Applications of Spot-5 Imagery in Surveying and Mapping of West Regions in China

چکیده
During the past 50 years, there are no topographic maps at scaled of 1:50,000 in the West Regions of China. Beside the extremely adverse environmental condition of the regions, the poor surveying and mapping technology is an important factor to cause the situation. This kind of present condition limited the Development of the West Regions and embarrassed the economic and social sustainable development of China. For solve this kind of predicament, the project of Surveying and Mapping of the West Regions in China was launched in 2006 and Remote Sensing techniques are applied to the project. SPOT-5 imagery is one of important data sources of the project. The paper discusses the applications of SPOT-5 images in Surveying and Mapping of West Regions in China. Within the SPOT constellation, SPOT-5 is the most innovative satellite. SPOT-5 HRS, HRG and multi-spectral images are applied in the project of Surveying and Mapping of West Regions in China. SPOT-5 images orientation is studied firstly. Secondly, mapping from SPOT-5 HRS stereo image pairs in seamless mapping system is also given. Thirdly, DEM generation by two means are introduced. Finally, DOM from SPOT-5 HRG and multispectral imageries are also introduced. Email: [email protected] Tel: 13607138724

Hyperspectral remote sensing records reflectance or emittance data in a large sum of contiguous and narrow spectral bands, and thus has many information in detecting and mapping the mineral zones. On the other hand, the geological and geophysical data gives us some other fruitful information about the physical characteristics of soil and minerals that have been recorded from the surface. ...

Successful target detection, especially if there is a similarity between the target and the background area, always is a noticeable issue in remote sensing studies. Because of the spectral behavior similarity to the other phenomena and spatial distribution of these units, the mapping of wind erosion units is difficult. Thus, this study attempts to detect the favorable areas by using matched fil...
