The Amur River Basin, also known as the Amur River Basin, is composed of a series of low to medium mountains and plains, with the highest point being Mount Kent at an altitude of 2473 meters and the estuary at 0 meters. On the basis of ASTER-DEM data, after data denoising and reconstruction, it is divided into 8 levels according to changes in altitude, namely: Level 1 (<50 meters), Level 2 (50-100 meters), Level 3 (100-200 meters), Level 4 (200-500 meters), Level 5 (500-1000 meters), Level 6 (1000-1500 meters), Level 7 (1500-2000 meters), and Level 8 (>2000 meters). Statistics show that the geographical distribution area of the Heilongjiang River Basin with an altitude between 500 and 1000 meters is the largest, reaching 803402.10 square kilometers, accounting for 38.58% of the total basin area; Next is the area between 200 and 500 meters, with an area of 605881.74 square kilometers, accounting for 29.10% of the total basin area. The area with the smallest area is over 2000 meters, covering 939.81 square kilometers, accounting for 0.05% of the total basin area. The altitude dataset of the Heilongjiang River Basin is stored as raster data in. tif format, with a compressed data size of 64.8MB.
