A pilot mobile application enhanced by augmented reality to support participatory CoDesign in shared public spaces
Public spaces are critical urban infrastructure, shaping everyday experiences and supporting sociocultural life. Public participation has long underpinned the planning, maintenance, and redesign of these spaces, yet most digital tools remain limited to conceptual experiments based on brief engagement rather than active participatory processes with sustained feedback loops for maintenance and incremental improvement in the long-term. In this resea…

Wildfires have become increasingly frequent, irregular, and severe, contributing to diverse environmental health concerns across affected communities. Social media platforms offer an additional source of information for examining how the public discusses health risks and emotional distress during such events. This study analyzes Reddit discourse generated during the 2025 Southern California wildfires with a focus on content related to health and …
The Guide to the Geographic Approach
From mapping to GIScience
The chapter traces the evolution of geographic information science and technology over a 60-year period, from the cartography of the 1960s to the geospatial theory and services of today. This complex story is told through the contributions of two geographers: Waldo Tobler, whose career began in the 1950s with the conceptualization of what he termed analytical cartography, and the author, who was able in the 1980s to promote a vision of geographic…
Toward Ethical GeoDesign in the Urban Digital Twin Era
GeoDesign is undergoing a methodological shift through its integration with Urban Digital Twins (UDTs) and artificial intelligence (AI), moving from static spatial analysis to interactive and justice-oriented planning practices. This editorial reframes GeoDesign as both ethical and civic efforts. While digital twin technologies enable participatory planning and multiscalar data integration, they also raise concerns about bias, transparency, and g…
The Openshaw effect
Introduction
This introduction provides a brief review of the motivation, background, and context of the Forum. It explains the roles of the six papers in the Forum and the importance of reproducibility and replicability across the broad sweep of contemporary geographic research
Platial
People use two methods to specify location on the surface of the Earth: coordinates, such as latitude and longitude, and place names. The former have long been the basis for geographic information systems, as they support accurate calculations of distances and directions, and the integration of diverse types of geographic information based on shared locations. Place names are the basis for human knowledge of geography, or what is termed here plat…
Beyond Tobler’s Hiking Function
Waldo Tobler introduced his hiking function in a little‐known article in 1993, as a formal representation of the relationship between topographic gradient and the velocity of an average hiker, with parameters estimated from some previously collected data. Such functions are becoming more useful as apps for route guidance proliferate. Numerous practical issues are raised by any effort to validate these functions empirically. Hiking functions in ge…
Geography and geographic information science
GISystems have strong and longstanding roots in Geography, stemming from early developments in the 1960s and 1970s that defined a first phase of their relationship. But as the uses and sophistication of geospatial technology have grown and spread across virtually all areas of the academy, reducing Geography's claim to ownership, that relationship to Geography has evolved in new directions, forming a second phase. The critiques of the early 1990s …
Commentaries on “Evaluating the Geographic in GIS
In this article, four geographers who are also practitioners critique "Evaluating the Geographic in ." Sparked by the arguments in that article, they pose fundamental questions about how geography can best contribute to practices
Mapping Across Academia
A GIScience Perspective on the Uncertainty of Context
Geographers have long sought to understand and explain geographic phenomena through their dependence on the properties of site and situation. Yet the characterization of situation or context is fraught with numerous forms of uncertainty, related to data, the selection of situation variables, the geographic scale and extent of context, and the concept of context itself. Research into the uncertainties of geographic information has advanced substan…
Point‐of‐Interest Databases and Gazetteers
Point‐of‐interest databases and gazetteers both serve to locate named features on the Earth's surface; they differ only in the purposes for which they were constructed, and by whom. Today any distinction between them is largely irrelevant. Interest in such place‐name databases (PNDs) has been growing recently, as geographic web services aimed at the general public have proliferated. PNDs now provide support for the interface to mapping, wayfindin…

