A Fast Line Density Visualization Plugin for Geographic Information Systems
Summary: Fast Line Density Analysis is a QGIS plugin that provides scalable line-density visualization via epsilon-LDV and tau-LDV with guaranteed error bounds. It handles large datasets (up to 15.7M segments) and offers tunable accuracy–speed tradeoffs, outperforming naive GIS. (summarized by gpt-5-nano on Feb 09 2026)
