• Abstract: Nowadays, there is a general agreement on the need to better characterize agricultural monitoring systems in response to the global changes. Timely and accurate land use/land cover mapping can support this vision by providing useful information at fine scale. Here, a deep learning approach is proposed to deal with multi-source land cover mapping at object level. The approach is based on an extension of Recurrent Neural Network enriched via an attention mechanism dedicated to multi-temporal data context. Moreover, a new hierarchical pretraining strategy designed to exploit specific domain knowledge available under hierarchical relationships within land cover classes is introduced. Experiments carried out on the Reunion island - a french overseas department - demonstrate the significance of the proposal compared to remote sensing standard approaches for land cover mapping.

  Open-set single-source domain generalization aims to use a single-source domain to learn a robust model that can be generalized to unknown target domains. We propose a novel learning approach based on domain expansion and boundary growth to expand the scarce source samples. Our approach can achieve significant improvements and reach state-of-the-art performance on several cross-domain image classification datasets.

  We propose to combine fully labeled source domain and weakly labeled target domain for weakly supervised domain adaptation (WSDA) This is beneficial as the utilization of sparse and coarse weak labels can considerably alleviate the labor required for precise and detailed land cover annotation. We carry out high categorical resolution land cover mapping for 10 cities in different regions around the world, severally using PlanetScope, Gaofen-1, and Sentinel-2 satellite images.

  Land use/land cover (LULC) maps play a pivotal role in supporting agricultural territory management, environmental monitoring and sustainable decision-making. New ground truth data must be collected, leading to the complete disregard of previously gathered reference data. We propose a deep learning framework to combine remote sensing and reference data coming from two different domains.

  We argue to rethink the sensor's dependency modeling from two hierarchies: regional and global. We generate representative and common-temporal patterns as global nodes to reflect a global dependency between sensors. In pursuit of the generality of reality of node representations, we incorporate a Meta GCN to propagate and global nodes in the physical data space.

  We present Embedding Earth a self-supervised contrastive pre-training method for leveraging the large availability of satellite imagery.

We find that learnt features can generalize between disparate regions opening up the possibility of using the proposed pre-training scheme.
