How to read this map
Countries with a coast on the Bosporus Strait: Turkey.
The blue outline marks the Bosporus Strait as mapped by Natural Earth. Towns and cities on the map include Istanbul, Bursa, İzmit, Adapazarı, Adapazarı and Tekirdağ.
Greens show lower elevations; tan and brown show higher land, with pale tones toward the highest terrain. Shadows emphasize the slopes, and vertical relief is exaggerated so landforms are easier to read. Dashed lines show country borders.
The relief uses Terrain Tiles (SRTM, GMTED2010 and ETOPO1 elevation data). Rivers, lakes, borders and the outline of the Bosporus Strait come from Natural Earth, and the figures on this page from Wikidata. Natural Earth draws features at a small scale, so the outline is a guide to where the Bosporus Strait is, not a surveyed boundary.
