List of islands of Indonesia
The islands of Indonesia, also known as the Indonesian archipelago and formerly known as the Indian archipelago, may refer either to the islands comprising the nation-state of Indonesia or to the geographical groups which include its islands. According to the Indonesian Coordinating Ministry for Maritime Affairs, of 17,508 officially listed islands within the territory of the Republic of Indonesia, 16,056 island names have been verified by the United Nations Group of Experts on Geographical Names (UNGEGN) as of July 2017.
Transport in Indonesia
Indonesia has 21,579 km of navigable waterways (), of which about one half are on Kalimantan, and a quarter each on Sumatra and Papua. Waterways are highly needed because the rivers on these islands are not wide enough to hold medium-sized ships. In addition to this, roads and railways are not good options since Kalimantan and Papua are not like Java, which is a highly developed island. With the current length of waterways, Indonesia ranked seventh on the countries with longest waterways.
