RESEARCH ON THE ACCURACY CONTROL OF DSM FOR A LOW LOUND AREA

Abstract

 Affected by global warming, it is estimated that the sea level is rising up to 59cm by the end of this century. For this reason, it is necessary to create especially the elevation date of lowlands along the sea. In this research, elevation data was created in accordance with two or more DSM creation methods. And, we examined the comparison method of DEM and DSM accuracy generated by each method and compared the accuracy of the DEM and DSM generated by GSI-10m, LP, ALOS/PRISIM, and ALOS/PALSAR.
