Study the feasibility of airborne LiDAR on areal earth´s crust deformation surveying

Depicting people haven´t find out one efficacious method to rapidly survey the areal outburst geological disaster at present. Through analysing the characteristic and the status quo of the airborne LiDAR, the paper consider that airborne LiDAR can do it. In order to verify the feasibility of airborne LiDAR on areal earth´s crust deformation surveying. First, the paper analyse the error cause and shoud adopte quality control measures. Then, adopte net-RTK to survey many of points three dimensions coordinate in five different terrain regions (flat, river, town, hill, mountainous region). Second, Use DEM by airborne LiDAR points cloud on 3000 m altitude to interpolate vertical coordinate on same position. Third, compute the different value between datum and processing statistics and analysis to the different values. Last, The paper draw a conclusion that airborne LiDAR on 3000 m altitude can use areal earth´s crust deformation.
