UAVs (Unmanned Aerial Vehicles) are commonly used in photogrammetric observations in research fields like agriculture, archaeology, industry and construction of base maps. They present several advantages like low-cost platforms, rapid results, highpositioning accuracy and less labor effort in the field.In this study, we evaluate the positioning accuracy of UAV based photogrammetrywith conventional observation techniques in a sample area. Our main motivation is toexamine if the final model of a low altitude UAV can reach the positioning accuracy ofconventional observation techniques, especially in residential regions. For this purpose, weevaluate the results of 3 separate photogrammetric flights in a pre-observed field. Resultsindicate that low-altitude UAV flights can provide high accuracy both in 2D and 3D positioning in residential and densely constructed areas.
