GBA-Facade: Benchmarking the GlobalBuildingAtlas for Autonomous Facade Maintenance at Planetary Scale

We present GBA-Facade, the first large-scale benchmark evaluating the GlobalBuildingAtlas (2.75B buildings) for autonomous facade maintenance planning. Includes real city-by-city benchmarks queried from PostgreSQL across 14 global tiles, with figures. Key findings: 87,731 buildings above 50m in 14 city regions with 1.14B m² of facade area. The Pearl River Delta tile alone accounts for 58,742 tall buildings.
