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.
