Maldives is a country of South Asia, situated in the Indian Ocean, south-southwest of India. It consists of approximately 1,190 coral islands grouped in a double chain of 26 atolls, spread over roughly 90,000 square kilometers, making this one of the most disparate countries in the world. Composed of live coral reefs and sand bars, the atolls are situated atop a submarine ridge 960 kilometers long that rises abruptly from the depths of the Indian Ocean and runs from north to south.

Only near the southern end of this natural coral barricade do two open passages permit safe ship navigation from one side of the Indian Ocean to the other through the territorial waters of Maldives. For administrative purposes the Maldives government organized these atolls into nineteen administrative divisions.[1] The largest island of Maldives is Gan, which belongs to Laamu Atoll or Hahdhummathi Maldives.[2] In Addu Atoll the westernmost islands are connected by roads over the reef and the total length of the road is 14 km.
