Multi-modal Supervised Change Detection Data

The Multi-modal Change Detection Data Set [1] provides Sentinel-1 dual-pol SAR measurements to complement the hand-labeled ONERA change detection data set of optical satellite observations [2]. Our data set consists of bi-temporal and full-scene SAR images for 24 globally distributed regions of interest. The full-scene images are geo-referenced, time-aligned and co-registered to the optical ONERA data [2] and provided in the form of 16-bit GeoTiffs containing the following information: - Sentinel-1 SAR: 2 channels corresponding to sigma nought backscatter values in dB scale for VV and VH polarization.
