The sandbank is a potential huge land resources, especially for land nervous regions, however, it has a very important realistic significance. So it becomes more important for sandbank shoreline's rapid monitoring, extraction and changing analysis. For the rapid extraction of sandbank shoreline of Jiangsu, China. Wavelet transform will be used first to process TM image. Then, on the basis of analyzing...
Quickly and accurately extract the water body information from remote sensing image is an important work in water pollution monitoring and LUCC research. In this paper, water body information of Yixing city in the west of Taihu Lake, China was extracted based on ALOS AVNIR-2 multispectral image, using the multi-level and multi-rule decision tree method. The image was acquired on 29 November 2007,...
From the perspective of semantic network model, this paper does research on the urban road extraction from high-resolution remote sensing images. First, we analyze spatial features and contextual information of road in high resolution remote sensing images. By using the method of regional segmentation edge detection, area filter and Hough transform methods respectively, we obtain the candidate nodes...
