Open source solution to Geospatial Infrastructure for DEMETER observation data archives

In the area of Earth Observation, because Imaging Satellite Remote Sensing Data has been widely used in various fields, many studies have been carried out for its archive and "meta-data + file" approach, a de facto standard for imaging data's archive, has been widely adopted. However, Non-Imaging Satellite Remote Sensing Data, as scientific data, is mainly used in scientific research and has relatively narrow range of applications. The study of its archive method is lagging behind and a recognized archive mode has not yet been established now. As Non-Imaging Satellite Remote Sensing Data has characteristics of complex storage structure, high sampling frequency, large data volume and short repetition period, an proprietary efficient Non-Imaging Satellite Remote Sensing Data archive system is needed for its storing, retrieving, and data mining and analyzing. In this paper, characteristics of DEMETER observation data are analyzed at first, and then a management framework is presented for DEMETER observation data archive. At last, an open source based archiving system for the data is developed and conclusion is given for further research on China's earthquake electro-magnetic satellite data archive.
