      摘要:This article introduce procedures and methods of using large scale (1:5,000) color infrared transparency to inventory the damaged forests by an example in West Germany; summarize the interpretation keys of identifying tree species and injury status of forest trees on color infrared aerial photos; analyze the stress degree to forest health conditions by factors such as species, ages and elevation. Finally, precision of the inventory are listed. Results have already demonstrated that methods of applying color infrared photos to assess the injury degree to forest trees caused by air pollution, disease and insects, natural disaster can rapidly provide information with higher precision which is needed during the planning process of making sound forest management plans.

      摘要:By using the data of the landsat and with the help of computer image processing method, the information of shallow sea’s configuration and terrain are obtained in the areas of Chang Dao Island (Southern Bohai Strait), Ming Jian, Ou Jian and Pearl river mouth. In this paper, the auther discusses the characteristics of under-water terrain and the module of picking up water depth message. To obtain the better result, the multiseaonal and multispectral data are needed to pick up the information. It can be seen that the application of satellite remote sensing and image processing technology is one of the method of shallow sea investigation, and it’s a useful supplement for ordinary investigation, especially for the investigation in the changeable and dangerous oceanic areas. Also, its applications in sea shore planning, developing and managing such as environmental monitoring and evaluating for acquatic culture in bay.

      摘要:The large are of glacial erosion landform is discovered by the interpretation on large scale white-black airphotos in the eastern side of the southern segment of the Taihang mountain. 3 to 4 glacial epochs of landform of glacier erosion are distinguished. The glaciers of first and second epoch are valley-piedmont glacier. Other landforms are cirque, hanging valley, firn-basin and trough, etc. The glacial stage, its distribution tyge and characteristic of glacier are described in this paper. This work provids new evidences for futher researching the glacier movement in quaternary period in this area.

      摘要:A new method based on HOUGH transform for analyzing ocean wave from SEAS AT SAR image is presented here. This method takes the way which human vision takes to analysis nature texture image, after extracting the peak area from the SEASAT SAR image with CFCM classification method, we use random-go model to filter the classified image in order to obtain the global direction information of sea wave in the whole image. Then, according to this information, a directional tracking algorithm is used to extract the line group that represent sea wave peak line, finally, the extracted wave peak line group image is mapped into HOUGH transform domain. Statistic and analysis are undergone then to obtain the precise wave length and direction. Because it takes a way similar to human vision to analysis nature texture image, this new method gives an expected good performance. Experiment result is also presented here.

      摘要:On the basis of application of aerial remote sensing information to erosion environmental systematic mapping of valley and gully area on loess plateau, an extensive study on loess erosion environment changes has been made in this paper. By using the different period aerial-photos of Wang Jia Gou, a small basin, which located in Li Shi county, Shanxi province, and by using the advanced geographical information system software ARc/INFO system, we have compiled the erosion environmental systematic maps of different periods and of different types: multiple factors erosion map, erosion amount distribution map, basin’s valley and gully shape change map, average erosion developing speed map and basin multiple management evaluation map. On the basis of above works, we have made an analysis of erosion situation and environment changes in this small basin in different period by using environmental dynamic analysis method. Many-impacts, especially, the human impacts has been emphasized in the erosion environmental analysis.The results of this work has provided a scientific basis for multiple management for small basin on Loess plateau.

      摘要:According to the spectral characteristics of different geobodies, and using principal component analysis, information multiplex and multidisciplinary analysis method, a good result of mineralized information extraction was given in this paper, with FIMS flight strip in Tie-muerte of North Xinjiang.The yellow abnormal color tone was show en in the mineralized feature information of FIMS flight strip of the region in image processing result. It reflected on mineralized feature with lower content of silica and higher f erri-ferrous content in polymetalic mineralization belt. Yellow abnormal color tone in form of lumps showed the distribution of gasson, magnetite and skarn on exposing surface. According to the field examination, the distribution section of yellow color tone is in agreement with the mineralized area on the spot surface.There are four steps of multidisciplinary analysis for extracting the feature information of remote sensing, which are independent of each other and also related to each other. The four steps include: The analysis of essential feature information, image processing, verification analysis and mechanism explaination. In fact, only by multidisciplinary analysis, could the inherent law of feature information be revealed and the feature information extracted be made into a good practical value one.

      摘要:The analysis on soil spectral data obtained from the different area of our country shows that exists a soil spectral line in 2-dimension space or multidimension space, but it is not a strictly straight line, it is a belt with certain width. It is not suitable for vegetation analysis with a united soil spectral line in the whole country. The influence of different soil spectral line on plant canopy and greenness assessment was discussed. In addition, the results and physical significance of the principal component analysis on the soil spectral reflectance were described.

      摘要:The off-line working CCT formatter for the airborne scanner was successfully developed according to the characteristics of the airbone scanner and the requirements of the remote sensing users. Its principal functions are:(1) To transform the multispectral remote sensing information to computer compatible tape (CCT) from analogue high density tape.(2) To read out CCT data for quickly displaying or hardcopy of the image.(3) Rapidly to check up and locate given target in the subarea.This paper describes the design features of the CCT formatter hardware and software in detail. The CCT data format and some results of application are shown. The CCT formatter is not only one of the main fittings of the scanner, but also suitable for those digital image processing systems which deals with processing a large number of CCT data.
