Processing: geometry simplified for display with a tolerance of 0.0002
degrees, islets under about 0.02 km² dropped and coordinates rounded to six
decimals. IDs 01-21 are assigned for this map; they are not official codes.

Istanbul has 39 districts. The map shows the twelve along the Bosphorus and
the Golden Horn: Sarıyer, Eyüpsultan, Kâğıthane, Şişli, Beşiktaş, Beyoğlu,
Fatih, Zeytinburnu and Bakırköy in Europe, and Beykoz, Üsküdar and Kadıköy in
Asia, plus Avcılar, Esenyurt, Küçükçekmece, Gaziosmanpaşa, Bayrampaşa,
Esenler, Güngören, Bağcılar and Bahçelievler, which join them to the west.
IDs 16 to 21 were added on 2026-09-23 from the same source. The boundaries follow the shoreline, so the Bosphorus and the Golden
Horn show as water. The map is for geographic learning, not navigation or
legal boundaries.

Sight coordinates were checked against OpenStreetMap features, with pins
representing locations rather than guaranteed entrances.
