Construction of High Resolution Elevation Data from Paper Map for Numerical Model "RIAM-COMPACT"

We are developing the numerical model called the RIAM-COMPACT (Research Institute for Applied Mechanics, Kyushu University, Computational Prediction of Airflow over Complex Terrain). The object domain of this numerical model is from several m to several km, and can predict the airflow and the gas diffusion over complex terrain with high precision. First, we summarize elevation data that can be used with RIAM-COMPACT. Next, we concretely explain the construction of the high resolution elevation data from the paper map.
