Example of an imagette from ERS-2

Example of an imagette from ERS-2. Imagettes are 10 by 5 km samples of the sea surface acquired by the satellite's SAR instrument as it works in Wave Mode every 200 km. Normally they are then converted into ocean-wave spectra, but raw imagettes are useful in themselves, and have been used to carry out a global census of so-called rogue waves.
