- Abstract
With the acceleration of the urbanization process, the spatial layout of cities is constantly changing, which also affects the functional organization of the cities. Based on the imaging technology of scanning probe microscope, the high spatial resolution hyperspectral remote sensing is selected as technical support to investigate the urban spatial geographic data information and effectively classify the features, thereby providing valuable data support for urban land-use and urban planning management. By taking the atomic force microscope as the primary equipment, the system structure and imaging principles of the scanning probe microscope are introduced. Then, the applications of high-resolution hyperspectral remote sensing technology, especially in the classification of urban targets, are discussed in detail. Eventually, the combination of spectral and spatial features extracted from hyperspectral images is proposed, and the classification accuracy is expected to be further improved. Based on the hyperspectral remote sensing data, the spectral characteristics of urban targets can be studied, which can be applied to the fields of information extraction, regional classification, and environmental detection of urban targets. The hyperspectral remote sensing data not only can identify and monitor various buildings, roads, water bodies, bare soils, plants, and other targets in the cities easily and quickly but also can extract the dynamic change information of urban targets in real-time, providing accurate data support for urban planning and management. By combining the spectral and spatial features directly into a spatial-spectral joint feature, the accuracy is improved relative to the spectral and spatial features.
