When a secular change of land covering is examined by using remote sensing data, a degree of solar radiation in the observation day and a difference in the growth conditions of the plant cause a trouble. In this paper, the method of getting rid of the influence that occurs by the difference in the weather condition is proposed, and a secular change of NVK (Normalized Vegetation Index) is examined. Furthermore, the new index NUI (Normalized Urban Index) to distinguish green covering and non-green covering without influences of solar radiation and the growth conditions of the plant is proposed. Secular changes in land covering of Kumamoto City is made clear by using NUI.
