Abstract
In order to achieve a sustainable society, it is important to grasp the Material Stock (MS) in use by society. Because of lack of statistical data, a new way to estimate MS is needed. In this paper, an estimation model that uses Nighttime-Light data and Synthetic Aperture Radar data is presented. This model was used to calculate the total building floor area in Aichi, Gifu, Mie, and Shizuoka Prefectures. It provides a division between urban and non-urban land use. The results show that in the case of urban land use, linear and non-linear modeling offer high estimation accuracy of ±10%. However, only linear modeling was accurate for non-urban land use. These accuracy levels are confident enough to be used for other regions or other countries in future research.
