Using Java Topology Suite (JTS) for Spatial Geometry Operations and Fast Point‑in‑Polygon Checks

This article introduces the Java Topology Suite (JTS), explains its core geometry models, WKT format, spatial relations, and operations, and demonstrates how to efficiently determine whether a point lies within service coverage polygons using MBR filtering, spatial indexes such as R‑tree and Quadtree, and geometry repair techniques.
