In a previous article titled "「GIS Data」Chinese Geographic Region Partition Vector Data", we shared vector data on geographic region partitions. Recently, some users in our group requested geomorphological data. After searching, we actually found a 1:1,000,000 geomorphological type spatial distribution dataset from the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences (CAS), and are sharing it with everyone.

Data Information

The China 1:1,000,000 Geomorphological Type Spatial Distribution Data originates from the "Geomorphological Atlas of the People's Republic of China (1:1,000,000)". This atlas comprehensively reflects the macro patterns of China's geomorphology and reveals the spatial differentiation of regional landforms. It is a national fundamental scale atlas within the million-scale thematic map series already published in China, and it is the first integrated land-sea fundamental scale atlas in this series. It is also the first internationally completed four-fold quarto international sheet division one-millionth geomorphological atlas globally, filling a gap in this field both domestically and internationally. It has promoted the progress of geomorphological research, and the research成果 (results) have been widely applied in national land surveys, regional planning, environmental protection, and disaster monitoring across China.

The atlas was compiled by the Institute of Geographic Sciences and Natural Resources Research, CAS, in collaboration with relevant national research institutes, universities, and mapping units, and was published by Science Press in 2009.

Main Geomorphological Types Included

The China 1:1,000,000 Geomorphological Type Spatial Distribution Data includes the following geomorphological types:

11 Low Altitude Plain 12 Medium Altitude Plain 13 High Altitude Plain 14 Extremely High Altitude Plain 21 Low Altitude Platform 22 Medium Altitude Platform 23 High Altitude Platform 24 Extremely High Altitude Platform 31 Low Altitude Hills 32 Medium Altitude Hills 33 High Altitude Hills 34 Extremely High Altitude Hills 41 Low Mountains with Small Relief 42 Medium Mountains with Small Relief 43 High Mountains with Small Relief 44 Extremely High Mountains with Small Relief 51 Low Mountains with Medium Relief 52 Medium Mountains with Medium Relief 53 High Mountains with Medium Relief 54 Extremely High Mountains with Medium Relief 62 Medium Mountains with Large Relief 63 High Mountains with Large Relief 64 Extremely High Mountains with Large Relief 72 Medium Mountains with Extremely Large Relief 73 High Mountains with Extremely Large Relief 74 Extremely High Mountains with Extremely Large Relief

Specific types can be viewed using the identify tool in GIS software. Taking QGIS as an example, after opening the data, use the identify tool to click on the map and view the geomorphological type at that location.
