Types of surface vegetation within 500m of China Pakistan Economic Corridor and Tianshan Mountains (2020)-National Tibetan Plateau Data Center

This data set collates and collects the surface vegetation type data with 500m spatial resolution in the Qinghai Tibet Plateau and its surrounding areas. The data source is from the official website of the United States Geological Survey (USGS)（ https://lpdaac.usgs.gov/products/mod12q1v006/ ）This data is the land use and cover product of MODIS level III data, with a spatial resolution of 500m. By using supervised classification of Terra and aqua reflectance data. By applying smoothing splines to the bottom bidirectional reflectance distribution function (BRDF) - adjusted reflectance (nbar) time series, the 6th mcd1201 product developed a new notch filling spectral time feature. In addition, the 6th edition also uses hidden Markov model (HMM) to reduce false changes in category labels. The data set contains 17 major land cover types, including 11 natural vegetation types, 3 land types for land development and mosaic and 3 non vegetation land type definition types according to the international geosphere biosphere program (IGBP). They are: 1-evergreen coniferous forest; 2-evergreen broad-leaved forest; 3-deciduous coniferous forest; 4-deciduous broad-leaved forest; 5-mixed forest; 6-dense shrub; 7- sparse shrub; 8- woody savanna; 9- savanna; 10- grassland; 11- permanent wetlands; 12- agricultural land; 13- cities and construction areas; 14- agricultural land / natural vegetation splicing; 15- snow and ice; 16- bare ground; 17- water.

File naming and required software

"File naming: vegetation type data is stored in grid form (TIF), and the file name is" xxxx.tif ", where XXXX represents the data range.
Data reading method: the data is saved in TIF format, which can be opened by any software that can open TIF files. It is recommended to use ArcGIS, QGIS and other geographic information software. "
