“Power to the people”: Contesting urban poverty and power inequities through open GIS

Geospatial technologies are central to spatial decision making and governance, but gaining equitable access to these is still difficult for traditionally marginalized communities. We contend that the dominance of proprietary GIS software has contributed to this digital divide, as these are inherently disempowering to marginalized social groups. Their high purchasing cost and licensing fees pose access barriers to resource‐poor citizens. Design of proprietary software may also not be appropriate for marginalized groups who are neither trained in GIS, nor represent the needs of dominant market base. Therefore, “free and open source software for geospatial” (FOSS4G) and open GIS provide new opportunities in democratizing GIS, as these are open code and free of purchasing and licensing costs. This paper aims to discuss the role of open GIS in advancing the goals of public participation GIS (PPGIS). We first discuss the origins of the FOSS movement, and explore the ways it has shaped the FOSS4G and open GIS movements. Next, we examine how a community information system built with open GIS software is being successfully utilized by an environmental organization in Milwaukee, to contest urban poverty. Our research demonstrates that open source GIS offers unique opportunities in advancing PPGIS research and practice.     

Teaching critical open GIS

Higher-education geographic information system (GIS) curricula largely marginalize and separate instruction of critical GIS and open GIS, paralleling a divide between GIS and non-GIS in geography. GIS is typically represented as a singular, infallibly objective, and universally applicable technology. GIS generally dismisses the critiques from human geography, while critical human geography dismisses GIS for its association with positivism and unethical applications. Teaching critical open GIS may bridge this divide, creating a transformative pedagogical space for human geography to affectively and effectively engage with open GIS technology at the level of code. Critical open GIS students practice and critique GIS as conflicted insiders, bridging the divide between GIS and non-GIS in their geography education. Reviews of GIS curricula find support for teaching critical and open GIS, but reviews of texts and syllabi confirm their marginalization and separation. A new critical open GIS course is introduced, using GIS in development and political ecology as integrative frameworks.     

Teaching creative geovisualization: Imagining the creative in/of GIS

Creative geovisualization is situated at the intersection of geography, arts, and digital humanities with a particular emphasis on visualization and mapping that preserves, represents, and generates more authentic, contextual, and nuanced meanings of space and people with an artistic and humanistic perspective and approach. This is a creative expansion in critical GIS practices and a new alternative to traditionally science-rooted approaches to GIS and mapping. Reflecting the experience of teaching a “creative geovisualization” course in an interdisciplinary curriculum, I demonstrate how critical and creative scholarship with mapping and geovisualization is introduced in the classroom and is illuminated in the students' creative practices. The class encompasses key epistemological and methodological groundings of creative geovisualization—including non-representational theories; critical cartography and GIS; the convergence of geography, arts, and humanities; psychogeography; and qualitative and affective geovisualization. Empirical examples of students' works illustrate the blending of different modes of creative engagements with GIS and geovisualization and specific ways to work with various forms of embodied, relational, interpretive, and expressive geographies. GIS and mapping become creative as they continue evolving in process, and it is time that we deeply (re-)imagine “the creative” in/of GIS in critical GIS pedagogies.     

Reimagining GIScience for relational spaces

A mismatch between largely absolute Newtonian models of space in GIScience and the relational spaces of critical human geography has contributed to mutual disinterest between the fields. Critical GIS has offered an intellectual critique of GIScience without substantially altering how particular key geographical concepts are expressed in data structures. Although keystone ideas in GIScience such as Tobler's “First Law” and the modifiable areal unit problem speak to enduring concerns of human geography, they have drawn little interest from that field. Here, we suggest one way to reformulate the computational approach to the region for relational space, so that regions emerge not through proximity in an absolute space or similarities in intensive properties, but according to their similarities in relations. We show how this might operate theoretically and empirically, working through three illustrative examples. Our approach gestures toward reformulating key terms in GIScience like distance, proximity, networks, and spatial building blocks such as the polygon. Re‐engaging the challenges of representing geographical concepts computationally can yield new kinds of GIS and GIScience resonant with theoretical ideas in human geography, and also lead to critical human geographic practices less antagonistic to computation.     

The poverty of GIS theory: Continuing the debates around the political economy of GISystems

Over the past several decades, GISystems and GIScience have become established and valorized within the field of geography and geographic education. With the recent explosion in daily use of devices producing spatial data, such as smartphones, has come a renewed call to broaden the purview of Critical GIS beyond the desktop and towards these new systems of capitalist accumulation. In this viewpoint, we argue that any re‐examination of the role of Critical GIS must also consider the political economy of geography and geographic education in which GISystems are used for research and taught. We explicate three registers at which GISystems function within geography: that of the individual educator, that of the GIS user, and that of the military‐industrial complex in which GISystems were and are developed.     

