XML기반의 그리드데이터 메타데이터 교환체계 구축 방안 제시

Proposing XML based Integrated Griddata Metadata Accessing Method

Nowadays, the demand of the output analyzed from the gridded data has been sharply increased as the remote sensing technologies and GIS related industry have been developed. Therefore, a metadata access system which fits the requirements of the users should be developed for better managing and utilizing gridded data. In this background, this study defined a common application schema through the analysis of the metadata built by numerous institutes based on the draft metadata standards proposed from the study which maily concentrated on establishing the standards of distributing metadata for the gridded data supported by ETRI at 2003. Also, XML based integrated system was developed to access metadata maintained by SaTReC as well as SIMC to facilitate more convenient data access for the grid data users. The results of the pilot system developed from this study can be expected to contribute to build an more efficient and enlarged integrated access system of the metadata for the gridded data.
