Remote sensing is the technical field that deals with the detection, measurement, recording and visualization in the form of images, of electromagnetic radiation, emitted by objects and phenomena on Earth or in the Universe, from a distance, without having direct contact with them. The present research had as main objective the study of agricultural land based on the spectral information obtained from satellite images, the study area being within the Experimental Didactic Station of the BUASMV Timisoara. The purpose of this paper is to highlight the efficiency of remote sensing, satellite technologies, regarding the acquisition of data from the Earth`s surface and their interpretation, so that the obtained results serve as many fields of activity as possible. In order to reach the research objectives, the Sentinel 2 remote sensing system was used, the images being downloaded from the portal www.planet.com. The Sentinel-2 mission has the following capabilities: Multi-spectral data with 13 bands in the visible part, near the infrared and the one with the infrared short wave of the spectrum; Systematic global coverage of land areas from 56 ° S to 84 ° N, coastal waters and the entire Mediterranean Sea; Review every 5 days from the same viewing angles. At high latitudes, Sentinel-2 overlaps, and some regions will be observed twice or more every 5 days, but with different viewing angles; 10 m, 20 m and 60 m spatial resolution; 290 km field of view; Free and open data policy. The use of vegetation indices in the field of precision agriculture represents a new and of great interest for an adequate management of agricultural crops. In recent years, various studies have aimed at correlating vegetation, soil or water indices, calculated from remote sensing images, from drones or from the camera with data collected from the ground in order to increase agricultural productivity.
