effective education system can be realized with a personal 
computer. Through the experiences of using ENDIPS in training 
courses, the author have developed the interactive training 
system called ENDIPS-T (ENDIPS-Trainer) by revising ENDIPS. This 
paper describes about the ENDIPS-T. The system enables beginners 
to gradually learn the basic ideas of digital image processing 
focused on remote sensing. 
2. System Construction 
The hardware of ENDIPS-T consists of a 16bit personal computer, a 
key board, a color image display (640 pixel X 400 lines X 8 
colors) and two floppy disk drives(8 inches or 5 inches). Fig.l 
shows the hardware block diagram of ENDIPS-T. 
BASIC and Assembler language are used for software programming. 
In principle, the floppy in the first drive contains software and 
the floppy in the second drive contains data.

3. Data 
Typical remotely sensed data, such as Landsat MSS data, are 
usually used for training. One cannot deny the advantage of using 
real remotely sensed data for training from the very beginning. 
However, any real remotely sensed data has its particular place, 
time, sensor characteristics etc. In many cases, the beginners 
are apt to confuse the generality of basic ideas of digital image 
processing and the particularity of the remotely sensed data.
