Surface condition in the southern Taklamakan desert around hotien oases area
Abstract
Making use of the image data of high resolution panchromatic band together with other bands of Landsat -7 / ETM+ and SPOT/ HRV the surface condition around Hotien Oasis in the southern Taklamakan Desert are clarified. Through the comparison with MODIS data the effects of the spatial resolution on land use classification is made. An attempt is made to find the geometrical feature of sand dunes in this area based on the image data acquired during low sun elevation angle since the sand dunes are clearly shown through shadow effects. It is found that the average spacing of sand dunes is around 159m with standard deviation of around 44m. The height is less than 60 m.