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.     

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.     

Perspectives and sensitivities: teaching as the creation of conditions of possibility for geographic thinking

Abstract

Teaching methodological courses means providing students with general ideas to think with, rather than specific facts to think about. Rethinking the teaching task must be informed by an awareness of ideological, philosophical, technical and analytical perspectives, and should look for basic themes uniting apparently different approaches. Almost all quantitative methodologies are actually specific examples of the mathematical operation of mapping. Genuine understanding is achieved by visualisation of a problem, rather than algebraic manipulation, and the teaching task could be aided greatly by employing the power of interactive computer graphics. It is suggested that the analytical and pedagogic approaches used by experienced teachers might be shared initially in an international conference, and so form the basis for more effective and efficient teaching in the future.     

Cyborg geographies: towards hybrid epistemologies

As a mode of critique, the cyborg is often separated from its role as a figuration. This article reviews Donna Haraway's cyborg theory to restate the importance of the cyborg as a figuration in critical methodology. Figuration is about opening knowledge-making practices to interrogation. I argue that the cyborg enables this inquiry through epistemological hybridization. To do so, cyborg figurations not only adopt a language of being or becoming, but narrate this language in the production of knowledges, to know hybridly. The epistemological hybridization of the cyborg includes four strategies: witnessing, situating, diffracting and acquiring. These are modes of knowing in cyborg geographies. To underline the importance of this use of cyborg theory, I review selected geographic literatures in naturecultures and technosciences, to demonstrate how geographers cite the cyborg. My analysis suggests these literatures emphasize an ontological hybridity that leaves underconsidered the epistemological hybridization at work in cyborg figuration. To take up the cyborg in this way is to place at risk our narrations, to re-make these geographies as hybrid, political work.     

The future role of GIS education in creating critical spatial thinkers

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.     

COVID-19 in Chihuahua,Mexico: Assessing its spatial behaviour through the inverse distance weighted interpolation technique

This study focused on the spatial evolution of COVID-19 in the state of Chihuahua, Mexico. Data were retrieved from governmental databases and analyzed by means of GIS, applying the inverse distance weighted (IDW) method. The period of December 2019 through November 2021 was split into eight seasons. The root mean square error (RMSE) was used to assess the reliability of the interpolations, showing acceptable values (RSME < 25). During the period, the municipalities of Juarez and Chihuahua reached the highest number of confirmed cases and deaths, Juarez being the main hotspot of contagion (37.2% of confirmed cases; 46.9% of deaths). Four waves of contagion were identified during the evaluated period, with Fall 2020 being the strongest season. Since Fall 2020, the spread of the disease was more often observed in municipalities with the highest human mobility. Although the spread of COVID-19 decreased after Spring 2021, in Fall 2021 records indicated a continuous increase in cases in the state. That could be due to a relaxation of the implementation of sanitary measures, as well as to the propagation of novel COVID-19 variants having an elevated infectious level. Geospatial techniques allowed for an understanding of the spatial spread of COVID-19 and could be useful for its control.     

Operating anew: Queering GIS with good enough software

In the last decade, conversations around queering of GIScience emerged. Drawing on literature from feminist and queer critical GIS, with special attention to the under‐examined political economy of GIS, I suggest that the critical project of queering all of GIS, both GIScience and GISystems, requires not just recognition of the labour and lives of queers and research in geographies of sexualities. Based upon a queer feminist political economic critique and evidenced in my teaching critical GIS at two elite liberal arts colleges, I argue that the “status quo” between ESRI and geography as a field must be interrupted. Extending a critical GIS focus beyond data structures and data ethics, I argue that geographic researchers and instructors have a responsibility in queering our choice and production of software, algorithms, and code alike. I call this production and choice of democratic, accessible, and useful software by, for, and about the needs of its users, good enough software.     

GIS Methods in Time-Geographic Research: Geocomputation and Geovisualization of Human Activity Patterns

Over the past 40 years or so, human activities and movements in space‐time have attracted considerable research interest in geography. One of the earliest analytical perspectives for the analysis of human activity patterns and movements in space‐time is time geography. Despite the usefulness of time geography in many areas of geographical research, there are very few studies that actually implemented its constructs as analytical methods up to the mid‐1990s. With increasing availability of geo‐referenced individual‐level data and improvement in the geo‐computational capabilities of Geographical Information Systems (GIS), it is now more feasible than ever before to operationalize and implement time‐geographic constructs. This paper discusses recent applications of GIS‐based geo‐computation and three‐dimensional (3‐D) geo‐visualization methods in time‐geographic research. The usefulness of these methods is illustrated through examples drawn from the author's recent studies. The paper attempts to show that GIS provides an effective environment for implementing time‐geographic constructs and for the future development of operational methods in time‐geographic research.     

