First, the Landsat 8 OLI remote sensing image of Chongyang County is geometrically and radiometrically corrected using ENVI software to obtain high-quality remote sensing data. Then, using the object-oriented concept, the land use area is divided into multiple object layers, and an object-oriented land use information extraction model is established. In this model, based on the spatial position and attribute information of each object, combined with expert knowledge and rules, multi-level feature extraction and classification are carried out, and accurate land use type information is finally obtained. The experimental results show that the object-oriented land use information extraction method proposed in this paper has high accuracy and efficiency and can be applied to large-scale land use information extraction.精品文档---下载后可任意编辑Keywords: object-oriented; land use; information extraction; remote sensing image; feature extraction; classification
