Abstract: Remote sensing has enabled large-scale crop classification to understand agricultural ecosystems and estimate production yields. Since few years, machine learning is increasingly used for automated crop classification. However, most approaches apply novel algorithms to custom datasets containing information of few crop fields covering a small region and this often leads to poor models that lack generalization capability. Therefore in this work, inspired from the self-supervised learning approaches, we devised and compared different approaches for contrastive self-supervised learning using Sentinel2 and Planetscope data for crop classification. In addition, based on the dataset DENETHOR, we assembled our own dataset for the experiments.
