UAV LiDAR Systems for Mapping A Case Study of Khao Yai Area, Pak Chong, Nakhon Ratchasima

Abstract

The objective of this research is to study LiDAR mapping surveys installed on unmanned aerial vehicles (UAVs) and then use the results to create various topographic maps, both 2D and 3D, for use in designing construction cost estimates. The area studied checking accuracy of data obtained from LiDAR, the area studied is Khao Yai, Moo Si Subdistrict, Pak Chong District, Nakhon Ratchasima Province. The amount of study area is 3000 rai. Survey flight mapping with LiDAR using LiDAR brand Yellow Scan, Mapper model, installed on a DJI brand unmanned aerial vehicle (UAV), Matrice 300 RTK model, with the PILOT program. The work is divided into 2 parts: Part 1 is the operation of an unmanned aerial vehicle (UAV) equipped with LiDAR. It will fly automatically as designed and part 2 is the data processing and analysis part. Using the Yellow Scan Cloud Station program, the results of the study found that LiDAR mapping surveys installed on unmanned aerial vehicles (UAVs) can provide topographic information. with high resolution accuracy and can collect data quickly It uses much less workers than the original method, which data that have been pawned to check vertical accuracy with reference points on the ground at the same horizontal coordinate point to get an average difference of not more than 5 centimeters.