City logistics represents more than the mere transportation of goods within urban areas. It can be defined as any service provision contributing to efficiently managing the movements of goods in cities and providing innovative responses to customer demands. As such, city logistics does not apply well to the way goods are currently delivered and picked up in cities worldwide as a significant portion of these activities remains inefficient and impa…
Geographic Information Systems
Two decades on
Two meetings held in the early 1990s helped to bring about a rapprochement between the critics and proponents of GIS, and to focus research activities in what became known as critical GIScience. The motivations and conclusions of both meetings are reviewed. Since then development in GIS has been rapid, and has branched out in many new directions that call for their own assessment and critique. Six such directions are reviewed. The paper ends with…

The quality of big (geo)data
Big data is distinguished by volume, velocity, and variety. A large proportion of all big data is likely to be geographically referenced, and much may be real time. While examples can be found of high-quality big data, problems arise in meeting the normal scientific standards of replicability and rigorous sampling. These standards can be relaxed in certain stages of science, during hypothesis generation and exploration. Three methods of quality i…
Spatial, temporal, and socioeconomic patterns in the use of Twitter and Flickr
Online social networking and information sharing services have generated large volumes of spatio-temporal footprints, which are potentially a valuable source of knowledge about the physical environment and social phenomena. However, it is critical to take into consideration the uneven distribution of the data generated in social media in order to understand the nature of such data and to use them appropriately. The distribution of footprints and …

Demystifying the Persistent Ambiguity of GIS as ‘Tool’ versus ‘Science’
Is GIS a tool or a science? The question is clearly important in the day-to-day operations of geography departments. Departments need to know if GIS is a tool that should be taught at the undergraduate level, or a science and thus a legitimate research specialty of faculty and graduate students. We summarize the debate on this question that was conducted on GIS-L electronic listserver in late 1993. In evaluating this discussion it became clear th…
A Framework for the Areal Interpolation of Socioeconomic Data
Spatial data are collected and represented as attributes of spatial objects embedded in a plane. Basis change is defined as the transfer of attributes from one set of objects to another. Methods of basis change for socioeconomic data are reviewed and are seen to differ in the assumptions made in each about underlying density surfaces. These methods are extended to more general cases, and an illustration is provided by using Californian data. The …

The Validity and Usefulness of Laws in Geographic Information Science and Geography
My contribution to the session at the New Orleans meetings of the Assocation of American Geographers at which the ideas that appear in this forum were initially aired was as discussant, following the three main presentations by Barnes, Miller, and Smith. This paper expands on the comments I made during the session, and include reactions to

The Fractal Nature of Geographic Phenomena
Fractal concepts have attracted substantial popular attention in the past few years. The key ideas originated in studies of map data, and many of the applications continue to be concerned with spatial phenomena. We review the relevance of fractals to geography under three headings; the response of measure to scale, self-similarity, and the recursive subdivision of space. A fractional dimension provides a means of characterizing the effects of car…

Prospects for a Space–Time GIS
Space and time frame all aspects of the discipline of geography. Integration is normally interpreted by geographers as a straddling of the environmental–social divide, but a more profound interpretation stresses the issues involved in coupling environmental and social processes: a science of integration rather than an integration of sciences. Seven examples of distinct data types and scientific questions are examined, leading to the conclusion th…
Communicating Geographic Information in a Digital Age
ieter Brueghel the Elder painted three versions of “The Tower of Babel,” but it is the second version, painted in 1563 (Figure 1) and currently hanging in the Kunsthistorisches Museum in Vienna, that is perhaps best known. In it, Brueghel depicts events described in the eleventh chapter of the Bible’s Book of Genesis . The people conceived of a project to build a tower so high it would reach to Heaven. The style is immensely detailed, and gives a…

