GraCT: A Grammar Based Compressed Representation of Trajectories
(Springer, 2016-09-21)
[Abstract] We present a compressed data structure to store free trajectories of moving objects (ships over the sea, for example) allowing spatio-temporal queries. Our method, GraCT, uses a k2k2 -tree to store the absolute ...
GraCT: A Grammar-based Compressed Index for Trajectory Data
(Elsevier Ltd, 2019)
[Abstract]: We introduce a compressed data structure for the storage of free trajectories of moving objects that efficiently supports various spatio-temporal queries. Our structure, dubbed GraCT, stores the absolute positions ...
Lossless Compression of Industrial Time Series With Direct Access
(Elsevier, 2021)
[Abstract] The new opportunities generated by the data-driven economy in the manufacturing industry have causedmany companies opt for it. However, the size of time series data that need to be captured creates theproblem ...
Scalable processing and autocovariance computation of big functional data
(John Wiley & Sons, 2018)
[Abstract]: This paper presents 2 main contributions. The first is a compact representation of huge sets of functional data or trajectories of continuous-time stochastic processes, which allows keeping the data always ...
An index for moving objects with constant-time access to their compressed trajectories
(Taylor & Francis, 2021)
[Abstract]: As the number of vehicles and devices equipped with GPS technology has grown explosively, an urgent need has arisen for time- and space-efficient data structures to represent their trajectories. The most commonly ...
3DGraCT: A Grammar-Based Compressed Representation of 3D Trajectories
(Springer, 2018)
[Abstract]: Much research has been published about trajectory management on the ground or at the sea, but compression or indexing of flight trajectories have usually been less explored. However, air traffic management is ...
