  landsat
Based on three scenes of Landsat 5 Thematic Mapper (TM) satellite images acquired on June 26, 1994, 12 land cover types were identified by the supervised classification techniques.
      
The study was based on five periods of land cover maps derived from remotely sensed data: Landsat MSS for 1978, Landsat TM for 1984, 1992, 1996 and 2001, and the digital elevation model (DEM) derived from 1:250,000 topographic map.
      
The system has been tested successfully with SPOT MS and LANDSAT images.
      
The Landsat 5 TM data were used to classify the forest landscapes through RS digital cartography, and then, the landscape characteristics and landscape pattern were analyzed quantificationally.

In this paper, Karhunen-Loeve transformation and the R-Factor Analysis have been used in compression-processing the multi-spectrum data on the land satellite Computer Compatible Tape (CCT).

With the aid of electronic computers, data compression processing is an important technique used for recognizing the pattern of remote sensing images. In this paper, Karhunen-Loeve transformation and the R-Factor Analysis have been used in compression-processing the multi-spectrum data on the land satellite Computer Compatible Tape (CCT). As a result, with about 99% of the information being kept, the characteristic quantities can be compressed from four dimensions into two dimensions, so that a picture with clusters of dots can be made on a sheet of paper for recognizing and defining the objects.

数据压缩处理是利用电子计算机,对遥感图象进行模式识别的一项重要技术。本文应用Karhunen—Love变换与R型因子分析,对陆地卫星计算机兼容磁带的多光谱数据作了压缩处理。结果,在基本保持遥感信息量的情况下,使特征量由四维压缩成二维,因而就能在座标纸上作出点聚图,对事物加以识别与区分。从计算结果看来,R型因子分析比Karhunen—Loève变换似更理想。

By the use of the digital data of films of the second...

The launching of land satellites makes it possible to make a quick and accurate study of land cover of a watershed, which is of great significance in hydrography.The present article takes Da-Wen River in the lower reaches of the Huang He River as an example, and selects seven kinds of typical land cover, mountains covered with dense forests, mountains covered with sparse forests, hills covered with grass and bush, hilly fields, plain fields, water and city. By the use of the digital data of films of the second land satellite of Oct.31, 1975 in 4 bands and the digital data of photograph of the third land satellite of April 1, 1978, MSS7, land cover of a watershed was analysed in a quantitative way and its was result compared with that of visual interpretation.The analysis is as follows.1. The order of photograph, in terms of ability of identifying objects on the land by land satellites, is MSS5, MSS6, MSS7 and MSS4. The order of quantitative analysis is MSS5, MSS7, MSS6 and MSS4. but any single band can't recognize all the selected objects on the land.2. Two dimensional space consisting of MSS5 and MSS7 is the best space for identifying land cover of a watershed.3. Colour photograph composed of four bands is capable of identifying objects on land-five out of eight objects.4. By the use of chart 7 and discrimination analysis approach, land cover of a watershed can be recognized and analysed.The quantitative approach with non-computer identification of objects on the land is fit for the study of kinds of samples within a certain range.

陆地卫星资料的应用研究中,先对少量样本进行分析,然后上计算机处理,可以减少研究工作中的浪费与盲目性。本文以黄河下游大汶河为例,利用陆地卫星多谱段数据,对流域的稠密森林山地、稀疏林山地、草被灌丛山地、丘陵农田、平原农田、水体、城市等地物进行数值分析识别,并与常规目视解释作了比较。通过分析比较认为:陆地卫星单波段识别地物的功能,若以优劣评阶,影象的次序为:MSS5、MSS6、MSS7、MSS4,数值分析的次序为:MSS5、MSS7、MSS6、MSS4,但任一单波段都不能识别所选择的全部地物;由MSS5与MSS7构成的二维空间是识别流域地物的最佳判别空间;四个波段合成的彩色片可识别8类地物中的5种,具有良好的识别功能;利用MSS7~MSS5灰阶值点聚图及判别分析方法,可对流域地物进行识别分析,这种非计算机识别地物的数值法,适合于研究指定范围内样本的地物类型。

By carefully interpreting the Xizang Landsat imageries, we have discovered a series of active faulting belts and recent basins. Moreover, magmatism and volcanic and geo thermal activities may come very intensive in Xizang. We have applied the Landsat image to making the seismo-tectonic map of Xizang. It shows that the Xizang plateau has three main structural types. The south Xizang area consists of many closely parallel and rectilinear lineaments which indicate an intensively compressive deformation; the middle...

By carefully interpreting the Xizang Landsat imageries, we have discovered a series of active faulting belts and recent basins. Moreover, magmatism and volcanic and geo thermal activities may come very intensive in Xizang. We have applied the Landsat image to making the seismo-tectonic map of Xizang. It shows that the Xizang plateau has three main structural types. The south Xizang area consists of many closely parallel and rectilinear lineaments which indicate an intensively compressive deformation; the middle Xizang area presents continually lenticular-like structures which show a plastic deformation; and the Qiangtang plateau possesses conjugated fracture deformation. These properties determine the seismic activities in the Xizang region and the three seismic areas can be classified.There have been more than 284 earthquakes with magnitude above 5 since 1870. We have subdivided the seismic events occuring during 20 th century into three periods, each extending about 30 years. Now the third period is going to come to an end.Finally we point out that earthquake frequency and intensity in Xizang are related to the collision of the India-Eurasia plate.

陆地卫星影象表明西藏地区存在一系列活动断裂带,晚第三纪以来的新生盆地和火山活动都十分强烈。从卫星照片中的线性构造及其组合特征分析,西藏高原具有三种不同的构造组合,雅鲁藏布江以南多为近东西向线性构造,为强烈挤压的形变特征,中部多为连续分布的透镜状构造,反映了地壳物质塑性流动的形变特征,羌塘高原则为共轭破裂的形变特征。这些特征客观地反映了西藏高原各块体之间的力学性质和介质条件的差异,也控制了西藏地区的地震活动性。
