Abstract:
This research offers a comparative examination of the conventional and unmanned aerial vehicle (UAV) methodologies for land surveying. The objective of our study is to evaluate the precision, efficiency, economic viability, transparency, workforce demands, and other pertinent considerations linked to the utilization of these two survey techniques. Our study employed a research methodology that entailed carrying out land surveys in diverse locations using both conventional and unmanned aerial vehicle (UAV) techniques. The data was obtained from Sector A2 of DHA Quetta via conventional ground-based measurements and aerial imagery acquired by unmanned aerial vehicles (UAVs) that were equipped with photogrammetric capabilities. After data collection, suitable software tools such as AgiSoft were employed to process and analyses the data, resulting in precise measurements and volumetric computations. Several significant discoveries surfaced from the examination of the research data. The results indicates that utilization of unmanned aerial vehicles (UAVs), specifically photogrammetry, presents notable benefits compared to the conventional approach in various aspects such as precision, efficiency, affordability, transparency, workforce productivity, and feasibility in difficult topographies. The findings of this investigation augment the existing corpus of knowledge pertaining to surveying methodologies and have the potential to inform the decision-making procedures of practitioners operating within this domain.
