Oil Palm Deep Learning (OPDL)

This is a repository for oil palm semantic segmentation from Sentinel-1 SAR and/or Sentinel-2 MS using fully convolutional neural network U-Net. The project was part of my MSc thesis supervised by Iris van Duren and Raian V. Maretto. The model was trained on University of Twente's CRIB.

The oil palm label was obtained from high-resolution oil palm map by Descals et al. 2021.
