Cover Story: A substantial amount of satellite imaging data is produced daily in remote sensing (RS), and improved methodologies and applications are required to mass label images for downstream machine learning. Curating and labelling such datasets is a time-consuming task for RS specialists. The proposed approach utilises autoencoders for learnt feature representation and subsequent manifold projection algorithms for two-dimensional exploration. Users interact with the visualization and label clusters based on their domain knowledge. Re-application of manifold projection can interactively refine subsets of clusters and achieve better class separation. Evaluation of the approach is conducted on real-world remote sensing satellite image datasets and demonstrates its effectiveness in achieving efficient image tile labelling.
