摘要

The Landsat-8 and Sentinel-2 sensors provide multi-spectral image data with similar spectral and spatial characteristics that together provide improved temporal coverage globally. Both systems are designed to register Level 1 products to a reference image framework, however, the Landsat-8 framework, based upon the Global Land Survey images, contains residual geolocation errors leading to an expected sensor-to-sensor misregistration of 38 m (24 These misalignments vary geographically but should be stable for a given area. The Landsat framework will be readjusted for consistency with the Sentinel-2 Global Reference Image, with completion expected in 2018. In the interim, users can measure Landsat-to-Sentinel tie points to quantify the misalignment in their area of interest and if appropriate to reproject the data to better alignment.

Improving Co-Registration for Sentinel-1 SAR and Sentinel-2 Optical Images

Yuanxin Ye, Chao Yang, Bai Zhu, Liang Zhou, Youquan He, Huarong Jia

Summary: Co-registering Sentinel-1 SAR and Sentinel-2 optical images is crucial for remote sensing applications, but misregistration shifts are common. This paper proposes a fast and effective registration method using block-based interest points extraction and similarity-based feature detection for accurate co-registration. Experimental results demonstrate that the third-order polynomial model achieves the best registration accuracy among the tested geometric transformation models.

Spatial and Spectral Translation of Landsat 8 to Sentinel-2 Using Conditional Generative Adversarial Networks

Rohit Mukherjee, Desheng Liu

Summary: In this study, a conditional generative adversarial network (CGAN) is developed to translate observations from Landsat 8 OLI (L8) to Sentinel-2 MSI (S2) imagery, improving data availability for earth monitoring. Two translation methodologies-direct single-step translation and indirect multistep translation-are employed, and the results show that the multistep approach achieves higher spectral fidelity and spatial correlation compared to the original L8 bands. This research validates the effectiveness of CGANs for cross-sensor domain adaptation and provides a reusable computational framework for satellite image translation.

Harmonizing surface reflectance between Landsat-7 ETM + , Landsat-8 OLI, and Sentinel-2 MSI over China

Hongye Cao, Ling Han, Liangzhi Li

Summary: This study evaluates the potential of integrating surface reflectance data from Landsat-7, Landsat-8, and Sentinel-2. A cross-sensor conversion model is proposed to adjust the Sentinel-2 reflectance values to match Landsat-7 or Landsat-8, reducing the discrepancy in surface reflectance. The study suggests that it is feasible to integrate these datasets by applying a linear regression correction between the bands.

Field Scale Assessment of the TsHARP Technique for Thermal Sharpening of MODIS Satellite Images Using VENμS and Sentinel-2-Derived NDVI

Lorena N. Lacerda, Yafit Cohen, John Snider, Hanna Huryna, Vasileios Liakos, George Vellidis

Summary: Remotely sensed-based surface temperature is important for crop monitoring and irrigation management, but current thermal satellite platforms lack the fine spatial resolution needed to identify crop water status patterns at the field scale. The TsHARP method provides a technique for downscaling coarse thermal images to match the finer resolution of visible and near infrared images. This study shows that using the TsHARP method can improve irrigation management efficiency.

Near real-time monitoring of tropical forest disturbance by fusion of Landsat, Sentinel-2, and Sentinel-1 data

Xiaojing Tang, Kelsee H. Bratley, Kangjoon Cho, Eric L. Bullock, Pontus Olofsson, Curtis E. Woodcock

Summary: The frequency of usable satellite observations is crucial for rapid detection of forest disturbance. Combining optical and SAR data provides the most usable observations in the tropics and enables more timely detection of forest disturbance. A new algorithm called Fusion Near Real-Time (FNRT) has been developed to monitor tropical forest disturbance by combining Landsat, Sentinel-2, and Sentinel-1 data, achieving high accuracy in detecting forest disturbances within short time frames.

Mapping Daily Evapotranspiration at Field Scale Using the Harmonized Landsat and Sentinel-2 Dataset, with Sharpened VIIRS as a Sentinel-2 Thermal Proxy

Jie Xue, Martha C. Anderson, Feng Gao, Christopher Hain, Yun Yang, Kyle R. Knipper, William P. Kustas, Yang Yang

Low-amplitude brittle deformations revealed by UAV surveys in alluvial fans along the northwest coast of Lake Baikal: Neotectonic significance and geological hazards

Oksana V. Lunina, Anton A. Gladkov, Alexey V. Bochalgin

Summary: In this study, an unmanned aerial vehicle (UAV) was used to detect and map surface discontinuities with displacements of a few centimeters, indicating the presence of initial geological deformations. The study found that sediments of alluvial fans are susceptible to various tectonic and exogenous deformational processes, and the interpretation of ultra-high resolution UAV images can help recognize low-amplitude brittle deformations at an early stage. UAV surveys are critical for discerning neotectonic activity and its related hazards over short observation periods.

Choosing a sample size allocation to strata based on trade-offs in precision when estimating accuracy and area of a rare class from a stratified sample

Stephen Stehman, John E. Wagner

Summary: This article investigates optimal sample allocation in stratified random sampling for estimation of accuracy and proportion of area in applications where the target class is rare. The study finds that precision of estimated accuracy has a stronger impact on sample allocation than estimation of proportion of area, and the trade-offs among these estimates become more pronounced as the target class becomes rarer. The results provide quantitative evidence to guide sample allocation decisions in specific applications.

Use of a new Tibetan Plateau network for permafrost to characterize satellite-based products errors: An application to soil moisture and freeze/ thaw

Jingyao Zheng, Tianjie Zhao, Haishen Lu, Defu Zou, Nemesio Rodriguez-Fernandez, Arnaud Mialon, Philippe Richaume, Jianshe Xiao, Jun Ma, Lei Fan, Peilin Song, Yonghua Zhu, Rui Li, Panpan Yao, Qingqing Yang, Shaojie Du, Zhen Wang, Zhiqing Peng, Yuyang Xiong, Zanpin Xing, Lin Zhao, Yann Kerr, Jiancheng Shi

Summary: Soil moisture and freeze/thaw (F/T) play a crucial role in water and heat exchanges at the land-atmosphere interface. This study reports the establishment of a wireless sensor network for soil moisture and temperature over the permafrost region of Tibetan Plateau. Satellite-based surface soil moisture (SSM) and F/T products were evaluated using ground-based measurements. The results show the reliability of L-band passive microwave SSM and F/T products, while existing F/T products display earlier freezing and later thawing, leading to unsatisfactory accuracy.
