" "Many pressing problems facing science and society are inherently geospatial – location matters. The availability of essential geospatial data has increased dramatically over the past decade. Both scientific progress and application of geospatial information to societal needs remains hampered, however, due to the lack of methods for transforming these data into information and for combining information from diverse sources to construct knowledge. Progress requires fundamental breakthroughs in both geovisualization and its integration with other methods for geospatial knowledge construction. The research agenda delineated in this issue is a step toward achieving these breakthroughs. Identifying the challenges is the easy part. Meeting them is unlikely without a commitment to a coordinated approach, by both individuals and organizations in multiple countries.

Additional quotes by Alan MacEachren
The nature of maps and of their use in science and society is in the midst of remarkable change - change that is stimulated by a combination of new scientific and societal needs for geo-referenced information and rapidly evolving technologies that can provide that information in innovative ways. A key issue at the heart of this change is the concept of "visualization."
Geovisualization integrates approaches from visualization in scientific computing (ViSC), cartography, image analysis, information visualization, exploratory data analysis (EDA), and geographic information systems (GISystems) to provide theory, methods, and tools for visual exploration, analysis, synthesis, and presentation of geospatial data (any data having geospatial referencing).

During the 1960s and 1970s, when cartographers were embracing the communication model and a behavioral approach to empirical research, psychology was undergoing a revolution in its perspective on what to study and how to study it. Psychologists began to realize that stimulus-response laws do not explain human perception or behavior (any more than the gravity models used by geographers can explain spatial interaction).
