Evaluation of the potential of Sentinel-1 and Sentinel-1 data for clay content mapping [PDF]

, 2020
<p>Soil texture is a key parameter in agricultural processes and an important measure for agricultural prediction, water cycle, filtering of pollutants and carbon storage. Besides, its estimation is essential for agronomists, hydrologists, geologists and environmentalists and for modeling in these application areas.

Sentinel-1 Support in the GAMMA Software [PDF]

Procedia Computer Science, 2015
AbstractFirst results using the new Sentinel-1 SAR look very promising but the special interferometric wide-swath data acquired in the TOPS mode makes InSAR processing more challenging than for normal stripmap mode data. The steep azimuth spectra ramp in each burst results in very stringent co-registration requirements.

Sentinel-1 for Monitoring Reservoirs: A Performance Analysis [PDF]

Remote Sensing, 2014
In this paper we explore the performances and the opportunities provided by the European satellite Sentinel-1 for water resource management applications in low-income countries. The analysis is supported by a synthetic aperture radar (SAR) simulator, which allowed the quantification of the expected characteristics of Sentinel-1 products in three ...

PARKING OCCUPANCY ESTIMATION ON SENTINEL-1 IMAGES [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Abstract. This paper presents a method to estimate the occupancy ratio of parkings from SAR satellite images. The algorithm takes as input a series of Sentinel-1 images along with a mask indicating where the parking is located and returns for each image an occupancy ratio. The method is generic and can easily be extended. We validate our results in two

Sentinel-1 Mission Status

Procedia Computer Science, 2016
AbstractAs part of the European Copernicus programme, the Sentinel-1 mission, based on a constellation of two SAR satellites, ensures continuity for Europe of C-band SAR observations. Sentinel-1A and Sentinel-1B were respectively launched from Kourou on 3rd April 2014 and 25th April 2016.Full Operations Capacity (FOC) of the mission is expected to be ...

Detecting Irrigation Events Using Sentinel-1 Data [PDF]

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
Better management of water consumption in irrigated agriculture is essential in order to save water resources. The objective of this study is to propose a new model capable of detecting the irrigation events using the Sentinel-1 (S1) C-band SAR (synthetic-aperture radar) in a near real-time approach.

Observing Sucrose Accumulation With Sentinel-1 Backscatter [PDF]

Frontiers in Remote Sensing, 2021
In this study the impact of sucrose accumulation in Sentinel-1 backscatter observations is presented and compared to Planet optical observations. Sugarcane yield data from a sugarcane plantation in Xinavane, Mozambique are used for this study. The database contains sugarcane yield of 387 fields over two seasons (2018-2019 and 2019-2020).

Crop NDVI Monitoring Based on Sentinel 1 [PDF]

Remote Sensing, 2019
Monitoring agricultural crops is necessary for decision-making in the field. However, it is known that in some regions and periods, cloud cover makes this activity difficult to carry out in a systematic way throughout the phenological cycle of crops. This circumstance opens up opportunities for techniques involving radar sensors, resulting in images ...

Deformation Monitoring Using Sentinel-1 SAR Data [PDF]

The 2nd International Electronic Conference on Remote Sensing, 2018
This paper describes the data processing and analysis procedure implemented by the authors to analyse Sentinel-1 data. The procedure is an advanced Differential Interferometric SAR (DInSAR) technique that generates deformation maps and time series of deformation from multiple SAR images acquired over the same site.
