Foreword by Brian Berry

The publication of a definitive Encyclopedia of GIS that lays out many of the computer science/mathematics foundations of the field is a major event, the culmination of a half century of development. I was part of the earliest stirrings in the mid-1950s. A small group of geography graduate students at the University of Washington, William Garrison’s “space cadets,” began to assemble what became the foundations of contemporary spatial analysis and to refocus mathematical cartography while working with civil engineer Edgar Horwood on his attempts to use the printers of the time to produce grey-shaded maps. Our attention was captured by Sputnik, however, we didn’t anticipate that the US’s response, the rapid development of NASA and satellite systems, would be the key to the equally rapid development of remote sensing, or that global positioning would rewrite cartography. Among the innovations of the time were Torsten Hägerstrand’s first simulation models of space-time diffusion processes and early econometric interest in spatial autocorrelation. Both themes are now central to spatial analysis. The GIS focus shifted when Garrison, Marble and I relocated to the Chicago region. Garrison and I helped fund civil engineer Howard Fisher’s first generation computer graphics software, SYMAP I, and Marble and I organized NSF workshops to spread the word and drew together an initial overview of the field in Spatial Analysis. Fisher took his ideas to the Ford Foundation and a subseq
