:-\ Search in the Landsat Achieve of the Earth Explorer for the Landsat 8 scene from 13.12.2015 and download the scene as Level 1 product

:-\ Get familiar with loading raster data to R: Load a single raster band of the Landsat scene and plot it

:-\ Go to R and create a RasterStack of the listed channels 1-7.

:-\ Describe what information about the data you can get when you print the RasterStack

:-\ The scene is quite large. For further work on it, please crop it to the extent of Fogo using the crop function. Use the following corner coordinates for cropping: c(765000,795000,1638000,1667000)
