1. INTRODUCTION 
The importance of remote sensing for global environmental 
change monitoring is widely recognized. However, it is not 
easy for beginners to understand the sophisticated technology 
of remote sensing. In order to navigate beginners to learn 
how to use remote sensing technology for their own 
purposes, a software package Remote Sensing Navigator (RS 
Navi) was developed. 
2. OUTLINE OF RS NAVI 
The RS Navi is a kind of browsing software which allows 
users to find suitable information from the large amount of 
the contents recorded in the RS Navi CD-ROM. 
2.1 Contents 
The main contents of the RS Navi are as follows. 
• Application examples 
Various kinds of application examples are stored in the CD- 
ROM which includes land cover classification, forestry, 
agriculture, and sea surface temperature monitoring. 
Analysis procedure flow charts For particular application 
field, such as NDVI 
analysis or crop monitoring, the analysis procedure flowchart 
( see Fig. 2) is presented which guides beginners to nderstand 
how the practical data processing and analysis are performed 
in remote sensing. 
• Satellite data 
Several Landsat TM scenes of particular test sites are 
recorded in the CD-ROM for all seven bands. User can see 
each band image or color composite image of three bands, 
and enlarge a part of them with the display function of the 
RS Navi 
• Hyper text type dictionary 
In order for the users to understand the meaning of each 
technical words, such as MSS, BIL, MOS-1, cubic 
convolution etc., a remote sensing dictionary is stored in the 
CD-ROM. whenever user clicks the hi-lighted key words, 
the detailed explanation of the keywords will be displayed 
(See Fig. 3).
