The scientific and technological progress recorded in the last years in the field of geodesy, cartography and land surveying allows the use of some modern techniques and methods towards realizing some complex objectives. This evolution of techniques allows for high level accuracy data to be obtained in short period of time, on large surfaces. U.A.V. photogrammetry serves a wide variety of domains. The present study follows an interdisciplinary research, and modern concepts from land improvement field are approached. For the photogrammetric flight a DJI Phantom 4 Pro drone was used. The photos were taken after a manual flight conducted with the DJI GO application. The generated dense point cloud consists of 82191720 points, having both spatial coordinates and an RGB code. The resulting orthophoto map has a ground resolution of 1.37 cm/pixel. Also, within the project, the Digital Elevation Model (DEM) was obtained which has a resolution of 2.74 cm/pixel, the point density being 1335.85 points/m2. The obtained products can be exported, thus allowing them to be integrated into specialized software for further analysis.
