To meet the actual needs of refined land-cover information in poverty-stricken areas' ecological environment assessment and resource survey, this paper studies the technology and application of accurate land-cover classification based on the high-resolution satellite images. This article focuses on the technologies of high-resolution image segmentation using the mean shift algorithm, multiple feature extraction and analysis, automatic object-sample selection, and supervised classification. Then, we give a complete realization of the streamlined object-based land-cover classification by lining up the above technologies. Finally, taking Qianjiang district of Chongqing city as an example, we carry out a land cover information extraction experiment in its poverty-stricken areas. The experimental results show that the accurate and detailed land-cover maps can be obtained using the provided technology. The meticulous and reliable land-cover information can promptly provide a base-data-support for the eco-environmental assessment and carbon accounting applications in the poverty-stricken areas. |
