It's a false-color image. The vegetation is in red, waterways and buildings are light green and blue.
One of the easier features to pick out of satellite images are airports, and the runways of the Tribhuvan International Airport are clearly visible near the centre of the valley.
This image demonstrates just a slice of Nepal’s varied terrain: from the mountains to the north to the plains in the south. We can see how water runs off of the mountains, forming large rivers that cut through the forested plain, with some areas of agriculture. The lower part of the image appears hazier than the mountainous areas because humidity is higher in the plains.
