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.

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 ...

Sentinel-2 diffuser on-ground calibration

SPIE Proceedings, 2013
The Sentinel-2 multi-spectral instrument (MSI) will provide Earth imagery in the frame of the Global Monitoring for Environment and Security (GMES) initiative which is a joint undertaking of the European Commission and the Agency. MSI instrument, under Astrium SAS responsibility, is a push-broom spectro imager in 13 spectral channels in VNIR and SWIR ...

Forest Type Classification with Multitemporal Sentinel-2 Data

2020 International Conferences on Internet of Things (iThings) and IEEE Green Computing and Communications (GreenCom) and IEEE Cyber, Physical and Social Computing (CPSCom) and IEEE Smart Data (SmartData) and IEEE Congress on Cybermatics (Cybermatics), 2020
There are limited numbers of studies addressing the forest status, extents, locations, types, and composition over a large area at the regional or national levels with high spatial resolution. Sentinel-2 satellites can obtain 10-to-60m multispectral imagery with high image acquisition frequency, and thus makes it possible to improve the performance of ...

Correction of the BRDF Effects on Sentinel-2 Ocean Images

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
Sentinel-2 (S2) satellite images present directional reflectance effects caused by the configuration of the 12 detectors of the Multispectral Instrument (MSI). These effects are more distinct over water bodies due to water optical properties and they are often described by the bidirectional reflectance distribution function (BRDF).
