例句與用法

1. Quickbird imagery for crop pattern mapping
   高精度作物分布圖制作
2. 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區(qū)的ikonos 、 quickbird 、 spot 、 landsattm / etm +等多種多光譜/全色衛(wèi)星遙感圖像的融合實(shí)驗(yàn),并與其它一些典型的圖像融合算法進(jìn)行了比較分析。
3. 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 +圖像上對(duì)滑坡發(fā)育的地質(zhì)背景進(jìn)行解譯，提取了地形、地層巖性、地質(zhì)構(gòu)造等信息，在quickbird影像上詳細(xì)地圈定了滑坡災(zāi)害體的實(shí)體位置及發(fā)育范圍，通過(guò)對(duì)所提取信息進(jìn)行分析，本文認(rèn)為，奉節(jié)縣地質(zhì)構(gòu)造復(fù)雜，巖性破碎；峽谷段巖層穩(wěn)定性較好；南岸部分地段為順向巖層分布區(qū)，人類工程活動(dòng)容易誘發(fā)順層滑坡，蓄水后庫(kù)岸整體穩(wěn)定性下降。
4. 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
   采用遙感技術(shù)，可以突破傳統(tǒng)調(diào)查方法的限制，發(fā)揮其宏觀、綜合、直觀、快速的特點(diǎn)，取得更好的效果。論文選取目前應(yīng)用最廣的陸地衛(wèi)星最新系列l(wèi)andsat - 7etm +數(shù)據(jù)和空間分辨率最高的商業(yè)衛(wèi)星quickbird數(shù)據(jù)作為主要的數(shù)據(jù)源，根據(jù)數(shù)據(jù)的特點(diǎn)及滑坡災(zāi)害應(yīng)用特征，對(duì)quickbird遙感數(shù)據(jù)則基于1 ： 10000dem進(jìn)行了正射校正，對(duì)etm +遙感數(shù)據(jù)進(jìn)行了波段優(yōu)選，選取了753作為最佳組合波段；圖像增強(qiáng)，通過(guò)各種增強(qiáng)處理方法的效果對(duì)比，選擇主成分分析法對(duì)圖像進(jìn)行增強(qiáng)；幾何精校正，糾正圖像的幾何變形；影像融合，主要選取了效果較好的his空間變換融合和分辨率融合，得到的圖像既具有較高的光譜分辨率，同時(shí)也具有較高的空間分辨率。經(jīng)過(guò)上述數(shù)字處理，較好地改善了圖像的視覺(jué)效果，提高了圖像解譯的精度。
