    Yu Huaqi, Qi Xiaoping
    REMOTE SENSING FOR LAND & RESOURCES. 1999, 11 (3): 16-22.   DOI: 10.6046/gtzyyg.1999.03.05
    Abstract   HTML   PDF (579KB) ( 734 )

    Petroleum remote sensing is a very important branch of remote sensing technology. In this paper, the authors look back the grown up courses and the great achievements of petroleum remote sensing technology during the last twenty years. It is a process of growing up from nothing, from small to large, and the grown up courses of petrolem remote sensing passed through a process of building an enterprise through arduous effort, growing in strenght, and developing steadily. The authors also discuss the applications of petroleum remote sensing technology in petroleum research, petroleum engineering construction, environment monitoring. Finally, the authors prospect the prospects of petroleum remote sensing applications.

    REMOTE SENSING AND SCALE TRANSFERING OF LEVITY PARAMETERS ON EARTH SURFACE
    Zhang Renhua, Sun Xiaomin, Su Hongbo, Tang Xinzhai, Zhu Zhilin
    REMOTE SENSING FOR LAND & RESOURCES. 1999, 11 (3): 51-58.   DOI: 10.6046/gtzyyg.1999.03.11
    Abstract   HTML   PDF (1205KB) ( 1506 )

    The purpose of the paper is to clarify scientific significance of the remote sensing for obtaining levity parameters in time and space on the earth surface. First of all, Several regional imageries of the levity parameters, such as leaf area index, ground surface temperature and the net radiation were made using remote sensing data and the ecosystem network data. Secondly, measurements at the ecological stations were indicated in the imageries. Thirdly, averages and deviations for several different scale areas were made by using imaging processing. Fourthly, differences between the measurements at points and averages in the areas were pointed out. Finally, analyses the possible error when using measurements at points to express regional distribution. The analyses indicated the traditional expression of the regional averages for the parameters using single point measurements error beget very big error for leaf area index . There the leaf area index has extreme inhomogeneous distribution in space. The ground surface temperature takes second place. Meantime limitation of the remote sensing was also discussed. Effective and feasible way which express regional distribution well is combination between remote sensing method and point measurements。

    SHALLOW WATER DEPTH EXTRACTION AND CHART PRODUCTION FROM TM IMAGES IN NANSHA ISLANDS AND NEARBY SEA AREA
    Di Kaichang, Ding Qian, Chen Wei, Cao Wenyu
    REMOTE SENSING FOR LAND & RESOURCES. 1999, 11 (3): 59-64.   DOI: 10.6046/gtzyyg.1999.03.12
    Abstract   HTML   PDF (413KB) ( 1323 )

    This paper studies the model and techniques of extracting shallow water depth from TM images and image chart production in Nansha Islands and nearby sea area. On the basis of the conventional multi-band linear regression model, we develop a improved model by introducing a series of techniques including data pre-processing by group averaging, tidal correction, piecewise linear regression, data normalization, etc.. The improved model is more reasonable and accurate and suitable for large sea area. And we also present a set of techniques for remote sensing image chart production.

    Taking Miaoershan district in Guangxi Province of South China as an example, the characteristics and the processing techniques of the airborne hyperspectral data are discussed in detail. A series of programs for strip_removing, registration between bands, tangent correction illumination calibration and relative reflectance calibration has been developed. On the basis of software ENVI (the Environment for Visualizing Images), a field spectral library in the study area has been set up and a method for geometric corrections with satisfactory mosaic images has been developed. Great achievements in some aspects such as pure pixel extraction, spectral unmixing, interpretation, silicified zones and other alteration zones are successfully delineated and specific uranium prospecting areas are proposed.
