3D Modeling Moving Objects under Uncertainty Conditions
Geospatial information systems (GIS) have been applied in modeling environmental and ecological systems. 3D Moving objects are spatiotemporal objects whose location and/or extent change over time, and they are among those recent evolutions that emerged to fulfill some of the new requirements for GI community. Many of the earlier works were based on the assumption that exact trajectory informati...
متن کاملQuerying Moving Objects with Uncertainty in Spatio-Temporal Databases
Spatio-temporal uncertainty is a special feature of moving objects due to the inability of precisely capturing or predicting their continuously changing locations. Indeterminate locations of moving objects at time instants add uncertainty to their topological relationships. Spatio-temporal uncertainty is important in many applications, for example, to determine whether two moving objects could ...
متن کاملProbabilistic measurement of uncertainty in moving objects databases
The representation of moving objects in spatial database systems has become an important research topic in recent years. As it is not realistic to track and store the location of objects at every time instant, one of the issues that has been raised in this domain has to do with handling uncertainty in the location of moving objects. There are several works proposing to enrich spatiotemporal lan...
متن کاملThe Geometry of Uncertainty in Moving Objects Databases
This work addresses the problem of querying moving objects databases. which capture the inherent uncertainty associated with the location of moving point objects. We address the issue of modeling, constructing, and querying a trajectories database. We propose to model a trajectory as a 3D cylindrical body. The model incorporates uncertainty in a manner that enables efficient querying. Thus our ...
