On past - time indexing of moving objects q
Tracking of mobile objects trajectories is one of many modern applications supported by Spatiotemporal databases. Within the context of this application, queries about the present, future or past positions of the objects need to be answered. Several indexing methods have been proposed to efficiently handle such spatiotemporal queries. In the current paper, we propose a method for indexing the h...
متن کاملEfficient Update Method for Indexing Locations of Moving Objects
Tracking the changing positions of moving objects is becoming increasingly feasible and necessary. However, traditional spatial index structures are not suitable for storing these positions because of numerous update operations. In this paper, we propose an efficient update method for indexing the locations of moving objects based on the R-tree. This technique updates the structure of the index...
متن کاملIndexing Objects Moving on Fixed Networks
The development of a spatiotemporal access method suitable for objects moving on fixed networks is a very attractive challenge due to the great number of real-world spatiotemporal database applications and fleet management systems dealing with this type of objects. In this work, a new indexing technique, named Fixed Network R-Tree (FNR-Tree), is proposed for objects constrained to move on fixed...
متن کاملA Network-Based Indexing Method for Trajectories of Moving Objects
Recently many researchers have focused on management of historical trajectories of moving objects due to numerous size of accumulated data over time. However, most of them are concentrated in Euclidean spaces with (x, y, t). In real world, moving objects like vehicles on transportation networks have constraints on their movements, and some of applications need to manage and query them. Previous...
متن کاملIndexing Large Moving Objects from Past to Future with PCFI+-Index
Ideally, moving object databases should handle the past, current and future positions of moving objects efficiently. However, existing indexes such as SEB-Tree, SETI-Tree, 2+3R-Tree, 23RT-Tree and etc. can only provide the capability for past and current query, and the others such as TPR-Tree, and TPR*-Tree can only provide the capability for current and future query. None of them can provide a...
