Our research purpose here is to analyze the influence of the change of land covering in the sutra age to the earth albedo as well as other earth surface information using the LANDSAT-TM data. A high resolution satellite data were analyzed to get the detail albedo in the city. NVI, surface temperature and the albedo showed that a correlation-like change was being done due to the change in land covering in the sutra age. Although the albedo of the artificial covering is supposed to take a high value, a low value of the albedo is shown by the present research in the city area. Therefore, an albedo by IKONOS was calculated. The technique to make the shadow figure of the detai city from the artificial satellite was shown newly. It was very clear that a shadow influenced the decline of the albedo in both comparisons.
