The buildings with metal structures return a strong signal to the sensor; therefore appearing bright white. Smooth surfaces which inlcudes alleys and the water in the lagoon, are black because they reflect a weaker signal.
Changes are visible in the image, for example,new objects appear bright green and objects that have disappeared appear in red. The progress of construction can therefore be monitored along with the movements of building materials and the appearance of new structures. The vegetation, which moves very slightly, is shown in a yellowish-green tone visible on the edges of the lagoon.
