| PKU Urbanscape Essential Dataset (PKU-USED)【Request】 |
The urban functional-zone is a space carrier for urban residents to engage in various socio-economic activities, such as commercial, residential, industrial and shantytowns, and is formed by a combination of natural, social, economic, and historical factors. The rational layout of urban functional-zones is of great significance to promote production, facilitate residents' lives, improve the ecological environment, and efficiently use land resources.
PKU-USED was extracted using the functional-zones mapping tools we developed based on the ZY-3, GF-6, Google Earth imagery and ArcGIS images. It contains 81 major cities in China. According to the "Code for classification of urban and rural land use and planning standards of development land" (GB50137), urban functional-zones are divided into 12 categories.
