  The large scale map, an indispensable and important document is the basis for making compensation, support and resettlement plans when implementing land acquisition. The objective of this study was to use unmanned aerial vehicle (UAV) technology to create maps for ground clearance. The research conducted field survey using DJI Phantom 4 Pro UAV and 20MP CMOS digital camera synchronized with the aircraft. Images were collaged and edited by Agisoft metashape. From orthomosaic images, digitization/interpretation was performed directly on the image, the map edited by MicroStation, and Gcadas used to calculate the area. Research results have established a map of 1/500 scale, fully ensuring the quality and detail of land use classification and monitoring of assets on land for ground clearance work in the area research. Research shows that clearance map by unmanned aerial vehicles (UAV) was an effective technology in terms of products, time, cost and technology development trends.
