This is a space-time-cube visualization, an extension of a usual 2D map with time as the third dimension extending into the background. Like this, it is possible to understand temporal dynamics as a single glance.

Here, vegetation is visualized using a combination of different frequencies collected by the satellite. This results in a so-called spectral index on vegetation, ranging from 0 to 1. Dark green areas represent strong active vegetation while light green areas represent weak active vegetation.

Gray areas correspond to no collected data, usually because of clouds obstructing the satellite's view. The marked dot corresponds to the sensor tower location.
