HiIndex: An Efficient Spatial Index for Rapid Visualization of Large-Scale Geographic Vector Data
ISPRS International Journal of Geo-Information, 2021 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-
