Accuracy assessment of LiDAR data using longitudinal profile of a road

الملخص EN

LiDAR data gives accurate elevation therefore ; we can obtain 3D modelling from LiDAR data which can be used for many applications such as civil engineering and surveying engineering, etc.

For accuracy assessment of LiDAR elevation data, a longitudinal profile are done from field survey using laser level instrument type (Leica Sprinter 100) of a road having about (350m) length, adjacent to the Building and Construction Engineering Department, which locates inside study area, then compares it with longitudinal profile, which drowns from LiDAR elevation data using (ArcGIS9.3) program.

According to the results analysis it can be stated that the elevations from the LiDAR data within accuracy of (3-10) cm can be obtained.
