摘要：All entities in an urban environment such as buildings, parks, roads etc. are changing more or less over time. A seamless documentation of these changes in a spatiotemporal city model may require extraordinarily large storage capacity and a high computing intensity if the stored changes are visualized. This paper presents a mathematical model for defining and capturing the relative significance of events from various changes. The model is established on the basis of the inherent dependence that exists between the spatial and temporal scales or resolutions. Experiments show that changes can be evaluated and differentiated using their values of event significance on different occasions (with a certain temporal and spatial resolution)
