List of islands of Indonesia
The exact number of islands comprising Indonesia varies among definitions and sources. According to a geospatial survey conducted between 2007 and 2010 by Badan Koordinasi Survei dan Pemetaan Nasional (Bakorsurtanal), the National Coordinating Agency for Survey and Mapping, Indonesia has 13,466 islands. However, according to earlier survey in 2002 by National Institute of Aeronautics and Space (LAPAN), the Indonesian archipelago has 18,307 islands, and according to the CIA "World Factbook", there are 17,508 islands. The discrepancy of the numbers of Indonesian islands was because that the earlier surveys include "tidal islands"; sandy cays and rocky reefs that appear during low tide and are submerged during high tide. According to estimates made by the government of Indonesia 8,844 islands have been named, with 922 of those permanently inhabited.The following islands are listed by province:

Aviation in Indonesia
As of 2013, there are 673 airports in Indonesia, ranging from grand international airports to modest unpaved airstrips on remote islands or inland interior areas located throughout the archipelago. In November 2011, Indonesia had more than 230 conventional airports, most of them operated by Transportation Ministry technical operation units and state-owned PT Angkasa Pura I & II. Major airports are managed by Angkasa Pura; Angkasa Pura I operates 13 airports in Eastern Indonesia, while Angkasa Pura II operates 13 airports in Western Indonesia. After the 2000 aviation deregulation, Indonesian airports endured a surge of passengers, especially catalyzed by the advent of low-cost carriers. According to the Indonesian Transportation Ministry, 9 of the 13 airports managed by PT Angkasa Pura I have exceeded their passenger capacity.
