摘　　要：航天科技是国家综合国力和科技实力的重要体现,而卫星遥感则是航天科技转化为生产力最直接、最现实的途径之一。遥感数据获取与分发、数据处理与信息提取是卫星遥感应用的两个基本步骤。随着国家民用空间基础设施规划中的遥感卫星体系稳步推进,以及商业卫星遥感的蓬勃发展,我国的卫星遥感数据获取能力呈现质量齐升之势。但同时,作为卫星遥感应用的基础设施和关键工具,遥感图像处理系统平台逐渐成为制约自主卫星数据应用和空间信息业务发展的重要因素之一。本文围绕卫星遥感对地观测主题,从卫星遥感数据获取能力、卫星遥感数据处理系统平台两方面,对国内外现状进行综述,在此基础上分析了卫星遥感的发展趋势。Aerospace science and technology(S&T) is a direct indicator of comprehensive national power and S&T strength. Satellite remote sensing is one of the most immediate and realistic productivities transformed from aerospace S&T, which is composed of two broad procedures: remote sensing data acquisition and dissemination and data processing and information extraction. On the one hand, given the steady promotion of China′s Civil Space Infrastructure, the capacity for satellite image acquisition has been enhanced largely in terms of quality and quantity. On the other hand, an image processing platform is a considerable infrastructure for satellite remote sensing application. Platform development is increasingly becoming an important factor restricting the application of satellite remote sensing and the development of spatial information-related business. This paper reviews state-of-the-art status and analyzes the future trend of acquisition capacity and processing platform of satellite remote sensing image.In terms of data acquisition and dissemination, international open remote sensing satellites and sensors, such as Terro/Aqua-MODIS, Landsat, and Sentinel, have largely broadened and deepened applications of satellite remote sensing imagery. Data sharing policy and regularized senior image product enable the use of these commonweal data to analyze a long-term geographical phenomenon in a large region. Large commercial satellites, such as WorldView, Pleiades, and Radarsat, are operated by sizeable commercial remote sensing firms. The imagery obtained by big satellites helps promote the commercial value of satellite imagery in traditional industry applications, whereas small commercial satellite constellations, such as Flock, SkySat, and BlackSky, lower the barrier for more generalized and common applications. With the steady promotion of China’s Civil Space Infrastructure, China’s 27 civil remote sensing satellites in orbit can be broadly categorized into land, ocean, and atmosphere observation satellites.
