The use of Unmanned Aerial Vehicles (UAVs) for surveying is now widespread and operational for several applications – quarry monitoring, archeological site surveys, forest management and 3D modeling for buildings, for instance. UAV is increasingly usedby land surveyors especially for kinds of projects. It is still ambiguous whether UAV can be applicable for smaller sites and property division. Therefore, the objective of this project is to extract an orthophotomap, which can be used later by the land surveyor engineer in the field of cadaster, to vectorize correctly a topographic plan of the studied area. In order to achieve the correct result, the orthophotomap was created using a UAV, and more specific TRIMBLE UX5 HP. The flight schedule was prepared in the office with “Aerial imaging Desktop” software, and for the processing of the resulted photos was used “TBC - Trimble Business Center” software. Both of the softwares are provided by Trimble, the manufacturer of the UAV. The main problems associated with using a UAV are the level of precision and the visualization of the whole area. The results indicated that the precision is quite satisfactory with a maximum error of 5.33 cm for the rest of the model.
