AGB estimation using Sentinel-2 and Sentinel-1 datasets

Environmental Monitoring and Assessment
Climate change is one of the greatest threats recently, of which developing countries are facing most of the brunt. In the fight against climate change, forests can play an important role, since they hold a substantial amount of terrestrial carbon and can therefore affect the global carbon cycle.

Mediterranean shrublands biomass estimation using Sentinel-1 and Sentinel-2

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
Potential for synergetic use of Sentinel- 1 and Sentinel-2 for mapping biomass of Mediterranean shrublands is investigated. As preliminary research, backscatter and its ratio from Sentinel-1 (C-band dual polarization SAR), and NDVI from Sentinel-2 (13 bands multi-spectral data) are assessed by using the NDVIR biomass model.

Mountain crop monitoring with multitemporal Sentinel-1 and Sentinel-2 imagery

2017 9th International Workshop on the Analysis of Multitemporal Remote Sensing Images (MultiTemp), 2017
An analysis of radar signal sensitivity to crop and soil conditions was conducted using a time series of Sentinel-1 C-band dual-polarized (VH-VV) SAR images acquired from October 2014 to September 2016 for different crops (meadows, pasture, orchard, vineyards) located in mountain areas.

Sentinel-1 and Sentinel-2 Data Fusion for Urban Change Detection

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
In this paper a new approach based on the fusion of Sentinel-1 and Sentinel-2 products to map urban change detection and to observe suburb's development is presented. The algorithm developed can process data in a fast, automatic and accurate way. To reach this goal, the processing chain uses an iterative multitemporal approach based, for each iteration,

Coupling Sentinel-1 and Sentinel-2 Images for Operational Soil Moisture Mapping

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
The objective of the present paper is to develop an operational approach for soil moisture mapping in agricultural areas at a high spatial resolution over bare soils, as well as soils with vegetation cover. The developed approach is based on the synergic use of radar and optical data and uses the neural network technique to invert the radar signal ...

Evaluation of Burnt Building Damage Using Sentinel-1 and Sentinel-2 Data

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
Intensive wildfire is one of the catastrophic hazards threatening human life and the economy. In this study, we aim to detect building damage caused by the Camp Fire, which occurred in Paradise, California in 2018. We use multitemporal coherence based on C-band Sentinel-1 (SAR) and normalized burn ratio based on Sentinel-2 (multispectral) imagery.

Use of Sentinel-l and Sentinel-2 for Monitoring Illegal Fishing Off Ghana

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
An efficient and inexpensive service has been developed for the monitoring of fishing vessels in West Africa using Earth Observation (EO) data. The service makes use of fast-delivery data from the Synthetic Aperture Radar (SAR) instrument on Sentinel-l and the Multi Spectral Imager (MSI) on Sentinel-2, detecting objects that differ markedly from their ...

Crop-Identification Using Sentinel-1 and Sentinel-2 Data for Indian Region

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
Real-time monitoring of agricultural crops is an important exercise because of the huge economic impact. Identification of crop during early stage of the crop cycle can help formulate better agriculture policies and management strategies. In this context, the objective of this article is to evaluate the potential of Sentinel-1 Synthetic Aperture Radar (
