Distance Oracle on Terrain Surface
Summary: Proposes SE, a space-efficient epsilon-approximate distance oracle for shortest-distance queries on terrain surfaces. Storing concise pairwise POI distances, SE delivers small construction time, compact oracle size, and fast queries with up to 2-5 orders of magnitude speedups over prior work.
