Whole Earth centred on South America,showing also the continents of North America (at top) and Africa (at right). This image is a combination of hundreds of images acquired by NOAA weather satellites from orbits some 820 km above Earth. Each frame has a resolution of 1 kilometre. The mosaic of frames was then combined with a high-resolution digital elevation model. To emphasize relief features,the elevation model was stretched by a factor of two,and simulated solar illumination added | |
