PRECISION OF DEM AND ITS INFLUENCE ON A RESULT OF A SEISMIC STABILITY ANALYSIS OF SLOPE
In this study, the precision verification was performed about DEM (Digital Elevation Model) with the 10m grid spacing, and examined about the influence on a result of a seismic stability analysis of slope which is based on the features analysis of the micro-topography. As the results, it founds that the safety factors by the seismic stability analysis of slopes with DEM are very different from the safety factors which were calculated with the use of field surveying terrain information, because it became an average on the elevation values and became a smooth slope in case of using the DEM with 10m grid spacing.
