Outline of Final Research Achievements |
In this study, the methodology to build a high precise digital elevation model (DEM) using simulation of flood diffusion inside city area was developed. The methodology was based on SfM (Structure from motion). Three dimensional model derived from SfM does not have location information. Therefore, some ground control points (GCP) should be utilized. The relationship of number and distribution of GCP and accuracy of DEM was to clarify. Additionally, the height of UAV, a kinds of camera has revealed the impact on accuracy. Finally, the DEM built by our developed method ware confirmed that available for the simulation of flood diffusion inside city area.
