Comparison of route survey profile information (longitudinal section) using different percentage UAV data slide-lap and end-lap / Mohamad Shahrir Aizat Saubi

This study investigates the achievable accuracy for route profile (longitudinal section) using UAV data captured at different percentages of side-lap and end-lap. Hence, objectives designed includes; i) to perform UAV data collection at different side lap and end lap (30%,60% and 70%,80%); ii) to ex...
