Hierarchically Organized Skew-Tolerant Histograms for Geographic Data Objects

Summary: Proposes STHistogram, a skew-tolerant histogram for 2D/3D geographic data objects, delivering robust accuracy under highly skewed distributions. It detects hotspots and uses them to guide bucketization, yielding tighter cardinality estimates and superior performance to prior histograms. (summarized by gpt-5-nano on Feb 09 2026)
