Visual Reasoning: the Link Between User Interfaces and Map Visualisation for Geographic Information Systems
ByKeith Clarke
Pages 14

Two topics of heightened interest to geographic information scientists as GIS software reaches maturity are scientific visualisation and computer user interfaces. These areas of software development, with origins in computer graphics and in software engineering respectively, have now begun to merge their functions within GIS queries and displays. At first sight, they appear to occupy opposite ends of the spectrum of human-computer interaction. In the former case, a new branch of scientific inquiry has evolved in which the scientist views and interacts with the data in all its complexity directly, rather than with abstractions, generalisations or statistical descriptions (Freidhoff and Benzon, 1989; Keller and Keller, 1993).
