Remote Sensing (RS) enables land cover investigation and earth surface environmental investigation from the global scale to several kilometer regional scale by multispectrum analysis of physical information on the basis of observation performance such as wavelengths and spatial resolution of observation. On the other hand, it is possible to graphically and statistically analyze using Geographical Information Systems (GIS) about the information that cannot be extracted from remote sensing, or the information of conventional socio-statistics. In addition, Computer Aided Design (CAD) for structure design enables automatic design processing. This study attempted construction of land resource database by means of integration of the above three systems that have different characteristics. The database provides a foundation for studying global light distribution, assessing land cover change resulting from human activities and planning infrastructure construction.
