Space- and Time-Efficient Storage of LiDAR Point Clouds
Susana Ladra, Miguel R. Luaces, José R. Paramá +1
LiDAR devices obtain a 3D representation of a space. Due to the large size of the resulting datasets, there already exist storage methods that use compression and present some prop…
GraCT: A Grammar-based Compressed Index for Trajectory Data
Nieves R. Brisaboa, Adrián Gómez-Brandón, Gonzalo Navarro +1
We introduce a compressed data structure for the storage of free trajectories of moving objects (such as ships and planes) that efficiently supports various spatio-temporal queries…
A Grammar-based Compressed Representation of 3D Trajectories
Nieves R. Brisaboa, Adrián Gómez-Brandón, Miguel A. Martínez-Prieto +1
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. Howeve…
Towards a compact representation of temporal rasters
Ana Cerdeira-Pena, Guillermo de Bernardo, Antonio Fariña +2
Big research efforts have been devoted to efficiently manage spatio-temporal data. However, most works focused on vectorial data, and much less, on raster data. This work presents…
Relative compression of trajectories
Nieves R. Brisaboa, Travis Gagie, Adrián Gómez-Brandón +2
We present RCT, a new compact data structure to represent trajectories of objects. It is based on a relative compression technique called Relative Lempel-Ziv (RLZ), which compresse…
Efficient Compression and Indexing of Trajectories
Nieves R. Brisaboa, Travis Gagie, Adrián Gómez-Brandón +2
We present a new compressed representation of free trajectories of moving objects. It combines a partial-sums-based structure that retrieves in constant time the position of the ob…
