“…During this stage, the following were performed: marking (materialization) on the field of some control points that would be used for the georeferencing of the obtained orthophotoplan; determining the coordinates of the points marked on the ground; flights were planned and carried out to obtain the photograms on the basis of which the orthophotoplans will be generated; having three areas/locations of interest, three photogrammetric flights were performed [40][41][42][43].…”

The use of scanning technologies and digital photogrammetry with the help of drones in the field of agritourism activities in Romania is a topic of novelty, because all the data necessary for the implementation or development of such research can be collected very quickly and with maximum efficiency. The classic methods are cumbersome and with a high consumption of inputs, and human and financial resources. The case study presents a practical method of applying this technology in the case of the agritourist farm REMMAR, from Vâlcea county, Romania, which wants to expand its agricultural production capacity with ecological products. Graphic support was obtained by scanning or digitizing existing maps in the physical/printed format and by acquiring data of interest in the digital format by photogrammetric methods and aerial field scanning of the studied area. The original elements of the topic are: how to obtain images by using photogrammetric methods; developing the methodology of the research and the actual development, from setting the basic objectives to obtaining and presenting the final results; elaboration of the methodology of the needs analysis and designing the specific data model; designing and the practical implementation of the geographic information system in terms of structure, methods, and means of software implementation. The successful implementation of the system was achieved only under the conditions of the existence of a data model specific to the field of action, and first realizing the conceptual foundation of the applicable data model, which would allow the registration, storage, extraction, processing, and effective analysis of the data of interest. From a theoretical and practical point of view, the research has a unique character in Romania, because it presents for the first time the development of a standard methodology for the design, expansion, and promotion of agritourism farms. The built geographic information system (GIS) is an effective tool for the management and control of the quality and efficiency of works specific to sustainable agricultural production.
