Abstract
We introduce a visual language for the specification of temporally changing spatial situations. The main idea is to represent spatio-temporal (ST) objects in a two-dimensional way by their trace. The intersections of these traces with other objects are interpreted and translated into sequences of spatial and spatio-temporal predicates, called developments, that can then be used, for example, to query spatiotemporal databases. 1. ST Objects, Predicates, and Developments Spatio-temporal objects like flying airplanes, migrating whales, or spreading fires have the characteristic property that they are spatial entities changing over time and that these changes are continuous. For the modeling of these data the concept of spatio-temporal data types [1] has been
