EAR-Oracle: On Efficient Indexing for Distance Queries between Arbitrary Points on Terrain Surface
Summary: EAR-Oracle: an index-based distance oracle for arbitrary point-to-point terrain queries, eliminating the need for predefined POIs. It provides guarantees on accuracy, build-time/size, and query-time; scales to massive terrains and delivers orders-of-magnitude faster query performance than prior online methods.
