Abstract 
An interactive training system using a personal computer has been 
developed. This system allows beginners to understand the basic 
ideas and methods of remote sensing technology focused on digital 
image processing. 
Through the interactive operation of the system, like computer 
games, the beginners can learn basic ideas of remotely sensed 
data processing and improve their technique. The menu includes 
level slicing, multi-band color composite, classification and 
geometric correction. 
1. Introduction 
According to the progress of computer technology, these days, 
digital image processing can easily be performed by using 
personal computers. In RESTEC, we have developed personal 
computer image processing system called ENDIPS(End-users Image 
Processing System) in 1984. ENDIPS has been used for training 
courses in RESTEC for several years and has been welcomed by the 
trainees. The software of ENDIPS has been modified and released 
by NEC Aerospace Systems, Ltd. in the name of LODIA (Low-cost 
Digital Image Analyzer). 
Nowadays this kind of system has become so popular in the remote 
sensing community that it is almost difficult to find people who 
are not using personal computers for remote sensing. However, 
this does not mean that digital image processing itself has 
become easy. In general, image processing algorithms used in the 
personal computer systems are almost same as those of 
conventional computer systems. Even though each beginner has 
become able to use a personal computer for his training, the 
effort he has to make for learning has not changed so much from 
which of conventional computer systems. 
However, if ihe graphic functions and interactivity. in. which 
personal computers have priority to conventional computers are 
effectively used in the training and learning process, a very
