The 3D modeling process consists of a three-dimensional representation of an object or a surface using certain specialized software. The 3D modeling was done by using a point cloud resulting from a drone flight. GIS applications enable the analysis of spatial locations by creating and layering information through maps or 3D scenes. In order to create a 3D model of the land, the ortophotomap resulting from a photogrammetric drone flight was used. The generation of the orthophotomap and the dense point cloud offers the possibility of making digital measurements, exporting and creating a database for making applications and drawing up interactive maps according to the user's wishes. The purpose of this work is to use the latest methods of obtaining photogrammetric data with the help of drones, but also to create interactive maps that allow studies and spatial analysis to be carried out. The case study was carried out on the campus of the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca using the photogrammetric method and GIS analysis. To obtain the orthophotomap and photogrammetric data, it was decided to fly with the DJI Phantom 4 RTK drone. The analysis of the orthophotomap of the campus and the dense point clouds allowed the graphical representation of the cartographic elements in the ArcGIS PRO application, respectively ArcGIS Online, offering the possibility of accessing them in real time, which represents an up-to-date process and to be considered for conducting studies and spatial analyses. The maps created, both in 2D and 3D format, as well as the WEB applications have the purpose of providing users with data regarding the shape, location, character and arrangement within the campus of the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca of the most important component buildings, taking into account their character.
