Abstract
Cadastral maps are an important part of cadastral documents, they are legal component of land administration in local authorities. Traditionally, a cadastral map is established by using land surveying methods which can provide high accuracy as required. In recent years, the UAV devices are developed and can provide an accurately tool for cadastral mapping on arable lands. This paper presents an evaluation of UAV application in cadastral mapping in comparison with traditional surveying for arable land. The results show that using UAV images in the mapping of agricultural land can achieve ground accuracy of 1,7 cm and height accuracy of 0,6 cm; In addition, when comparing the average accuracy of the 30 plot vertices and the mean lengths from 29 pairs of edges between the newly created map from the UAV image data and the map provided by the Department of Natural Resources and Environment of Phu Tho province, respectively is: 0,181 m and: 0,051 m.
