The municipality of Dubai is the largest city of the Persian Gulf emirate of the same name, and has built a global reputation for large-scale developments and architectural works. Among the most visible of these developments—particularly from the perspective of astronauts on board the International Space Station—are three human-made archipelagos. The two Palm Islands (Palm Jumeirah and Palm Jebel Ali) appear as stylized palm trees when viewed from above. The World Islands evoke a rough map of the world from an air- or space-borne perspective. Palm Jumeirah and the World Islands are highlighted in this astronaut photograph.
