Indexing Land Surface for Efficient kNN Query
Summary: Proposes the Surface Index R-tree (SIR-tree) with Tight Surface Index (TSI) and Loose Surface Index (LSI) to support exact skNN on land surfaces. Supports a priori-k-free, incremental search with localized pruning, reporting exact shortest surface paths and outperforming baselines in efficiency and accuracy on real data.
