High Performance Computing in Satellite SAR Interferometry: A Critical Perspective
Remote Sensing - Tập 13 Số 23 - Trang 4756
Pasquale Imperatore, Antonio Pepe, E. Sansosti
Synthetic aperture radar (SAR) interferometry has rapidly evolved in the last decade and can be considered today as a mature technology, which incorporates computationally intensive and data-intensive tasks. In this paper, a perspective on the state-of-the-art of high performance computing (HPC) methodologies applied to spaceborne SAR interferometry (InSAR) is presented, and the different ...... hiện toàn bộ
Variations in Channel Centerline Migration Rate and Intensity of a Braided Reach in the Lower Yellow River
Remote Sensing - Tập 13 Số 9 - Trang 1680
Junqiang Xia, Yingzhen Wang, Meirong Zhou, Shanshan Deng, Zhiwei Li, Zenghui Wang
The Yellow River (YR) covers three climatic zones including arid region, semi-arid region and temperate monsoon region, with frequent appearance of flow intermittence in the Lower Yellow River (LYR) before 1999. Channel migration occurs frequently in braided rivers, which is a major focus of study in geomorphology and river dynamics. The braided reach in the LYR is featured by a complexly ...... hiện toàn bộ
Comparison of Retrieved L2 Products from Four Successive Versions of L1B Spectra in the Thermal Infrared Band of TANSO-FTS over the Arctic Ocean
Remote Sensing - Tập 9 Số 11 - Trang 1167 - 2017
Payan, Sébastien, Camy-Peyret, Claude, Bureau, Jérôme
This paper concentrates on the calibration/validation of the Thermal and Near Infrared Sensor for Carbon Observation (TANSO)–Fourier Transform Spectrometer (FTS) spectra in the thermal infrared (TIR) spectral region (B4 band) over the Arctic Ocean. We have performed inter-comparisons of the retrieved L2 products from four successive versions of L1B products (V150, V160, V201, V203) to check the di...... hiện toàn bộ
A Novel Privacy Approach of Digital Aerial Images Based on Mersenne Twister Method with DNA Genetic Encoding and Chaos
Remote Sensing - Tập 12 Số 11 - Trang 1893
Fawad Masood, Wadii Boulila, Jawad Ahmad, Arshad Ali, Syam Sankar, Saeed Rubaiee, William J. Buchanan
Aerial photography involves capturing images from aircraft and other flying objects, including Unmanned Aerial Vehicles (UAV). Aerial images are used in many fields and can contain sensitive information that requires secure processing. We proposed an innovative new cryptosystem for the processing of aerial images utilizing a chaos-based private key block cipher method so that the images ar...... hiện toàn bộ
Early Detection of Plant Physiological Responses to Different Levels of Water Stress Using Reflectance Spectroscopy
Remote Sensing - Tập 9 Số 7 - Trang 745
Matthew Maimaitiyiming, Vasit Sagan, Arianna Bozzolo, Joseph L. Wilkins, Misha T. Kwasniewski
Early detection of water stress is critical for precision farming for improving crop productivity and fruit quality. To investigate varying rootstock and irrigation interactions in an open agricultural ecosystem, different irrigation treatments were implemented in a vineyard experimental site either: (i) nonirrigated (NIR); (ii) with full replacement of evapotranspiration (FIR); or (iii) i...... hiện toàn bộ
High-Resolution Mapping of Urban Surface Water Using ZY-3 Multi-Spectral Imagery
Remote Sensing - Tập 7 Số 9 - Trang 12336-12355
Fangfang Yao, Chao Wang, Di Dong, Jiancheng Luo, Zhanfeng Shen, Kehan Yang
Accurate information of urban surface water is important for assessing the role it plays in urban ecosystem services under the content of urbanization and climate change. However, high-resolution monitoring of urban water bodies using remote sensing remains a challenge because of the limitation of previous water indices and the dark building shadow effect. To address this problem, we propo...... hiện toàn bộ
MERLIN: A French-German Space Lidar Mission Dedicated to Atmospheric Methane
Remote Sensing - Tập 9 Số 10 - Trang 1052 - 2017
Ehret, Gerhard, Bousquet, Philippe, Pierangelo, Clémence, Alpers, Matthias, Millet, Bruno, Abshire, James B., Bovensmann, Heinrich, Burrows, John P., Chevallier, Frédéric, Ciais, Philippe, Crevoisier, Cyril, Fix, Andreas, Flamant, Pierre, Frankenberg, Christian, Gibert, Fabien, Heim, Birgit, Heimann, Martin, Houweling, Sander, Hubberten, Hans W., Jöckel, Patrick, Law, Kathy, Löw, Alexander, Marshall, Julia, Agusti-Panareda, Anna, Payan, Sebastien, Prigent, Catherine, Rairoux, Patrick, Sachs, Torsten, Scholze, Marko, Wirth, Martin
The MEthane Remote sensing Lidar missioN (MERLIN) aims at demonstrating the spaceborne active measurement of atmospheric methane, a potent greenhouse gas, based on an Integrated Path Differential Absorption (IPDA) nadir-viewing LIght Detecting and Ranging (Lidar) instrument. MERLIN is a joint French and German space mission, with a launch currently scheduled for the timeframe 2021/22. The German S...... hiện toàn bộ
A 30+ Year AVHRR Land Surface Reflectance Climate Data Record and Its Application to Wheat Yield Monitoring
Remote Sensing - Tập 9 Số 3 - Trang 296
B. Franch, Éric Vermote, Jean‐Claude Roger, Emilie Murphy, Inbal Becker‐Reshef, Chris Justice, Martin Claverie, Jyoteshwar Nagol, Ivan Csiszar, David Meyer, Frédéric Baret, E. Masuoka, Robert E. Wolfe, Sadashiva Devadiga
The Advanced Very High Resolution Radiometer (AVHRR) sensor provides a unique global remote sensing dataset that ranges from the 1980s to the present. Over the years, several efforts have been made on the calibration of the different instruments to establish a consistent land surface reflectance time-series and to augment the AVHRR data record with data from other sensors, such as the Mode...... hiện toàn bộ
Spatiotemporal Dynamics and Driving Forces of Urban Land-Use Expansion: A Case Study of the Yangtze River Economic Belt, China
Remote Sensing - Tập 12 Số 2 - Trang 287
Yang Zhong, Aiwen Lin, Lijie He, Zhigao Zhou, Moxi Yuan
It is important to analyze the expansion of an urban area and the factors that drive its expansion. Therefore, this study is based on Defense Meteorological Satellite Program Operational Linescan System (DMSP/OLS) night lighting data, using the landscape index, spatial expansion strength index, compactness index, urban land fractal index, elasticity coefficient, the standard deviation elli...... hiện toàn bộ
Can GNSS-R Detect Abrupt Water Level Changes?
Remote Sensing - Tập 12 Số 21 - Trang 3614
Sajad Tabibi, Olivier Francis
Global navigation satellite system reflectometry (GNSS-R) uses signals of opportunity in a bi-static configuration of L-band microwave radar to retrieve environmental variables such as water level. The line-of-sight signal and its coherent surface reflection signal are not separate observables in geodetic GNSS-R. The temporally constructive and destructive oscillations in the recorded sign...... hiện toàn bộ
