SEN1-2 Dataset for Deep Learning in SAR-Optical Data Fusion published

In accordance with our terms of reference (SAR big data provided by Sentinel-1, fusion of SAR and complementary data), WG I/3 is happy to announce the publication of the SEN1-2dataset for the fostering of deep learning approaches in SAR-optical data fusion. SEN1-2consists of 282,384 pairs of corresponding Sentinel-1 SAR and Sentinel-2 optical image patches, collected from across the globe  and throughout all meteorological seasons. It is intended to support the introduction of computer vision approaches to multi-sensor remote sensing and can be used for studies on image matching, image-to-image translation, or image colorization, to name just a few examples.

The dataset will officially be released in the frame of the ISPRS TCI Mid-Term Symposium with a corresponding paper published in the ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences. Interested colleagues can already have a look at the paper preprint at The dataset can be downloaded from under a CC-BY license.
