Satellite data integration yields accurate building height estimates for Global South cities

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a method for estimating building heights at an individual footprint scale, particularly for urban areas in the Global South where detailed data like LiDAR is scarce. By integrating data from TerraSAR-X StripMap, PlanetScope, and Sentinel-1 satellites, they employed a geographically weighted random forest model. This approach achieved an RMSE of 5.34 m and an R2 of 0.756 against a LiDAR reference, demonstrating that different satellite sensors and derived features have varying predictive relevance across different urban contexts and building types. AI

IMPACT Provides a cost-effective method for obtaining detailed urban height data, crucial for urban planning and disaster assessment in data-scarce regions.

RANK_REASON The cluster contains an academic paper detailing a new methodology for building height estimation using satellite data.
