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 ...
A New Method to Index and Store Spatio-Temporal Data
(2016-11-16)
[Abstract] We propose a data structure that stores, in a compressed way, object trajectories, which at the same time, allow to efficiently response queries without the need to decompress the data. We use a data structure, ...
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 ...
