Establishing an effective real-time monitoring and early warning system for glacier lake outburst floods (GLOFs) requires a full understanding of their occurrence mechanism. However, the harsh conditions hard-to-reach locations these glacial lakes limit detailed fieldwork, making satellite imagery critical tool monitoring. Lake Mercbacher, ice-dammed in central Tian Shan mountain range, poses significant threat downstream due to its relatively high frequency outbursts. In this study, we...
Against the background of rapid climate warming, frequent and severe flooding disasters significantly impact socio-economic development human life. In 2023, due to northward movement Typhoon Doksuri, extreme precipitation occurred in northern China, which resulted a massive flood event Haihe River basin. Seven detention basins (FDBs) North China were successfully implemented effectively alleviate downstream pressure. Leveraging all available Chinese satellite data, we monitored process...
利用高光谱地物光谱仪在巢湖进行了反射光谱测量和同步水质采样分析.在分析巢湖水体反射光谱特征的基础上,通过研究水体光谱反射率与叶绿素浓度之间的关系,利用反射率比值法和一阶微分法分别建立了叶绿素a的遥感定量模型.结果表明反射率比值R<sub>705nm</sub>/R<sub>680nm</sub>和 690nm反射率的一阶微分均与叶绿素a浓度有较好的相关性,且用反射率比值法估算叶绿素a效果较好.;Chaohu Lake is one of the biggest freshwater lakes China.This study was conducted to establish correlations between reflectance spectra and contents chlorophy ll-a in Chaohu Lake, which eutrophic status.Reflectance were measured during November, 2001 by using ASD FieldSpec HandHeld...
Major disasters typically impact large areas, cause considerable damages, and result in significant human economic losses. The timely accurate estimation of impacts damages is essential to better understand disaster conditions support emergency response operations. Geo-information drawn from various sources at multi spatial-temporal scales can be used for assessments through a synthesis hazard, exposure, post information based on pertinent approaches. Along with the increased availability...
The precisely and timely extraction of burned areas after forest fire plays an important role in reducing disaster losses, maintaining ecological balance protecting resources. In this article, we propose a method automatically extracting by using Gaofen-1 remote sensing images. Firstly, the geometric correction atmospheric are carried out WFV (Wide Field Viewer) images, then normalized vegetation index is calculated nearinfrared band red band. results, Otsu's used to set threshold value...
China is one of the countries most seriously affected by natural disasters in world. What's more important suffering many kinds which have wide range distribution, high frequency, regional strong seasonality, cause serious loss and present complicated disaster. Disaster event management includes whole process disaster response. Integrated Reduction Quick Service Platform can realize comprehensive prevention mitigation business oriented from satellite mission planning, data acquisition,...
Remote sensing is one of important methods on the agricultural drought monitoring for its long-term and wide-area observations. The detection soil moisture vegetation growth condition are two widely used remote that. However, because time lag in impact water deficit crop growth, it difficulty to indicate severity by once monitoring. It also cannot distinguish other negative such as low temperature or solar radiation. In this paper, joint use detections was applied management during summer...
Glacial hazards pose significant threats to millions globally, especially with rapid climate warming drawing increased attention. Understanding past glacial on both global and regional scales is crucial for early warning systems. This study quantified glacier lake changes the Tibetan Plateau over recent decades analyzed spatial temporal distribution of major disasters. It also focused lakes that have experienced out-burst events by reconstructing long-term data 48 lakes. Key findings...
Flood disasters are frequent, sudden, and have significant chain effects, seriously damaging infrastructure. Remote sensing images provide a means for timely flood emergency monitoring. When floods occur, management agencies need to respond quickly assess the damage. However, manual evaluation takes amount of time; in current, commercial applications, post-disaster vector range is used directly overlay land cover data. On one hand, data not updated time, resulting misjudgment disaster...
The Mw 7.4 Hualien earthquake, occurred in the northernmost Longitudinal Valley on 3 April 2024 is strongest Taiwan 25 years. This study investigated fault geometry, slip distribution, and rupture process of event, using teleseismic, regional strong-motion, near-field geodetic observations as constraints, along with relocated aftershocks their focal mechanisms for auxiliary validation additional constraints. Subsequently, preferred model determined this 49 historical models collected or...
Full-polarimetric SAR image is very useful for the landslide monitoring especially in well vegetation-covered mountainous region. GaoFen-3 (GF-3) first civil C-band fully polarimetric satellite China. In order to test ability of GF-3 full-polarimetric data on monitoring, 2 cases southwestern part China 2017 and 4 decomposition methods (Pauli, Krogager, Freeman, H-α/A) were selected. It was found that had a good performance that. The scattering mode changed from volume surface by four which...
Glaciers are sensitive indicators of climate change, and investigation their dynamics is crucial for ensuring regional ecological security as well disaster prevention mitigation measures. Based on Landsat Thematic Mapper (TM)/Enhanced Plus (ETM+)/Operational Land Imager (OLI) imagery, the outlines length glaciers in West Kunlun Main Peak Area (WKMPA) during 2000–2020 were obtained by combining a band ratio method with manual interpretation an automatic extraction glacier centerline,...
Satellite remote sensing can provide repeat and detail observations, which has played an important role on the disaster management. Different with existing satellites, GF-4, works geosynchronous orbit carry a camera 50 meter spatial resolution in visible NIR bands, give continuous earth observation. It is highest among civil satellite orbit, have 4 operation mode: general, continuous, regional maneuvering, very suitable for In this paper, based those characteristics of capacity management...
Tornado disaster is not the main natural disasters in China, but it could cause serious casualties and economic losses. As a means of large-scale dynamic monitoring, remote sensing monitor loss housing facility agriculture tornado disaster, reconstruction infrastructure such as post-disaster houses.
