Abstract: This dataset, titled as elevation cluster dataset covering the eco-region of the Roof of the World (ROTWEVC for short), is 30-m raster data on land elevation classification in the eco-region of the Roof of the World. 17 classes of land elevation levels are identified from less than 500 meters above sea level to more than 8000 meters. The dataset is developed based on ASTER GDEM 2 and integrated partly with SRTM where the former data is not available. By statistics, the land located between 4500-5000 meters above sea level is 910,860 km2, which occupies 22.77% of the region; while the land above 4000 meters is 2,150,236 km2, 53.75% of the region is located in this high area. The area with elevation less than 4000 meters is mainly distributed around area of plateau, where is the transition zone from low altitude plain to high altitude plateau. 475 datasets with 1 × 1 degree latitude and longitude, the total volume of the data is 249 MB, compressed 194 MB.
