HiIndex: An Efficient Spatial Index for Rapid Visualization of Large-Scale Geographic Vector Data
In the big data era, rapid visualization of large-scale vector data has become a serious challenge in Geographic Information Science (GIS). To fill the gap, we propose HiIndex, a spatial index that enables real-time and interactive visualization of large-

SPAG: Index of spatial agglomeration
The paper develops a spatial agglomeration index (SPAG) of the economic activity for the point geo‐localizations of firms. It includes the effects of location, the distance between firms and the overlapping impact of the firms' size. The SPAG builds a new class of measures of the spatial density of the economic activity inside the region, based on the ...

A Spatial Index Based on Clipping Bounding Box of Space Partitioning Tree [PDF]
In spatial databases, spatio-temporal indexes based on R tree use minimum bounding box(MBB)to approximate spatio-temporal data to improve query efficiency, and the efficiency of indexing can be further improved by by clipping the bounding box.To ...

Efficient processing of spatial joins is very important due to their high cost and frequent application in spatial databases and other areas involving multidimensional data. This paper proposes slot index spatial join (SISJ), an algorithm that joins a nonindexed data set with one indexed by an R-tree.
