Abstract
If we could have access to an optical disk as we have access to a floppy disk or a hard disk, large scale multispectral data analysis will be done on a personal computer system. The authors have studied and developed a personal computer system with optical disk drive system as the external memory which enables us to analyze such huge data, which could be only analyzed by a large computer or special data analysis system so far. Using this system, Landsat TM data for one scene about 300 Moytes can be written upon a side of a five quater inch optical disk. The written data are read out with random access from the optical disk and processed by a personal computer. This point is the most remarkable in this newly developed system.
Further, to serve the system to general MSS data analysis, we connect the software with the formerly developed Remote-10 by which we can perform the multi-spectral data categorization very fast. The design concept of the system involves large scale data handling, fast processing, and full color graphics presentation utilizing easily a personal computer. This system may give a suggestion to the future data delivery system of Landsat, Spot, Noaa satellite data, and also to the future data analysis system also. This system may become popular for an educational use at a laboratory level, because of the easy data handling, the easy data accessibility, and the reasonable system cost.
