Research
Tobler was one of the principal investigators and a senior scientist in the National Science Foundation-sponsored National Center for Geographic Information and Analysis. He has used computers in geographic research since the 1960s, with emphasis on mathematical modeling and graphic interpretations. Well known for his publications, he formulated the "first law of geography" in 1970 while producing a computer movie, and is the inventor of novel and unusual map projections, among which was the first derivation of the partial differential equations for area cartograms. He also invented a method for smooth two-dimensional mass-preserving areal data redistribution. In 1989, the American Geographical Society awarded Tobler with the Osborn Maitland Miller Medal.
Tobler has been involved recently in building a global, latitude-longitude oriented, demographic information base with resolution two orders of magnitude better than was previously available. He also had been examining the development of smooth finite element and categorical pycnophylactic geographic information reallocation models. In July 1999 he presented a keynote speech, "The World is Shriveling as it Shrinks," at the ESRI International User Conference, and was the recipient of a Lifetime Achievement Award in GIS by ESRI. Taylor and Francis of London recently published a map projection book, co-authored with Q. Yang of China and the late John P. Snyder. Current interests relate to ideas in computational geography including the analysis of geographical vector fields and the development of migration and of global trade models.
Tobler has also been concerned with the representing flow (due to its involvement with movement as a mechanism of geographic change). In 2003, Tobler released a freeware, Microsoft Windows-based version of his flow representation software Flow Mapper. In 2005, an ESRI ArcGIS version of the software, inspired by Tobler, was developed by John Alan Glennon and Michael Frank Goodchild at UCSB. Both versions are available from the Center for Spatially Integrated Social Science (web)

Famous quotes containing the word research:
“Our science has become terrible, our research dangerous, our findings deadly. We physicists have to make peace with reality. Reality is not as strong as we are. We will ruin reality.”
—Friedrich Dürrenmatt (1921–1990)
“After all, the ultimate goal of all research is not objectivity, but truth.”
—Helene Deutsch (1884–1982)
“Men talk, but rarely about anything personal. Recent research on friendship ... has shown that male relationships are based on shared activities: men tend to do things together rather than simply be together.... Female friendships, particularly close friendships, are usually based on self-disclosure, or on talking about intimate aspects of their lives.”
—Bettina Arndt (20th century)
