Introduction

Geographic information systems (GIS) are the collection of software, hardware, outputs, personnel, and practices that together facilitate the analysis and mapping of geographic entities and phenomena. The field of geographic information science (GIScience) broadly explores the theory and concepts underpinning GIS and related geospatial technologies such as remote sensing and the Global Positioning System (GPS). The technological history of GIS began in the 1960s with the first rudimentary systems developed primarily for storing land information and for basic visualized outputs of geographic entities. As the technology progressed and permeated throughout the private sector, government, and academia—especially during the latter half of the 1980s and early 1990s—a growing cadre of scholars began to examine theoretical, conceptual, and intellectual questions related to the technology, in the process creating a new science of geographic information. Michael Goodchild, a geography professor at the University of California at Santa Barbara, made the first description of this area of inquiry during the 1990 Spatial Data Handling conference. Goodchild subsequently published what became an agenda-setting paper in 1992 (Goodchild 1992, cited under General Overviews) outlining a justification for this focus, which was both influential and widely accepted. GIScience draws on numerous knowledge domains, including computer science, visualization, information technology, artificial intelligence, and cognitive science to create a theoretical basis for GIS. As a relatively new field of intellectual inquiry, GIScience has developed a body of knowledge with remarkable breadth and depth. GIScientists explore diverse issues including spatial data acquisition and quality, representation and visualization; the development of database and operational standards; scale, spatial analysis/statistics, and geocomputation; and the relationship between GIS technology and society. The topic areas chosen for this article largely reflect the consensus of the GIScience academy regarding the core themes of inquiry in this field, as discussed in the General Overviews section. Further, references to current trajectories and future directions for GIScience are scattered throughout this article.

General Overviews

Goodchild 1992 set the agenda for an emerging interest in the science of geographic information. In this seminal paper, the author argues that attention should focus on the science behind GIS technology and the need to develop GIScience as an intellectual and scientific endeavor. This work describes the aspects of GIS that are “scientific,” from issues of spatial data including its collection, modeling, theories, and algorithms to spatial analysis, statistics, and analytics and managerial and ethical issues. After Goodchild’s declaration, the University Consortium for Geographic Information Science (UCGIS) was established in 1995 as a coalition of US universities, national laboratories, and learned societies. The University Consortium for Geographic Information Science 1996 documents the ten key research priorities (later to be reframed as “challenges”) for GIScience; namely, spatial data acquisition and integration, distributed computing, geographic representation, cognition, interoperability, scale, spatial analysis in GIS, spatial data infrastructures, uncertainty, and GIS and society. The 2005 UCGIS-commissioned edited book, McMaster and Usery 2005, updated and expanded on the GIScience research agenda by adding four new themes that reflected emerging priorities: geographic visualization, ontological foundations for GIScience, remotely acquired data and information, and geospatial data mining and knowledge discovery. In the years since the emergence of GIScience and the setting of its research priorities, several other key works have been written to overview the past, current state, and future of GIScience. Goodchild 1999 provides an end-of-the-millennium look at the progress of GIScience thus far—including a discussion of its acceptance, uptake, and future directions. The opening chapter in Mark 2003 provides a look at the key issues, not the least of which is the need to differentiate GIScience from scientific research that uses GIS (i.e., applied GIS), and the potential for the emergence of GIScience as a distinct discipline. The author gives an overview of the different themes proposed by UCGIS and others and provides some new ones of his own. The relationship between GISystems and GIScience—especially the need for one to inform the other—is covered in an organized manner in Gold 2006. In the first of a series of three related articles that look perhaps to the future of GIScience, Elwood 2009 examines the geospatial web (GeoWeb) and the emerging questions it poses for GIScience. Fittingly, an article reflecting on twenty years of progress in GIScience is Goodchild 2010. This article reviews the history of its emergence, its successes, and its new challenges brought on by ubiquitous positioning, citizen engagement in spatial data collection and mapping, and multidimensional GIS.
