The Italian Cadastral Information System: A Real-Life Spatio-Temporal DBMSccessible nation-wide through a WEB-based interface since September 1998 and the effectiveness of its use is demonstrated by the sharp increase in the number of requests managed during the first months: in January 1999 it has been used by more than 15.000 end-users.

Animating Spatiotemporal Constraint Databasesmetric polygons that represent a given linear constraint database. We also show how to animate objects defined by parametric polygons, analyze the computational complexity of animation, and present empirical data to demonstrate the efficiency of our approach.≠

A Framework ofa Generic Index for Spatio-Temporal Data in C,t one checking for spatial or temporal overlap of objects, the second one providing a hierarchical decomposition of the data space into subspaces. If, in addition, splitting of data objects is allowed we are able to define manageable node sizes, leading to an improved generic index similar to R+-trees or other derivations.

A Spatio-Temporal Taxonomy for the Representation of Spatial Set Behaviourseed new models to relate evolution of spatial entities linked by common properties and constraints or relationships. In transportation GIS, an activity-event matrix describes individual entity behaviours, travel activities and routes on a transportation network. On the other hand, modelling disaggre

Lifestyles — An Algebraic Approach to Change in Identityented as a set of snapshots consisting of identifiable objects and relations among objects. A database needs transaction time for the consistent management of temporal links among identifiers. Four basic operations affecting object identity are proposed: ., and .. Their compositions are either appli

The Honeycomb Model of Spatio-Temporal Partitionslizations of operations that are well-known for static spatial maps. We then define a small set of operations on spatio-temporal partitions that are powerful enough to express all these tasks and more. Spatio-temporal partitions combine the general notion of temporal objects and the powerful spatial
