Moving Objects and Their Equations of Motion
Moving objects are currently represented in databases by means of an explicit representation of their trajectory. However from a physical point of view, or more specifically accor...

Querying the Uncertain Position of Moving Objects
In this paper we propose a data model for representing moving objects with uncertain positions in database systems. It is called the Moving Objects Spatio-Temporal (MOST) data mod...

Partition-based lazy updates for continuous queries over moving objects
Continuous spatial queries posted within an environment of moving objects produce as their results a time-varying set of objects. In the most ambitious case both queries and data ...

Adaptive Safe Regions for Continuous Spatial Queries over Moving Objects
Abstract. Continuous spatial queries retrieve a set of time-varying objects continuously during a given period of time. However, monitoring moving objects to maintain the correctne...

Aggregation languages for moving object and places of interest
We address aggregate queries over GIS data and moving object data, where non-spatial information is stored in a data warehouse. We propose a formal data model and query language t...
