The main image of the Irrawaddy (Ayeyarwady) River and some lakes in southernn Myanmar was created by applying the SAR-Sharpening technique.

This means that It is a composite image generated combining a high resolution Radar image with a medium resolution optical picture.

The two original images can be seen to the right, with the black and white ASAR radar image on one side and the colored MERIS one on the other.

The composite image is very sharp, with bright colors. The path of the river, the texture of the terrain and the outline of the lakes can all be seen perfectly.

However, in the separated images, the river is only clear by radar (this is in part caused by a difference in resolution: 30 meters for ASAR and 300 meters for MERIS).
