In a developing country, it is important to estimate a impact of the construction of infrastructure to the environment. The shortage of the geographical data which is applicable to the environmental model is bottleneck of these process. In this report, using global mapping data which is distributed on every 1km mesh by Geographical Survey Institute of Japan, the applicability of these data to atmosphere, hydrology and soil erosion model was examined. In addition, integration of these models to improve the accuracy of model output was discussed.
