Efficient Processing of Raster and Vector Data
(Public Library of Science, 2020-01-10)
[Abstract] In this work, we propose a framework to store and manage spatial data, which includes new efficient algorithms to perform operations accepting as input a raster dataset and a vector dataset. More concretely, we ...
Efficient Representation of Multidimensional Data over Hierarchical Domains
(Springer, 2016-09-21)
[Abstract] We consider the problem of representing multidimensional data where the domain of each dimension is organized hierarchically, and the queries require summary information at a different node in the hierarchy of ...
Compact data structures for large and complex datasets
(2017)
[Abstract]
In this thesis, we study the problem of processing large and complex collections of
data, presenting new data structures and algorithms that allow us to efficiently store
and analyze them. We focus on three ...
