The visualization of spatial data has a long tradition in the fields of cartography and geographic information science. There are guidelines for the visualization of topographic and thematic data. Dynamic spatial processes, which are becoming important for the development of geographic information systems (GIS), demand visualization guidelines for processes. The objective of this paper is to find an assignment of dynamic visualization schemes, i.e., animations and dynamic symbols like arrows, to types of processes. Our means to identify the types of processes, which are the basis of this investigation, is the theory of partial differential equations (PDEs). This approach reveals three main types of processes: diffusion-like, wave-like, and steady-state processes. Our results show that for selecting an appropriate visualization schema we need to know whether the process changes over time and what kind of object the process affects.
