This false-colour image shows agricultural structures near Hail, Saudi Arabia. The circular features are created by centre-pivot irrigation systems, where a long water pipe rotates around a well at the centre. The shades of red indicate how sensitive is the Deimos-1’s multispectral instrument to differences in chlorophyll content and vegetation cover, providing key information on vegetation health. In this image, the brighter reds indicate more photosynthetically active vegetation. Due to the scarcity of surface water in the Arabian península, the wáter used for agricultural activities is drained from fossil reservoirs at around 1 km depth.
