Examples
- Quickbird imagery for crop pattern mapping
高精度作物分布图制作 - The new algorithm has been tested on various multispectral and panchromatic satellite remote sensing images on ikonos , quickbird , spot , landsat tm / etm + for different areas , and has been compared with some other typical image fusion methods
新融合算法被用于不同地区的ikonos 、 quickbird 、 spot 、 landsattm / etm +等多种多光谱/全色卫星遥感图像的融合实验,并与其它一些典型的图像融合算法进行了比较分析。 - At last , the paper interprets the geological background of the forming of landslides , and reveals the landform , stratum , lithology and geologic structure based on the etm + image . and also , the paper interprets the location and distribution of the specific disaster bodies based on the quickbird image . through the analysis of the extracted information , the paper considers : the geologic structure of fengjie county is complex , and lithology is crashed ; the terrane in the canyon segment is fairly stable ; the terrane in some segments of the southern bank will be less stable after the water is stored , because the rock is in the same direction and is apt to slip with human project
最后在etm +图像上对滑坡发育的地质背景进行解译，提取了地形、地层岩性、地质构造等信息，在quickbird影像上详细地圈定了滑坡灾害体的实体位置及发育范围，通过对所提取信息进行分析，本文认为，奉节县地质构造复杂，岩性破碎；峡谷段岩层稳定性较好；南岸部分地段为顺向岩层分布区，人类工程活动容易诱发顺层滑坡，蓄水后库岸整体稳定性下降。 - Investigation using remote sensing ( rs ) technology can breakthrough the limits of traditional methods , make full use of its capability of integration , visualization , rapidity and vast - dimensions analysis , and get better results the paper takes the up - to - date landsat - 7 etm + data , which is the most widely used , and quickbird data , which has the highest resolution nowadays , and according the features of the data and landslides , processes the quickbird data with 1 : 10 000 dem orthophoto correction and the landsat - 7 etm + data as follows : ( 1 ) selecting optimal spectrum band : selects 753 bands as the optimal bands ; ( 2 ) image intensifying : selects the principle components processing method on the basis of comparing several image intensifying methods ; ( 3 ) rigour geometric direction : corrects the geometric distortion of the map ; ( 4 ) image fusion : mainly takes his space transform fusion and resolution fusion method , and acquires maps with higher spectrum resolution as well as space resolution . after that , the visual effect of the image has been enhanced , and the interpretation precision
采用遥感技术，可以突破传统调查方法的限制，发挥其宏观、综合、直观、快速的特点，取得更好的效果。论文选取目前应用最广的陆地卫星最新系列landsat - 7etm +数据和空间分辨率最高的商业卫星quickbird数据作为主要的数据源，根据数据的特点及滑坡灾害应用特征，对quickbird遥感数据则基于1 ： 10000dem进行了正射校正，对etm +遥感数据进行了波段优选，选取了753作为最佳组合波段；图像增强，通过各种增强处理方法的效果对比，选择主成分分析法对图像进行增强；几何精校正，纠正图像的几何变形；影像融合，主要选取了效果较好的his空间变换融合和分辨率融合，得到的图像既具有较高的光谱分辨率，同时也具有较高的空间分辨率。经过上述数字处理，较好地改善了图像的视觉效果，提高了图像解译的精度。
