In organizations like ‘The organization Registration of Documents and Estate’ that users need update and precise Information of varieties of land properties, traditional surveying cannot meet the today’s needs. This research with the aim of assessing and comparing land surveying method by using of UAV photogrammetry has done. For this purpose, imaging by UAV Phantom4 pro V2 from residential context in the height of 80 meter, with the length and width of 80% designed and then coordinates’ determination of land surveying control points including 12 points (6 control points and 6 check points) by the GNSS/RTK rover, which has done with the help of Shamim Network. Triangulation and photogrammetry computation in Agisoft (photoScan) environment and transformation operation and coordinates’ determination of properties vertex (map preparation) is done. Length of the property sides achieved by UAV photogrammetry method along with deeds lengths are extracted from Comprehensive Cadastral Database and compared in terms of precision, time and cost and the results show that the use of UAV photogrammetry method not only has a good precision and low amount of error for control points (RMSE: X=3.51,Y=4.94, Z=0.60cm) and check points (RMSE: X=3.87 ,Y=5.75 Z=2.38cm) but also are suitable for preparation of 1:500 map. Additionally, according to the achieved results the cost of UAV photogrammetry is 25% of land determination coordinates and the time devoted to UAV photogrammetry is 31% of the time of land determination coordinates. Therefore, UAV photogrammetry method in terms of cost and time is also cost effective.
