Quadtree Geospatial Index

Quadtrees enable efficient spatial queries by recursively partitioning 2D space. Essential for ride-matching, finding nearby drivers, and location-based services.

How Quadtrees Work

Spatial Partitioning

Space is recursively divided into 4 quadrants. Each node holds up to 4 points before splitting.

O(log n) Queries

Range queries prune entire branches that don't intersect, avoiding O(n) full scans.

Uber Use Case

Find nearby drivers for a rider request. Geospatial indexes enable fast location-based matching.
