## Tanakeke Island, Southwest Sulawesi, Indonesia

This circular island has a partly vegetated (light red) butterfly-shaped centre flanked by mangroves (dark red) and coral reefs. The colour of the coral reefs changes from bright white (exposed) to various shades of blue depending on water depth. On the main island of Sulawesi, beach ridges are clearly visible as parallel strips of red and greyish-green. It is a headland-bay coast with three rivers in the image, the middle one distinguished by abandoned meanders.
