Earth observation and space analysis of land areas, oceanic and atmospheric phenomena is a necessity nowadays.
European Space Agency (ESA) is developing a new family of satellites, called Sentinel, in order to perform the operational needs of the environmental monitoring program, Copernicus. Since 2014 until now ESA have successfully launched four satellites, which have a proven track record.
This paper contains information about Sentinel constellation, features of the satellite images and also the applications of Sentinel satellite images. This paper also describes how to purchase satellite data and the software that can be used to view and analysis data are named.
The aim of this paper is to analyze the changes of land cover and land use of study area, in two different periods, based on Sentinel satellite images.
