Abstract: Remote sensing data characteristic of big data have been used for different kinds of applications, such as resource survey, environment monitoring, and natural disaster mitigation. However, the potential value of remote sensing data has not yet been fully developed. The building of remote sensing data engineering is conducive to intelligent analysis and information mining of remote sensing data, in which RTU (Ready To Use) production is a very important part. RTU products are ready for the follow-up application analysis, featuring radiation normalization, geometry standardization and global gridding. Based on satellite remote sensing data, this paper introduces the definition, production mix, the standard, geographic grid partition, etc. of RTU products for users’ reference. Through the CASEarth DataBank system (databank.casearth.cn), RTU products of multi-source satellite remote sensing data are open and shared.
