Spatial-temporal modeling and visualisation

─This paper considers a number of properties of space-time covariance functions and how these relate to the spatialtemporal interactions of the process. The processing of five temporal series is presented to show the difficulties to determine and visualize recognized space of object states. This work is focused on the temporal GIS that will be able to examine human activities under various constraints in a space–time context. The contribution of space-time geographical object understanding and the possibility to analyse the complex spatial-temporal relationships to improve cognitive processes is discussed. The object oriented approaches are inherently connected with object dynamics and activities resulting in interactions and this point of view can help us to understand space of states that could have significant implications to our everyday life.
