The Design and Implementation of the IDS Catalogue Data Archive System

摘要

Catalogue Data Archive System (CAS), as a background system, is the core part of the Internet Data Service system for Remote Sensing Data (IDS), which is a web portal published by CEODE and provides remote sensing data sharing and purchasing services. CAS integrates a series of updating methods and technologies, such as a suitable data transmittal mode, reflection, flexible configuration files and log information in order to make the system with several desirable characteristics, such as ease of maintenance, open and scalable, stability and minimal complexity. This paper describes the four major components of the CAS (Data Collector module, Metadata Convert module. Data Archive module and Data Inject module) and some of the unique features of the system, technical problems encountered and resolved.
