Efficient Point‑in‑Polygon Determination for Geo‑fencing Using Ray Casting and R‑Tree Indexing
The article explains how geo‑fencing relies on fast point‑in‑polygon checks, compares the basic ray‑casting method with brute‑force performance, and shows how spatial R‑tree indexing—both on polygon bounding boxes and on individual edges—dramatically speeds up queries even for millions of complex polygons.
