Spatial distribution data of urban land use in Pan-Third Pole region (1992-2015)

1) Data content: Vector data of urban built-up areas in 65 countries of the pan-third pole region from 1992 to 2015.
2) Data source and processing method: Based on the global land cover data of the 300-meter resolution of the ESA JCR from 1992 to 2015, we integrated the global urban land use data of Gong Peng, Liu Xiaoping and Chen Jun to obtained a correction data set.
3) Data quality description: The accuracy of data in 65 countries is about 75%, and there may be differences in data accuracy in different regions.
4) Data application results and prospects: It can be used for urbanization related research in 65 countries in the Pan-Third region, such as urban land expansion analysis and future scenario simulation.
