LiDAR Strip Adjustment With Polynomial Method
MetadataShow full item record
LiDAR Technology (Light Detection and Ranging), is a remote sensing technology which can measure the topographic height with the laser sensor that are contained on the aircraft. The point data in three dimension coordinate (x,y,z) are recorded in each strip as process in aerial photography. Calculation of height and error can be performed from the overlap area of each strip. The aim of this study is to adjust the vertical error which occurred in overlap area of LiDAR data. Distances between two strips in overlap area are determined for comparison. From the aerial photograph, the building features are used to control selection of points which are adjusted the vertical error with polynomial method. The result show that the building features in the aerial photograph which used as control points can reduce the vertical error and adjust the height values of LiDAR data along the recorded strips.
