There are many government and commercial programs that acquire remotely sensed imagery from space platforms. Satellite imagery is collected for applications that include oceanography, watershed management, forestry, agriculture, urban planning and land use, mineral acquisition, and for other environmental and urban resource management needs. In this activity, you will download data from one of the most continuous space imaging programs in the world, the United States Landsat Program. Using Landsat 8 data, you will create image composites in natural color and false color.
