| 摘 要： | 我国现有的风云系列卫星、资源卫星及海洋卫星都可实现多种性能的对地观测,在灾害与环境监测方面发挥了很好的作用。然而,面对复杂多样的自然灾害及环境问题,这些卫星却都难以完全满足灾害和环境监测与预报所需的空间分辨率、时间分辨率和光谱分辨率以及全天候的要求。主要对环境与灾害监测预报小卫星A、B(HJ-1A/B)星多光谱遥感数据进行了质量评价,提取数据特征,以便为该数据的推广应用提供参考。

| Abstract: | China’s current series of satellites,such as FY satellites,resources satellites and oceanographic satellites can all achieve a variety of earth observation performance; they had played a very important role in disaster and environmental monitoring.However,in the face of complex and diverse natural disasters and environmental issues,these satellites are difficult to fully meet the requirements of the spatial resolution,temporal resolution and spectral resolution in the disaster and environmental monitoring and prediction,so does the all\|weather requirement.For the small satellites A,B (HJ-1A/B),which work on environment and disaster monitoring and forecasting,the paper makes assessment on data quality of the multi-spectral remote sensing data,then extracts the data features,and is aimed to provide a reference on its use and extension. |
