GeoDa : An Introduction to Spatial Data Analysis Luc Anselin 1 , Ibnu Syabri 2 , Youngihn Kho 1 1 Spatial Analysis Laboratory, Department of Geography, University of Illinois, Urbana, IL, 2 Laboratory for Spatial Computing and Analysis, Department of Regional and City Planning, Institut Teknologi, Bandung, Indonesia This article presents an overview of GeoDa TM , a free software program intended to serve as a user-friendly and graphical introduction to spatial analysis for non- geographic information systems (GIS) specialists. It includes functionality ranging from simple mapping to exploratory data analysis, the visualization of global and local spatial autocorrelation, and spatial regression. A key feature of GeoDa is an interactive environment that combines maps with statistical graphics, using the technology of dynamically linked windows. A brief review of the software design is given, as well as some illustrative examples that highlight distinctive features of the program in applications dealing with public health, economic development, real estate analysis, and criminology. Introduction The development of specialized software for spatial data analysis has seen rapid growth as the lack of such tools was lamented in the late 1980s by Haining (1989) and cited as a major impediment to the adoption and use of spatial statistics by geographic information systems (GIS) researchers. Initially, attention tended to focus on conceptual issues, such as how to integrate spatial statistical methods and a GIS environment (loosely versus tightly coupled, embedded versus modular, etc.), and which techniques would be most fruitfully included in such a framework. Familiar reviews of these issues are represented in, among others, Anselin and Getis (1992); Goodchild et al. (1992); Fischer and Nijkamp (1993); Fotheringham and Rogerson (1993, 1994); Fischer, Scholten, and Unwin (1996); and Fischer and Getis (1997). Today, the situation is quite different, and a fairly substantial collection of spatial data analysis software is readily available, ranging from niche programs, customized scripts and extensions for commercial statistical and GIS packages, to a Correspondence: Luc Anselin, Department of Geography, University of Illinois, Urbana- Champaign, Urbana, IL 61801 e-mail: [email protected] Submitted: January 1, 2004.

burgeoning open-source effort using software environments such as R, Java, and Python. This is exemplified by the growing contents of the software tools clearing house maintained by the U.S.-based Center for Spatially Integrated Social Science (CSISS). 1 CSISS was established in 1999 as a research infrastructure project funded by the U.S. National Science Foundation in order to promote a spatial analytical perspec- tive in the social sciences (Goodchild et al. 2000). It was readily recognized that a major instrument in disseminating and facilitating spatial data analysis would be an

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
