Hierarchical Spatial Indexing

Hierarchical spatial indexing is a way to organize and divide large geographical areas into smaller, manageable sections in a structured, layered system. Think of it like a map divided into grids, where each grid can be further subdivided into smaller grids, creating a hierarchy. This method allows for quick and efficient searching, storage, and retrieval of spatial data—like locations or features—by zooming into the relevant area without scanning the entire map. It’s used in applications such as GPS, geographic information systems (GIS), and location-based services to handle complex spatial information efficiently.
