Earth observation (EO) data archives are significantly growing as a result of advances in satellite systems. As an example, remote sensing (RS) images acquired by ESA’s Sentinel satellites (which are a part of EU’s Copernicus program) reach the scale of more than 10 TB per day. The “big EO data” is a great source for information discovery and extraction for monitoring Earth from above. Thus, accurate and scalable techniques for RS image understanding, search and retrieval have recently emerged.

In this talk, a general overview on scientific and practical problems related to RS image characterization, indexing and search from massive archives will be initially discussed. Then, our recent developments that can overcome these problems will be presented.

A particular attention will be given to the metric learning and the graph structure driven deep hashing networks for scalable and accurate content-based indexing and retrieval of RS images.

Finally, BigEarthNet that is a new large-scale Sentinel-2 multispectral benchmark archive introduced to advance deep learning studies in RS will be presented.
