ABSTRACT: 
Since 1992, the National Space Development Agency of Japan(NASDA) and the Economic and Social Commission for 
Asia and the Pacific(ESCAP) have been co-organizing the Regional Remote Sensing Seminar on Tropical Ecosystem 
Management every year in some country in Asia. In this seminar, the authors have been performing a three days PC 
based hands-on-training on remote sensing and GIS for beginners. This paper describes about the outline of the training 
and discusses about the optimization of PC based training for remote sensing and GIS. 
The main objective of the training was to transfer not only knowledge but also technology of remote sensing and GIS to 
the beginners. Several software as well as data sets were prepared for the training and provided to the trainees on free of 
charge. The software were designed not only for training but also for practical data analysis. A large amount of data were 
stored in CD-ROMs for easy handling with PCs. All these situations allow trainees to smoothly step up from training to 
real analysis at their offices with their PCs after the training. For optimizing this kind of training, the training period, 
number of instructors, and number of PCs should be considered carefully.
