Abstract: The region of the Roof of the World is the highest region in the world, which covers the Qinghai-Tibet Plateau, the Hengduan Mountains, the Himalaya Mountains, the Hindu Kush, and the Pamir Plateau of nine countries, including China, Myanmar, Nepal, Bhutan, India, Pakistan, Afghanistan, Tajikistan, and Kyrgyzstan. We have produced eco-regional boundary data both in Google Earth .kmz and Arc/Info .shp formats, using scenarios of elevation more than 4000 m above sea level, land slopes more than 7 degrees, and integrated with the remote sensing images. Our boundary around the region is 22,089 km, with the total area of the region being 4,000,947 km2. Each of the 40 geographical parts of the boundary is identified and coded.

Key words: Roof of the World, Qinghai-Tibet Plateau, Hindu Kush Himalaya, eco-region, boundary data
