Landsat 7 is the Enhanced Thematic Mapper Plus (ETM+). ETM+ is a passive sensor that measures solar radiation that is either reflected or emitted.
LANDSAT is a series of satellites that photograph the Earth. The Landsat program is the longest running enterprise for acquisition of imagery of Earth from space. The first Landsat satellite was launched in 1972; the most recent, Landsat 7, was launched on April 15, 1999. The millions of images images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance, education and national security. Landsat 7 data has eight spectral bands with spatial resolutions ranging from 15 to 60 meters; the temporal resolution is 16 days.
Four main parts are 1. mapper 2. antenna 3. communications 4. data handling module functions: mapper- gathers detailed data about a strip of Earths surface. antenna- Landsat 5 then sends the data to a Landsat ground station solar panels- contains the mapper, antenna communication and data handling module
