Area and shape distortions in open-source discrete global grid systems

open access: yesBig Earth Data, 2022
A Discrete Global Grid System (DGGS) is a type of spatial reference system that tessellates the globe into many individual, evenly spaced, and well-aligned cells to encode location and, thus, can serve as a basis for data cube construction.

Reduced Quotient Cube: Maximize Query Answering Capacity in OLAP

open access: yesIEEE Access, 2021
The data cube is a critical tool for accelerating online analysis in big data. Due to its exponential space overhead, the quotient cube, as the main data cube compression approach, was proposed to significantly reduce the number of data cells if they are

3iCubing: An Interval Inverted Index Approach to Data Cubes

open access: yesIEEE Access, 2022
The increase in the amounts of information used to analyze data is problematic since the memory necessary to store and process it is getting quite big. The interval inverted index representation was developed to reduce the required memory to store data ...
