HLS-GPT Transformer reconstructs NASA satellite reflectance data

Researchers have developed HLS-GPT, a large-scale generative pretrained Transformer model designed to reconstruct NASA's Harmonized Landsat and Sentinel-2 (HLS) surface reflectance data. This model utilizes a hierarchical Transformer architecture to process varying spectral band configurations and operates on single-pixel time series. Trained on extensive data from the conterminous United States, HLS-GPT demonstrates robust reconstruction capabilities across diverse land surface conditions and outperforms conventional methods and the NASA-IBM Prithvi model in evaluations. AI

IMPACT This model advances AI's capability in processing and reconstructing complex satellite imagery for environmental monitoring.

RANK_REASON The cluster describes a new research paper detailing a novel AI model for satellite data reconstruction.
