发布时间：2021-06-10 - 摘要：Global eco-environment and renewable natural resources Change very quickly, which is caused by human activity and exploitation in large scale. Monitoring of these Changes is a new research field of remote sensing application.This paper described a experiment study of remote sensing systematic analysis on natural resource and environment Change monitoring. Main methods concern changed factor extraction through the brightness statistics, ratio and texture analysis; matching multi-temporal remote sensing data, normalized difference comparison, "brightness" and "greenness" difference analysis of principal components method by using image processing system; updating renewable natural resources changed map through overlaying or partly revising multi-temporal maps by using geographical information system; establishing mathematic model, such as: variable correlation regional regression and tendency surface analysis etc., for researching renewable natural resource change law.

发布时间：2021-06-10 - 摘要：This paper reviews the history on developing airborne geological exploration and remote sensing technology as well as their present situation during last thirty years in China and enumerates a lot of main achivement and progress in advancing and substantiating geological theory, accelerating the regional geological exploration, promoting the reconnaissance survey of mineral resources, extending the prospect of geological resources, improving the survey work of hydrogeology, engineering geology, environmental geology, urban geology and disaster geology. The theory, methodology and technology in geological remote sensing application is developed obviously.According to the developing trend of remote sensing technology and geological theory, the prospect for geological remote sensing development is proposed. Recent achivement is tracked and the theory of geology is renewed. The pontential of remote sensing is developed further.Strive for making a more contributions to the theory of geology exploration of mineral resources, environmental geology and so on.

发布时间：2021-06-10 - 摘要：This paper describes the application of the optical and digital image enhancement processing to the multiband satellite remote sensing images and "CCT". By this method, the hidden structural information under water and Quaternary System in the coal district of South Four-Lake in Shandong Province, P.R.C. is extracted. The main fracture framework is interpreted and the hidden uplifts, depression, folds, igneous rock and their distributive ranges are pointed out. At the same time, the valuable data for the coalfield prospecting and opening are provided.

发布时间：2021-06-10 - 摘要：This paper deals with mapping abilities of Spacelab images （MC, Metric Camera）, and its geo-applications. The 1:100000 and 1:200000 scale topographic maps and orthophotomap had been made from MC stereo-image, the results show that the high resolution MC images surely could meet the national standard at the scale of 1:100000 either for planimetric accuracy or for height-measuring, and could be used for revising map at scale of 1:50000.The digital combination of digitized MC image and Landsat MSS in both spatial resolution and spectral characteristics were improved and it has some advantages for land use surveying and other geo-applications. The ground checking shows that the interpretation accuracy of land-use types were improved from 7% to 20% comparing with original Landsat MSS and MC images.

发布时间：2021-06-10 - 摘要：The classical analysis technique for ocean wave length and direction is the spectrum analysis. In this paper, A new texture analysis technique for ocean wave image performed in the spatial domain directly is presented. For every processing window, based upon the distribution of local extremes and the grey level co-occurrence matrix, the texture measures to discriminate the different kinds of ocean wave lengths and directions are constructed. Finally, the information of ocean wave lengths and directions is extracted.

发布时间：2021-06-10 - 摘要：One of the image pre-processing tasks in the Remote Sensing Satellite Ground Station is the Systematic Correction Processing which may remove almost all the distortions inside the scene. However, the location accuracy is still rough and may probably reach hundred meters or kilometers. A recursive algorithm based on the Kalman Filter rather than the Batch Processing Algorithm using a few number of Ground Control Points will be used to enhance the location accuracy. Moreover, the ephemeric data and the attitude data will also be updated. In a single scene processing, 8 or 9 Control Points will be sufficient to reach the good result. In the continual multi-scene processing of a path, this algorithm may be propagated to predict the locations or the ephemeric and attitude data of the next scenes, in which the Control Point may be not available.In the section 2 of this paper, the recursive algorithm and the coefficients of the Transition Matrix and the Measurement Matrix in the Kalman Filter equations will be derived. The results of the simulation experiments including 3 Figures and 2 tables will be presented in the section 3. The section 4 has some discussions about the convergence and the advantages of this algorithm. Finally, 6 references will be given for the convenience in the future discussions.