Specialization in the Structure and Organization of Geography
Specialty groups are a relatively recent innovation within the Association of American Geographers (AAG), but have grown rapidly to play a major part in the functioning of the organization. This paper examines the role of specialization within and between disciplines, with special reference to geography, as a response to the complexity of knowledge and of scientific activity, and as a phenomenon of social organization. The scale and basis of orga…
Space-Time Diaries and Travel Characteristics for Different Levels of Respondent Aggregation
Significant progress has been made in the analysis of space-time diary data. Drawing on the flexibility that such data provide, in this study the authors group respondents at five different levels of aggregation, and compare them according to their mean and standard deviation values for selected measures of travel behaviour. The measures, derived from the time-geography model, relate to the range and speed of daily movement and to the duration of…
Sharing Geographic Information
Humans have always exchanged geographic information, but the practice has grown exponentially in recent years with the popularization of the Internet and the Web, and with the growth of geographic information technologies. The arguments for sharing include scale economies in production and the desire to avoid duplication. The history of sharing can be viewed in a three-phase conceptual framework, from an early disorganized phase, through one cent…
Developing a curriculum in geographic information systems
We describe a major effort by the National Center for Geographic Information and Analysis (NCGIA) to develop teaching materials in support of courses in Geographic Information Systems (GIS). The project is motivated by the current high level of demand for GIS professionals and by the need to distinguish between software training on the one hand, and education in the intellectual and conceptual basis of GIS on the other. The teaching materials wer…

A tetradic analysis of GIS and society using McLuhan's law of the media
The social implications of GIS have been debated over the past five years among scholars in several disciplines. GIS have been either conceived by practitioners as value‐free, neutral tools for problem‐solving or castigated by critical social theorists as socially biased technologies serving only corporate and state interests. Neither of these polarized views is very helpful in understanding the complex relationship between GIS and society. This …

A Computerized Approach to Increased Map Library Utility
The McMaster Map Library staff, in a search for a cataloguing system for a previously uncatalogued collection of maps, is currently putting into operation an automated system for the classification and retrieval of non-topographic maps. This classification occupies a standard IBM data card of 80 columns and will produce a sorted list for any of 13 fields. Each map requires only one card where 13 cards would be required to carry the same informati…

An Evaluation of Lattice Solutions to the Problem of Corridor Location
Many route-location problems can be regarded as the minimisation of some accumulated cost, impact, or similar friction per unit length. Analogies can be found with paths of light and other least-time paths, and with geodesics. The problem is often solved by finding a path through a lattice of sample costs, with the use of modified shortest-path algorithms. Lattice paths do not converge to continuous-space paths. The differences are shown to depen…
The Spatial Structure of the Rural‐Urban Fringe
The literature contains many definitions of the rural‐urban fringe, but it is difficult to find consensus on how many zones it contains, or how they can be mapped. It is argued in this paper that transitions within the fringe and at its borders are continuous rather than abrupt. In a study area adjoining London, Ontario, cluster analysis is used, and it leads to the identification of three norms. Membership probabilities are then mapped on the ba…

The importance of urban milieu in predicting recreation participation
Numerous outdoor recreation forecasting studies have included household characteristics as well as aspects of the recreation facilities and accessibility. Only a few studies, however, have included in the prediction equation any measure of the effects of urban milieu on behavior. Four commonly cited surrogates of urban milieu are used to cluster the cities of Illinois into three relatively homogeneous groups of environments. Regression analyses a…
Randomness and Order in the Topology of Settlement Systems
"The frequency distribution of settlement links forms the basis of a linear programming methodology which can be utilized to analyze the structure of settlement systems. The resulting index of system topology is compared to a more conventional measure, Geary's contiguity coefficient, which may be applied when the problem is conceptualized as one of spatial autocorrelation on a k-color map. The index of linkage similarity that is introduced appear…

Modeling Interregional Interaction
The concept of the functional region is intimately linked to selectivity in human interaction and the ratio of within-region to between-region interaction has often been cited as a possible basis for delimiting functional regions. This paper extends the well-known spatial interaction model to the analysis of interregional and intraregional interactions. The Interregional Interaction Model explains the behavioral phenomena that we recognize as fun…
