three cross cultural prior publications. The work concludes with a general discussion in Part IV wherein a general model, future research directions, and limitations are considered

Voronoi-Based Region Approximation for Geographical Information Retrieval with Gazetteers

Gazetteers and geographical thesauri can be regarded as parsimonious spatial models that associate geographical location with place names and encode some semantic relations between the names. They are of particular value in processing information retrieval requests in which the user employs place names to specify geographical context. Typically the geometric locational data in a gazetteer are confined to a simple footprint in the form of a centroid or a minimum bounding rectangle, both of which can be used to link to a map but are of limited value in determining spatial relationships. Here we describe a Voronoi diagram method for generating approximate regional extents from sets of centroids that are respectively inside and external to a region. The resulting approximations provide measures of areal extent and can be used to assist in answering geographical queries by evaluating spatial relationships such as distance, direction and common boundary length. Preliminary experimental evaluations of the method have been performed in the context of a semantic modelling system that combines the centroid data with hierarchical and adjacency relations between the associated place names

Technology Integration around the Geographic Information: A State of the Art

One of the elements that have popularized and facilitated the use of geographical information on a variety of computational applications has been the use of Web maps; this has opened new research challenges on different subjects, from locating places and people, the study of social behavior or the analyzing of the hidden structures of the terms used in a natural language query used for locating a place. However, the use of geographic information under technological features is not new, instead it has been part of a development and technological integration process. This paper presents a state of the art review about the application of geographic information under different approaches: its use on location based services, the collaborative user participation on it, its contextual-awareness, its use in the Semantic Web and the challenges of its use in natural languge queries. Finally, a prototype that integrates most of these areas is presented
