Quadtrees are everywhere spatial data exists. Mapping services use quadtree-like tile pyramids to serve map tiles at different zoom levels (Bing's quadkey system, for example, addresses tiles as base-4 paths). Game engines use them for collision detection and visibility culling. Geographic information systems use spatial indexes to store and query spatial datasets. PostGIS uses GiST indexes (R-tree-style) for spatial queries on geometries, while PostgreSQL's core supports quadtree-like SP-GiST indexes for certain data types like points.

Finding these queries requires a different research approach than traditional keyword research. Rather than using tools that show search volume and competition metrics, you need to understand what questions your target audience actually asks AI models. This means thinking about their problems, concerns, and information needs, then formulating those as conversational queries. Tools like an LLM Query Generator can help by analyzing your content and suggesting relevant questions people might ask to find that information.
