The image is a map of a large body of water, possibly a lake or a river, with a red line running through it. The map is in Thai and appears to be a topographic representation of the area. The text on the map is written in both English and Thai, which translates to "Ao Yai Cape" in English. There is also a legend on the right side of the map that explains the different colors and symbols used in the map. The background of the image is dark, and the map itself is a light blue color.
