In this paper it is studied the development of Banat’s University of Agricultural Sciences and '’King Michael I of Romania '’ Veterinary Medicine between the years of 1987 – 2013 based on images taken from earth satellite. The analysis of this images are made using a program called ArcGIS. With the use of this program was obtained six normalized differences indexes and two combinations of spectral bands; in which it is possible to see how the area of USAMVB Campus had developed in 26 years. Satellite imagery consists of images of Earth or other planets collected by artificial satellites. Interpretation and analysis of satellite imagery is conducted using specialized remote sensing applications. Remote sensing refers to the use of aerial sensor technologies to detect and classify objects on Earth (both on the surface, and in the atmosphere and oceans) by means of propagated signals (e.g. electromagnetic radiation). Satellite imagery is also used in seismology and oceanography in deducing changes to land formation, water depth and sea bed, by color caused by earthquakes, volcanoes, and tsunamis. Because the total area of the land on Earth is so large and because resolution is relatively high, satellite databases are huge and image processing(creating useful images from the raw data) is time-consuming. Depending on the sensor used, weather conditions can affect image quality: for example, it is difficult to obtain images for areas of frequent cloud cover such as mountain-tops.
