In geospatial queries, the computational complexity of spatial joins is higher than that of ordinary equality queries, because they need to handle two-dimensional or even multi-dimensional proximity determination as well as precise geometric determination (such as polygon intersection and point-in-polygon), and the candidate set after coarse index filtering is often still far larger than the final result.

UnverifiedGeographic data requires precision, while itinerary planning requires humanized trade-offs, and the two are naturally suited to being split into different levels of execution.67% similarUnverifiedIn GIS, the determination of "adjacency" usually relies on topological relationships and buffer analysis, and determining a shared boundary requires the boundary lines of two polygons to coincide within a tolerance, which is often set according to data precision (for example, 1 meter or 3 meters).65% similarUnverifiedExact computation of geodesic distances typically requires solving differential equations, which is computationally expensive.65% similar
