基于高分辨率多光谱遥感数据的城市森林反射率真实性检验

Authenticity Testing of Urban Forest Reflectivity Based on High Resolution Multispectral Remote Sensing Data

城市森林资源信息对城市可持续发展有重要影响。为了满足城市森林资源精细化管理的需求,不断拓展国产高分辨遥感卫星的应用范围,需对其数据质量、数据规格和数据产品特点进一步的研究,进而应用于城市森林资源监测中。本文采用目前国际上正在开展的无场地定标技术,与定标精度比较高的landsat-8 OLI数据对高分1号8米的pms多光谱数据进行交叉定标,对国产高分辨率多光谱遥感数据的城市森林反射率进行真实性检验研究。

Urban forest resources information has an important impact on urban sustainable development.In this paper,the authenticity of urban forest reflectance is tested and analyzed by using the domestic high-resolution satellite GF-1,and the non-site calibration technology is being developed in the world.The landsat-8 OLI data with high calibration accuracy are cross-calibrated with the PMS multi-spectral data of high-resolution 8 meters,which verifies the application of domestic high-resolution multi-spectral remote sensing data in urban areas.The reliability of forest research provides a reference for the rapid development of high-resolution satellite radiometric calibration in China in the future.
