For the researchers using satellite images, it is often very important to know the outline of satellite images or accompanying data with the images so that they can decide research targets, select images for their researches or confirm clouds conditions on the images. It is however very inconvenient and inefficient to check each of extraordinarily huge original satellite images preserved in CD-ROMs or magnetic tapes for the purposes. In fact, such high resolution as original ones is not necessary in those cases. Therefore, a catalogue database for satellite images with which one can easily obtain the information about the image outline, the accompanying date with the images and etc., has been strongly required. Recently, the WWW (World Wide Web) system on the Internet has been explosively expanding and accepted by the world-wide users because of the easiness on the multimedia handling, expandability, machine-independence and etc. Once a database is developed on the WWW, any WWW client can use the database without any additional software. Thus, the satellite image catalogue database on the WWW was developed. The database is based on the CGI concept of the WWW and the C and perl programming languages were used to develop the system software. The catalogue database has two functions. One is the catalogue image retrieval system and the other is the research history system with which one can leave and refer the research records on certain satellite images. The former service is given in both Japanese and English while the latter is only in Japanese at the moment. The portability to several UNIX systems is very high.
