# Reading in Sentinel-2 Images
Sentinel-2 is an observation mission developed by the European Space Agency to monitor the surface of the Earth [official website](http://www.esa.int/Our_Activities/Observing_the_Earth/Copernicus/Sentinel-2). Sets of images are taken of the surface where each image corresponds to a specific wavelength. These images can provide useful data for a wide variety of industries, however, the format they are stored can prove difficult to work with. This being, JPEG 2000 (file extension .jp2), an image compression format for JPEGs that allow for improved quality and compression ratio.