Facilitating spatial thinking in world geography using Web-based GIS

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.     

Development of critical spatial thinking through GIS learning

This study developed an interview-based critical spatial thinking oral test and used the test to investigate the effects of Geographic Information System (GIS) learning on three components of critical spatial thinking: evaluating data reliability, exercising spatial reasoning, and assessing problem-solving validity. Thirty-two students at a large state university completed pre- and post-tests administered during the 2010 fall semester. This study found positive relationships between GIS learning and critical spatial thinking. We argue that the improvement can be attributed to students' experiences in a GIS course.     

Lost in Translation: Cross-Cultural Experiences in Teaching Geo-Genealogy

This paper reports on a cross-cultural outreach activity of the current UK ‘Spatial Literacy in Teaching’ (SPLINT) Centre of Excellence in Teaching and Learning (CETL), a past UK Economic and Social Research Council (ESRC) grant, and shared interests in family names between Japanese and UK academics. It describes a pedagogic programme developed for Japanese postgraduates and advanced undergraduates that entailed quantitative and qualitative analysis of the spatial distributions of Japanese family names. The authors describe some specific semantic, procedural and theoretical issues and, more generally, suggest how names analysis provides a common framework for engaging student interest in GIS.     

Testing settlement models in the early Roman colonial landscapes of Venusia (291 B.C.), Cosa (273 B.C.) and Aesernia (263 B.C.)

This paper examines settlement density and settlement patterns in the Roman colonial territories of Venusia, Cosa and Aesernia, located in three different landscapes of central southern Italy (modern Basilicata, Tuscany and Molise). Using a series of GIS tools, we conducted a comparative analysis of the density and spatial distribution of sites dating to the Hellenistic period (ca. 350–50 b.c.). We used the legacy settlement data collected by previous large-scale, intensive, site-oriented field surveys to test the validity of two competing rural settlement models of early Roman colonization: the conventional model of neatly organized settlements regularly dispersed across the landscape and the recently proposed theory that colonists adopted a polynuclear settlement strategy. After calculating the extent to which the archaeological datasets conform to the regular or polynuclear model, we conclude that only a very small portion of the colonized areas actually meets traditional expectations regarding the organization of early colonial settlements. Our analyses show that the legacy survey data is more consistent with the polynuclear settlement theory, but the data also reveals some completely unexpected patterns, suggesting that early Roman colonial landscapes were more diverse than previously thought.     

Multidisciplinary Cooperation in GIS Education: A Case Study of US Colleges and Universities

This paper examines the degree of multidisplinary cooperation for Geographic Information Science (GIS) education programs that award GIS-related degrees or certificates at US colleges and universities. We classified departments and courses into ten major disciplines using Dewey Decimal Classification. In the 2007–2008 academic year, approximately 40 per cent of GIS education programs related to multiple disciplines and nearly 20 per cent were involved with more than three disciplines. Geography was the major provider of GIS education programs, but the ratio between geography-related discipline and other disciplines combined was approximately 1:3. Fostering multidisciplinary GIS education programs should strengthen geography in general as well as GIS education.     

Our GIS is too small

GIScience and GISystems have been successful in tackling many geographical problems over the last 30 years. But technologies and associated theory can become limiting if they end up defining how we see the world and what we believe are worthy and tractable research problems. This paper explores some of the limitations currently impacting GISystems and GIScience from the perspective of technology and community, contrasting GIScience with other informatics communities and their practices. It explores several themes: (i) GIScience and the informatics revolution; (ii) the lack of a community‐owned innovation platform for GIScience research; (iii) the computational limitations imposed by desktop computing and the inability to scale up analysis; (iv) the continued failure to support the temporal dimension, and especially dynamic processes and models with feedbacks; (v) the challenge of embracing a wider and more heterogeneous view of geographical representation and analysis; and (vi) the urgent need to foster an active software development community to redress some of these shortcomings. A brief discussion then summarizes the issues and suggests that GIScience needs to work harder as a community to become more relevant to the broader geographic field and meet a bigger set of representation, analysis, and modelling needs.
