ESTIMATION OF PARAPET HEIGHT USING LIDAR ORIGINAL DATA

Abstract

 We investigated a methodology to estimate the parapet height of the coastal structures by utilizing original data and ortho image acquired at the time of airborne LiDAR survey. By making comparison and examination of both terrestrial laser measurement data and airborne LiDAR surveyed data, the upper surface height of the parapet could be estimated precisely by our way and it was revealed that our methodology is highly effective for the confirmation of the change detection and the maintenance of the structures.
