Visualization of geographically-referenced observations to support real-time decision-making

Graphical presentation of data to support decision making has a long history, going back to the earliest use of maps and charts. Continued advances in technology have enabled development of a succession of powerful tools to support decision-making, providing visualization of geographically-referenced observations. Early geographic information systems (GIS) were succeeded by powerful (and affordable) systems. Military command and control systems, and air traffic control systems. demonstrated the value of visualization of real-time data in time-critical decision-making. Decision support systems today combine the functions of a GIS and aspects of command and control systems in a powerful and affordable context for real-time decision-making. The REINAS system is presented as a prototype of such a real-time decision-support systems exploiting real-time geographically-referenced measurements.
