This repo contains an open implementation to run inference with DTACSNet models for atmospheric correction. This repo and trained models are released under a Creative Commons non-commercial licence licence

Install ⚙️:

pip install dtacs

Run:

from dtacs.model_wrapper import ACModel
model_atmospheric_correction = ACModel(model_name="CNN_corrector_phisat2")
model_atmospheric_correction.load_weights()

ac_output = model_atmospheric_correction.predict(l1c_toa_s2)

awesome atmospheric correction The figure above shows a sample of Sentinel-2 level 1C, DTACSNet model output and Sentinel-2 level 2A in the RGB (first row) and in the SWIR, NIR, Red (last row) composites.

See the inference tutorial for a complete example.
