The topographic survey (detailed topographic survey) presents the real situation on the ground, measured in national coordinates, in the case of Romania in the Stereographic 1970 system. Practically speaking, we are talking about measurements or a set of works necessary to document the real situation on the ground. Or, even more concisely, the determination of level elevations relative to the level of the Black Sea. Plotting represents the topographical operation through which certain points in a project are materialized in the field by staking out. The purpose of this paper is to present the workflow for the mapping by modern methods of experimental fields with fodder plants included in field combinations. The tracing was performed with GNSS technology, the marking accuracy being ± 2.3 cm. In the case study presented below, a current orthophoto plan of the studied area was made using the eBee AG drone, after which a topographic survey was made using the South Galaxy S7 GNSS equipment. On the basis of the orthophoto plane and the data obtained from the topographic survey, the plan was drawn up for the plotting of the experimental fields, which was carried out with the help of the Leica Viva GS07 GNSS equipment. In this way, precise and reproducible results can be obtained in agricultural experiments, being a more expeditious method than the classical method.
