Vegetation map of Qinghai Tibet Plateau in 1980s- A Big Earth Data Platform for Three Poles

Vegetation map of Qinghai Tibet Plateau in 1980s:

Region: Zhang Yili, etc. 2021 edition of Qinghai Tibet Plateau.

Data sources: Landsat 4-5 TM images from 1980 to 1988 (spatial resolution of about 30m), field survey data, 1:1 million vegetation map, Google Earth image, climate, terrain, landform, soil, land cover data, etc.

Mapping methods: (1) preliminary patch segmentation, using object-oriented method to preliminarily segment remote sensing images to form preliminary cartographic patches; (2) Visual interpretation: integrate the field survey data, 1:1 million vegetation map, Google Earth image, climate, terrain, landform, soil and land cover data to visually interpret and map the preliminary mapping patches; (3) Cross validation, using topographic map, 1:1 million vegetation map and land use map for logical verification; (4) The legend system adopts the classification standard, legend unit and system of vegetation map of the people's Republic of China (1:1, 000, 000), 2007, including vegetation type group and vegetation type 2 units. There are 11 vegetation type groups, 46 vegetation types and 10 non vegetation sections in the mapping area; (5) Vegetation map decoration adopts the method of combining map spots and numbers to represent different vegetation types and mapping units; (6) Based on the accuracy of the data used in the mapping, the maximum drawing scale of this drawing is 1:500000.

File naming and required software

The file is stored in ShapeFile format. The name of the vegetation map file of the Qinghai Tibet Plateau in the 1980s is "veg1980s shp”。 The contents of the document mainly include vegetation type vector data and attribute table fields, vegetation groups, vegetation type, vegetation type code. The vegetation classification unit is the same as that in the vegetation map of the people's Republic of China (1:1000). Data reading method: ShapeFile format files in the dataset can be opened by ArcGIS and other GIS software.
