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 ...

Exploring Sentinel-1 and Sentinel-2 diversity for Flood inundation mapping using deep learning

, 2021
Identification of flood water extent from satellite images has historically relied on either synthetic aperture radar (SAR) or multi-spectral (MS) imagery. But MS sensors may not penetrate cloud cover, whereas SAR is plagued by operational errors such as

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 ...

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 ...

Wind Turbine Detection on Sentinel-2 Images

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
ESA's Sentinel- 2 satellites have been in orbit for five years, acquiring huge amounts of data all over the world. They are a formidable tool for mass detection as they are freely available. Given their importance in the energetic transition and their spread over countries or continents, wind turbines are natural candidates for such studies. We propose

Mapping Forest Height and Aboveground Biomass by Integrating ICESat‐2, Sentinel‐1 and Sentinel‐2 Data Using Random Forest Algorithm in Northwest Himalayan Foothills of India

Geophysical Research Letters, 2021
The present study aims to map forest canopy height by integrating ICESat‐2 and Sentinel‐1 data and investigate the effect of integrating forest canopy height information with Sentinel‐2 data‐derived spectral variables on the prediction of spatial ...

Potential of ESA's Sentinel-2 for geological applications

Remote Sensing of Environment, 2014
Abstract Sentinel-2 is ESA's medium spatial resolution (10–60 m) super-spectral instrument aimed at ensuring data continuity for global land surface monitoring of Landsat and SPOT. Several simulation studies have been conducted that show the potential of Sentinel-2 for estimating biophysical and biochemical parameters such as leaf area index ...

Multitemporal Sentinel-2 data - remarks and observations

2017 9th International Workshop on the Analysis of Multitemporal Remote Sensing Images (MultiTemp), 2017
All the pre-processing algorithms are being improved constantly. The biggest challenge for the multitemporal analysis is to deal with errors caused directly by the chain of pre-processing of raw Sentinel-2 data to the level L1C - misregistration of pixels.
