KDV-Explorer: A Near Real-Time Kernel Density Visualization System for Spatial Analysis
Summary: KDV-Explorer enables near-real-time kernel density visualization and exploratory zooming, panning, and scaling over million-point spatial datasets. Built on efficient KDV computation, it demonstrates sub-5-second interaction and compares favorably with QGIS and ArcGIS. (summarized by gpt-5.6-luna on Jul 24 2026)
