Hyperspectral remotely sensed image provides very informative information for a wide range of applications that relate to landcover classification. Many studies have shown that the spectral-spatial information is well effective for hyperspectral image (HSI) classification. However, for the spatial based methods, it may sometimes encounter many difficulties in obtaining the spatial prior of different...
Jiangsu has the most abundant tidal flat resources among China’s coastal provinces. To ease the conflict between the growing population and shrinking usable land and to promote regional sustainable development, large-scale coastal reclamation development activities have been performed in Jiangsu Province since 1949. The present study has integrated multi-source remote sensing images during 1974 to...
Nowadays China has speeded up urbanization, urban land use occurred in areas of significant change. In order to obtain land cover information speedily and correctly, many methods from data mining are used to classify the remote sensing image. In recent years, using decision trees (DTs) to classify remotely sensed data has increased, due to the algorithm running fast and making no statistical assumptions...
Rapid urban expansion in the surrounding area is a major reason of ecological environment deterioration. This research adopted SLEUTH model and imported the result of ecological environment analysis as the excluded layer by building multi-factor comprehensive decision model, therefore, realized a loose couple of urban growth model and ecological environment analysis. The result indicates that this...
A model was developed using remote sensing and geographic information system technologies for habitat identification of Oncomelania hupensis, the intermediate host snail of Schistosoma japonicum, in the Poyang Lake area, China. In a first step, two multi-temporal Landsat TM 5 satellite images, one from the wet and the second from the dry season, were visually classified into different land-use types...
