Copernicus SENTINEL-2 Geometric Calibration Status

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The Sentinel-2 mission is a key element of the Copernicus Earth monitoring program of the European Union. The mission is currently composed of two satellites and provides a continuous observation of land and coastal areas at high spatial resolution and with a revisit time of 5 days at the equator.

Sentinel 2 global reference image

SPIE Proceedings, 2015
Sentinel-2 is a multispectral, high-resolution, optical imaging mission, developed by the European Space Agency (ESA) in the frame of the Copernicus program of the European Commission. In cooperation with ESA, the Centre National d’Etudes Spatiales (CNES) is responsible for the image quality of the project, and will ensure the CAL/VAL commissioning ...

Ice floe tracking with Sentinel-2

Remote Sensing of the Ocean, Sea Ice, Coastal Waters, and Large Water Regions 2020, 2020
Sentinel-2 offers the capabilities to observe Arctic sea ice features with high spatial and temporal resolution. Arctic sea ice drift, however, exacerbates observing the temporal evolution of floes by means of time series analysis. We therefore developed a novel rotation-invariant ice floe descriptor based on ice floe geometry and an image-processing ...

Sentinel-2 Change Detection Based on Deep Features

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
In this manuscript, we address the problem of change detection for Sentinel-2 data. The proposed method is based on deep features representation. First, multilevel convolutional neural network (CNN) features are extracted from input images acquired at different times.
