分析遥感影像不同类型波段在树种分类中的表现, 可为遥感数据光谱信息的深度挖掘提供基础信息。 本 研究以8波段Worldview鄄2影像为数据源, 将光谱波段分为传统波段和新增波段两种类型, 在室外调查的基础上 利用最大似然法对树种进行分类, 分析传统波段、 新增波段及完整波段在树种识别中的精度差异。 结果表明: 传统波段对树种分类的总体精度 (63郾3482%) 不及新增波段的 (67郾6696%...
The traditional fusion methods are based on the fact that the spectral ranges of the Panchromatic (PAN) and multispectral bands (MS) are almost overlapping. In this paper, we propose a new pan-sharpen...
WorldView-3, as a high-resolution commercial earth observation satellite, which is launched by Digital Global, provides panchromatic imagery of 0.31 m resolution. The positioning accuracy is les...
GeoRaySAR, an automated SAR simulator developed at DLR, identifies buildings in high resolution SAR data by utilizing geometric knowledge extracted from digital surface models (DSMs). Hitherto, the si...
The Optimal Band Ratio Analysis (OBRA) could be considered as an efficient technique for bathymetry from optical imagery due to its robustness on substrate variability. This point receives more attent...
Advances in geotechnologies and in remote sensing have improved analysis of urban environments. The new sensors are increasingly suited to urban studies, due to the enhancement in spatial, spectral an...
The latest breed of very high resolution (VHR) commercial satellites opens new possibilities for cartographic and remote sensing applications. In this way, object based image analysis (OBIA) approach ...
Greenhouse detection using remote sensing technologies is an important research area for yield estimation, sustainable development, urban and rural planning and management. An approach was developed i...
对地资源探索是遥感技术的追求目标,Worldview-1是高精度商业卫星之一,星下点分辨率为0.5 m。提出一种基于图像的Worldview-1全色波段仿真方法。以低空飞行的可见近红外图像为数据源,利用大气校正或经验线性法进行反射率反演得到地面反射率图;然后经过以下四个步骤:辐射传输模拟、光谱波段匹配、空间分辨率仿真和传感器调制传递函数MTF仿真,仿真出Worldview-1全色波段图像。通过以飞...
The use of rational functions has become a standard for very high-resolution satellite imagery (VHRSI). On the other hand, the overall geolocalization accuracy via direct georeferencing from on board ...
This paper validates the potentials of Worldview-3 satellite images in large scale topographic mapping, by choosing Worldview-3 along-track stereo-images of Yi Mountain area in Shandong province China...
This paper describes the investigations carried out at ETH Zurich on the very-high resolution optical satellite sensor WorldView-1. The dataset includes a stereopair acquired in November 2007 over Mo...
The geometric resolution of space images has been improved. With WorldView-1 and GeoEye-1 images taken from space with 0.5m ground sampling distance (GSD) are now available. The Bosphorus Engineerin...
The first part of this paper proposes a precise definition of what a worldview is, and why there is a necessity to have one. The second part suggests how to construct integrated scientific worldviews....
Is there such a thing as a philosophical method? It seems that there are as many philosophical methods as there are philosophies. A method is any procedure employed to achieve a certain aim. So, befor...
