Development of the providing and management system for the evaluated-information on the satellite-data characteristics

Abstract

Due to the advancement and diversification of the earth-observation satellite, this paper points out the necessities of providing and managing the Evaluated Information (termed EI) on the characteristics of the satellite data newly observed. As occasion demands from the end-users, those evaluated-information are continuously produced according to the following points of view: 1) pre-image processing, 2) image analysis, and 3) post-image processing. Furthermore, we have been tackled to construct the Internet based-supporting system for providing the EI, and to investigate the practical use of those through the network. The structures of the data sets on the EI are divided into two sites as the “Web site” and the “Data Base (DB) site”, respectively. A huge amount of information resource in the Web site is managed by the “DSMS (Data Set Management Systems)”. Without being disturbed in the management for the data sets, the users can only attend to retrieve the stored data sets through environment. Based on the unitary management of the data sets according to the kinds of satellites, the improvement of the work efficiency as well as the continuity in collecting, storing and managing the data sets on the EI could be achieved. Such a systematized approach might be essential to promote the future progressive satellite data.
