SIMD-ified R-tree Query Processing and Optimization [PDF]
, 2023 The introduction of Single Instruction Multiple Data (SIMD) instructions in mainstream CPUs has enabled modern database engines to leverage data parallelism by performing more computation with a single instruction, resulting in a reduced number of instructions required to execute a query as well as the elimination of conditional branches.

Exploiting Information-centric Networking to Federate Spatial Databases [PDF]
IEEE Access, vol. 7, pp. 165248-165261, 2019, 2019 This paper explores the methodologies, challenges, and expected advantages related to the use of the information-centric network (ICN) technology for federating spatial databases. ICN services allow simplifying the design of federation procedures, improving their performance, and providing so-called data-centric security.

A Survey on Spatial Co-location Patterns Discovery from Spatial Datasets [PDF]
IJCTT 7(3):137-142, January 2014, 2014 Spatial data mining or Knowledge discovery in spatial database is the extraction of implicit knowledge, spatial relations and spatial patterns that are not explicitly stored in databases. Co-location patterns discovery is the process of finding the subsets of features that are frequently located together in the same geographic area.

Research of spatial database based on spatial database engine
SPIE Proceedings, 2007 With increasing demands of GIS applications system in a complex, integrated, and other areas, the spatial data are required rapid growth for the systems, and users are more and more on the demand spatial data. The method which traditional documents express spatial data is obviously unable to meet these needs.

Spatial and temporal landslide distributions using global and open landslide databases
Natural Hazards, 2023 Landslide databases are a potential tool for the analysis of landslide susceptibility, hazard, and risk. Additionally, the spatio-temporal distribution of landslides and their correlation with their triggering factors are inputs that facilitate the ...
