The system uses the idea of project management to manage the vast amounts of earth science data and map files. In displaying map files, the system connects with Access database and uses Notepad to show its metadata at the same time. The system uses catalogs and file tree management achieves to integrate, manage and display map files, and through Access database stores metadata and manages catalog tree location.
