资源一号02D卫星在轨测试自然资源典型应用

Natural Resources Typical Applications in On-orbit Test of ZY-1-02D Satellite

资源一号02D卫星搭载可见近红外相机和高光谱相机,是我国自主建造并成功运行的首颗民用高光谱业务卫星,可采集全色、8波段多光谱、166波段高光谱数据。在轨测试期间,自然资源领域根据相关行业标准和技术规范,结合载荷的数据特点与应用需求,开展了应用测试工作。文章基于在轨测试工作成果,对该卫星数据的应用能力与潜力进行了系统的评价。在轨测试应用表明:其丰富的光谱信息可对土地、地质矿产与环境、海洋等调查监测要素进行高精度解译,可在矿物识别、水质监测、土壤调查等方面进行定量反演;卫星数据满足自然资源调查、监测、监管和应急等相关业务,可为自然资源遥感调查监测提供高质量的数据保障。

ZY-1-02D satellite,equipped with visible near infrared camera(VNIC)and hyperspectral imager(AHSI),is the first civil hyperspectral operational satellite independently constructed and successfully operated by China,which can collect panchromatic,8-band multispectral and 166-band hyperspectral data.In its on-orbit test,the application test is carried out in the field of natural resources according to relevant industry standards and technical specifications,combined with the characteristics of payload data and application requirements.Based on the on-orbit testing results,the application capability and potential of the satellite data are systematically evaluated.The application evaluation during on-orbit test shows that the satellite data with abundant spectral information can be used in high-precision interpretation for survey and monitoring elements such as land,geology,mineral,environment and ocean,and is useful in quantitative inversion about mineral identification,water quality monitoring,soil survey and other aspects.The satellite data can meet the needs of natural resource investigation,monitoring,supervision,emergency response and other related services,which can provide high-quality data guarantee for remote sensing investigation and monitoring of natural resources.
