This paper will focus on the administration or management of remote sensing data with the web based network communication. Though it is one of the important aspects to carry on esearch activities or encourage knowledge sharing, there is no adequate software to handle the remote sensing data in terms of cost and benefit. In this study, a free software package is developed for web based management system of remote sensing data from Terra ASTER and its performance is evaluated by comparing with the same type of existing systems. The advantage of our system is that it is designed to work under UNIX system in conjunction with the free software attached with that operating system. Another strength is the point that this system can be easily applied for other data source management such as Landsat and JERS-1 by modifying the corresponding module. An easy to use interface and processing system is expected to promote the use of ASTER data. The full package with UNIX compatible binary format is freely available via the FTP (ftp: //webmodis.iis.u-tokyo.ac.jp/ASTER/) .
