The authors intend to develop the environmental education through satellite images, especially in using by LANDSAT images, as one of the best ways for visualized educational means. In recent years, many kinds of remote sensing systems are improved remarkably and are indispensable for understanding physical system of the earth. Especially, the LANDSAT images prepare the information for large area simultaneously and repeatedly.<br>The understanding of physical system means the understanding of earth's radiative equilibrium because solar energy is the only one energy that the earth receives within the solar systems, the earth-atmosphere system, or solar-earth system as more global physical system. The information obtained from images by TM (Thematic Mapper), on-board LANDSAT 4 and 5, are very valuable for understanding the system because each band of the TM are reflected solar energy (Bands 1 through 5 and 7) and long wave radiation (Band 6) from the earth-atmosphere system.<br>The purpose of the environmental education is to bring up environmental ethics according to the understanding of physical system. For this purpose, learning the urban heat island phenomena, the most serious problem for the disruption of the physical system as thermal pollution, is the one of the best ways to experience the disruption of the system. Therefore, to recognize the urban heat island phenomena visually, from the LANDSAT images is the very excellent way for understanding the thermal pollution of the system from personal experiences.
