William Louis Garrison (1924–2015) was an American geographer, transportation analyst and professor at the University of California, Berkeley. While at the Department of Geography, University of Washington in the 1950s, Garrison led the "quantitative revolution" in geography, which applied computers and statistics to the study of spatial problems. As such, he was one of the founders of regional science. Many of his students went on to become noted professors themselves, including: Brian Berry, Ronald Boyce, Duane Marble, Richard Morrill, John Nystuen, William Bunge, Michael Dacey, Arthur Getis, and Waldo Tobler. His transportation work focused on innovation, the deployment of modes and logistic curves, alternative vehicles and the future of the car.
The First Law of Geography, according to Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." This first law is the foundation of the fundamental concepts of spatial dependence and spatial autocorrelation and is utilized specifically for the inverse distance weighting method for spatial interpolation and to support the regionalized variable theory for kriging. The first law of geography is the fundamental assumption used in all spatial analysis.
The quantitative revolution (QR) was a paradigm shift that sought to develop a more rigorous and systematic methodology for the discipline of geography. It came as a response to the inadequacy of regional geography to explain general spatial dynamics. The main claim for the quantitative revolution is that it led to a shift from a descriptive (idiographic) geography to an empirical law-making (nomothetic) geography. The quantitative revolution occurred during the 1950s and 1960s and marked a rapid change in the method behind geographical research, from regional geography into a spatial science.
Geography is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines."
Quantitative geography is a subfield and methodological approach to geography that develops, tests, and uses scientific, mathematical, and statistical methods to analyze and model geographic phenomena and patterns. It aims to explain and predict the distribution and dynamics of human and physical geography through the collection and analysis of quantifiable data. The approach quantitative geographers take is generally in line with the scientific method, where a falsifiable hypothesis is generated, and then tested through observational studies. This has received criticism, and in recent years, quantitative geography has moved to include systematic model creation and understanding the limits of their models. This approach is used to study a wide range of topics, including population demographics, urbanization, environmental patterns, and the spatial distribution of economic activity. The methods of quantitative geography are often contrasted by those employed by qualitative geography, which is more focused on observing and recording characteristics of geographic place. However, there is increasing interest in using combinations of both qualitative and quantitative methods through mixed-methods research to better understand and contextualize geographic phenomena.
Cynthia Ann Brewer is an American cartographer, author, and professor of geography at Pennsylvania State University. Brewer's specialty relates to visibility and color theory in cartography and, in 2023, she was awarded the International Cartographic Society's highest honor, the Carl Mannerfelt Gold Medal, for her distinguished contribution to the field.
The Department of Geography at the University of Washington is a key site for the contemporary development of critical geography and was a significant location for the quantitative revolution. The department is located in Seattle, Washington and has been highly ranked among leading geography graduate programs in the United States.
Mei-Po Kwan is a Hong Kong geographer and academic. Her contributions to the field include environmental health, human mobility, transport and health issues in cities, and geographic information science (GIScience).
Michael N. DeMers is a geographer and professor emeritus of geography at New Mexico State University.
Technical geography is the branch of geography that involves using, studying, and creating tools to obtain, analyze, interpret, understand, and communicate spatial information.
George Frederick Jenks (1916–1996) was an American geographer known for his significant contributions to cartography and geographic information systems (GIS). With a career spanning over three decades, Jenks played a vital role in advancing map-making technologies, was instrumental in enhancing the visualization of spatial data, and played foundational roles in developing modern cartographic curricula. The Jenks natural breaks optimization, based on his work, is still widely used in the creation of thematic maps, such as choropleth maps.
Arthur Getis was an American geographer known for his significant contributions to spatial statistics and geographic information science (GIScience). With a career spanning over four decades, Getis authored more than one hundred peer-reviewed papers and book chapters, greatly influencing GIScience and geography as a whole. The Getis-Ord family of statistics, one of the most commonly used in spatial analysis, is based on his and J. Keith Ord's work and is still widely used in the creation of hot spot maps.
Alexander Stewart Fotheringham is a British-American geographer known for his contributions to quantitative geography and geographic information science (GIScience). He holds a Ph.D. in geography from McMaster University and is a Regents professor of computational spatial science in the School of Geographical Sciences and Urban Planning at Arizona State University. He has contributed to the literature surrounding spatial analysis and spatial statistics, particularly in the development of geographically weighted regression (GWR) and multiscale geographically weighted regression (MGWR).
Duane Francis Marble was an American geographer known for his significant contributions to quantitative geography and geographic information science (GIScience). Marble had a 40-year career as a professor at multiple institutions, retiring from the Ohio State University and holding a courtesy appointment as Professor of Geosciences at Oregon State University afterward. His early work was highly influential in computer cartography and is regarded as a significant contributor to the quantitative revolution in geography. His work on constructing a "Model Curricula" in GIScience is listed as the starting foundation built upon by the Geographic Information Science and Technology Body of Knowledge.
Rebecca Lave is a geographer, professor of geography at Indiana University Bloomington (IU), and the current president of the American Association of Geographers (AAG). Her research focuses on critical geography, as it applies to physical geography, as part of the emerging field of critical physical geography. She has focused on bridging the gap between physical and human geography in her research, as a department chair at IU, and as the president of the AAG.
Michael Francis Dacey was an American geographer known for his significant contributions to mathematical models in quantitative geography. Dacey founded the department of Mathematical Methods in the Social Sciences at Northwestern University, where he served as a senior associate dean in the College of Arts and Science, as well as a professor of geography, anthropology, and geological sciences. His publications were instrumental in establishing quantitative geography in mainstream geography.
Waldo Tobler's publications span between 1957 and 2017, with his most productive year being 1973. Despite retirement in 1994, he continued to be involved with research for the remainder of his life. Most of his publications consist of peer-reviewed journals, without single-issue textbooks or monographs, and the quantity of publications is noted as being unremarkable compared to modern geographers. Many of his works are foundational to modern geography and cartography, and still frequently cited in modern publications, including the first paper on using computers in cartography, the establishment of analytical cartography, and coining Tobler's first and second laws of geography. His work covered a wide range of topics, with many of his papers considered to be "cartographic classics", that serve as required reading for both graduate and undergraduate students.
