Three Geomedia

Abstract

Working on the same principles as the phonograph, but reading tremblings of the ground rather than of the air, scratching out in real time invisible actions in visible form, the seismograph betrays its origins in the mechanical era. Today a second, more arithmetic form of data visualisation diagrams a numerical data set such as the one derived from instrument systems in place to monitor the health of the Animas River. A third form, financial visualisation software in commodity markets, not only gives direct accounts of geology (reserves), human interventions in them (extraction) and simulations of their likely use (futures) but actively produce those futures by fixing future trading prices. ..
