遥感卫星原始数据格式分析及规范化研究

遥感卫星原始数据（RAW）格式不仅是遥感卫星地面系统运行和建设过程中的一个焦点问题，也是遥感数据用户十分关心的问题之一．目前，国内外对RAW数据格式的定义比较混乱，没有统一的行业标准，这种局面已严重影响到遥感卫星数据的高效使用及数据的长期存档，也严重制约了地面系统的进一步发展建设．本文通过分析国内外几种主流的遥感卫星RAW数据格式及特点，并结合中国遥感卫星地面站投入运行20年来的实践，提出了一种遥感卫星RAW格式方案，以期RAW数据格式早日规范化．

Remote Sensing Satellite RAW Data Format Analysis and Standardization Research

The remote sensing satellite RAW data format is not only one of the focus problems during the operation and development in the remote sensing satellite ground station,but Mso a problem the remote sensing users concern about.At present,the definition of RAW data format is in great confusion both at home and abroad,and no corresponding technical definition has been available so far.It has brought serious limitation to the usage of expensive satellite data and also brought difficulty on deciding how to save the data for long time storage,it has had great influence on the further development in the remote sensing satellite ground station.By analyzing the characteristics of some main existing remote sensing satellite RAW format combined with the operation experience over 20 years in China,a general RAW data format is proposed in this paper.RAW format has been adopted to our prototype system and well operated.Surely it is quite difficult to found a kind of RAW format standard with excellent compatibility and maneuverability.
