This paper presents a brief synthesis of the information obtainable from remote sensing data and how they can be used to design the land degradation assessment model. The use of the Modified Soil Adjusted Vegetation Index (MSAVI), Soil Wetness Index (SWI) and Land use derived from the Landsat Thematic Mapper (TM) were derived for detection and assessment of land degradation in Guyuan County, Hebei...
Soil erosion is a serious geo-environmental issue causing land degradation in China. Developing new techniques based on remote sensing data to assess soil erosion will assist in the comprehensive treatment of environment and the sustainable management of soil resources. In this paper, land cover and Normalized Difference Vegetation Index (NDVI) were derived from Landsat Thematic Mapper (TM) images...
Based on the feature of CCD image forming, the internal principle of image forming is analyzed, and the loss of charge transfer is calculated by the Shockley - Read - Hall equation, in which the distribution function between the charge transfer is reconstructed. Rational polynomial interpolation algorithm is used to determine the unknown pixel points for the adjacent pixels that do not overcome the...
Chang'e-1 Microwave Sounder (CELMS) is a main payload of Chang'e-1 Moon Orbit Satellite in the first stage of China Lunar Probe. CELMS is a four-frequency microwave radiometer with frequencies 3GHz, 7.8GHz, 19.35GHz and 37GHz. During the one year and four months' working in lunar orbit, it got huge scientific data covering full moon surface and obtained the world first global lunar microwave emission...
Soil erosion is one of the major serious geo-environmental issues causing land degradation in China. Developing new remote sensing techniques to analyze the change of soil erosion will assist in the comprehensive treatment of environment and the sustainable management of soil resources. In this study we derived land cover and NDVI from TM 5 images, to assess the soil erosion with DEM. These techniques...
China has launched a microwave radiometer (MWS) to the Moon orbit to detect regolith information of the lunar surface. It is the first time that humankind directly applies sensed brightness temperature to investigate the lunar surface information by passive microwave sensor on lunar orbit. Therefore, it is necessary to set up theoretical models to describe lunar surface microwave transfer process,...
It was the first time that China launched a microwave radiometer to orbit the Moon in order to measure soil information of the lunar surface. In this paper, we will investigate a microwave radiative transfer model for simulating and retrieving lunar regolith depths. We solve numerically the integral equation of the lunar soil by dividing the soil into many layers, and at each layer, emission, multi-reflection,...
