The purpose of this study is to build an environmental information database system for education through the use of remote sensing image data and geographical information. Satellite remote sensing data are useful for environmental education. The data include atmospheric scattering effects, which must be removed before the data are used in educational materials.This study's conclusions can be summarized as follows :1) We adopted NOAA/AVHRR data as the educational resources and analyzed AVHRR reflectance data in the visible wavelength channel. In this study, the atmospheric correction scheme for AVHRR data over land was carried out using the correlation between the visible reflectance and middle infrared reflectance.2) We estimated the aerosol optical thickness using AVHRR data. We assumed an atmospheric-ground surface model for the atmospheric correction. The aerosol optical thickness is the most important parameter in that model. In this study, we retrieved the aerosol optical thickness over land surfaces using AVHRR surface reflectance data. We found that variations in the surface reflectance affect the sensitive estimation of the aerosol optical thickness.3) We developed a satellite image reference system for students to use in their outdoor activities. This system uses a blinking cursor to display positional information from the GPS. Students can identify their own position on the geometrical corrected image by consulting the GPS.

本研究的目的是利用遥感影像数据和地理信息建立教育环境信息数据库系统。卫星遥感数据对环境教育是有用的。本研究的主要结论如下：1)以NOAA/AVHRR数据为教育资源，对可见光波段的AVHRR反射率数据进行了分析。本研究利用可见光反射率与中红外反射率之间的相关性，对陆地上的AVHRR数据进行了大气校正。我们采用大气-地面模式进行大气校正。气溶胶光学厚度是该模式中最重要的参数。在这项研究中，我们利用AVHRR地表反射率数据反演了陆地表面的气溶胶光学厚度。我们发现，地表反射率的变化会影响气溶胶光学厚度的灵敏估计。3)我们开发了一个卫星图像参考系统，供学生在户外活动中使用。该系统使用闪烁的光标来显示来自GPS的位置信息。学生可以通过参考GPS来识别自己在几何校正图像上的位置。
