A COMPARATIVE STUDY OF LAND SURFACE TEMPERATURE WITH DIFFERENT INDICES ON HETEROGENEOUS LAND COVER USING LANDSAT 8 DATA
LST Landsat 8 NDBI NDSI NDVI NDWI Land Cover
2018/11/19
The temperature rise in urban areas has become a major environmental concern. Hence, the study of Land surface temperature (LST) in urban areas is important to understand the behaviour of different la...
EXTRACTION OF BLUE ICE AREA USING ALBEDO VALUE DERIVED FROM LANDSAT-8 SATELLITE DATA
Blue Ice Landsat-8 Albedo Polar record Glacier Image Processing
2018/11/19
Blue Ice Areas (BIAs) or bare ice areas are zones of glacier where surface mass balance is negative, sublimation forms the major ablation process and surface albedo is relatively small. Exceptionally ...
MAPPING SPATIOTEMPORAL DISTRIBUTION OF MANGROVES IN MAFIA ISLAND IN TANZANIA USING LANDSAT IMAGERY
Mapping Mangroves Satellite Image Landsat Mafia Island
2018/7/11
Mangroves are important for survival of coastal communities as they provide ecosystem services that support coastal population and their livelihoods. Most coastal communities largely depend on ecosyst...
RADIOMETRIC CROSS-CALIBRATION OF GAOFEN-1 WFV CAMERAS WITH LANDSAT-8 OLI AND MODIS SENSORS BASED ON RADIATION AND GEOMETRY MATCHING
Radiometric Cross-Calibration, Geometry Matching, Radiative Transfer Model, Water Vapor Effects, Synchronization Verification
2018/4/30
Cross-calibration has the advantages of high precision, low resource requirements and simple implementation. It has been widely used in recent years. The four wide-field-of-view (WFV) cameras on-board...

新型Landsat 8卫星影像的反射率和地表温度反演
影像处理 地表温度 反射率 遥感
2015/3/20
Landsat 8卫星自2013年2月发射以来,其影像的定标参数经过了不断调整和完善,针对Landsat 8开发的各种算法也相继问世.本文采用最新的参数、算法和引入COST算法建立的大气校正模型,对Landsat 8多光谱和热红外波段进行了处理,反演出它们的反射率和地表温度,并与同日的Landsat 7数据和实测地表温度数据进行了对比.结果表明,现有Landsat 8多光谱数据的定标参数和大气顶部...
Monitoring of Net Primary Production in California Rangelands Using Landsat and MODIS Satellite Remote Sensing
Grasslands MODIS Landsat California Net Primary Production
2012/6/25
In this study, we present results from the CASA (Carnegie-Ames-Stanford Approach) model to estimate net primary production (NPP) in grasslands under different management (ranching versus unmanaged) on...
基于Landsat/TM影像提取太湖CDOM浓度空间分布
CDOM 遥感反演 Landsat/TM 太湖
2011/1/1
在湖泊生态系统中，CDOM(colored dissolved organic matter)是营养物质的重要来源，也是碳循环过程的主要物质组成。作者在2003年10月27日—28日太湖水质实验数据的基础上，研究与探讨了从Landsat/TM影像中提取太湖CDOM浓度分布状况的方法。通过研究可知，利用CDOM在TM1波段的强吸收特性，对应的光谱曲线呈现一个吸收波谷;以TM1波段反射率为遥感参数，结...
20世纪末以来，多种新型传感器的升空使得不同传感器之间的互为比较成为一个新的研究热点，但是ASTER和Landsat-7 ETM+传感器多光谱数据之间的全面对比在国内外尚未报道, 为此，该文对ASTER和Landsat-7 ETM+传感器影像数据进行了对比互补研究。文章从传感器的轨道特征、扫描方式、光谱范围和光谱响应特征等方面对二者进行机理上的分析和对比。在此基础上，基于3对同步过空的影像对和大面...
该文建立了反向传播人工神经网络 (Back Propagation Artificial Neural Network, BP-ANN)和遗传算法 (Genetic Algorithm, GA)的BP-ANN/GA混合算法。利用GA算法的全局优化能力优化BP-ANN的初始权值，克服了传统BP-ANN收敛速度慢，容易陷入局部最小的缺点。BP-ANN/GA混合算法对Landsat ETM+4, 5, ...
