GHS-SDGSAT R2025A – Global Human Settlement SDGSAT-1 Nighttime Light

High-resolution nighttime light (NTL) composite from SDGSAT-1. The composites generated aim to minimize contamination from atmospheric conditions, moonlight reflection, and sensor anomalies, while maximizing the similarity of aggregated SDGSAT-1 NTL data with existing, calibrated annual VIIRS composites by leveraging structural image features and a ranking-based compositing approach. The dataset consist in a series of raster data including the model final and intermediate outputs.
