Urban land use change data in Central Asia (1985-2018)

This dataset includes year-on-year data on urban construction land changes in five countries in Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan) from 1985 to 2018. The data has a spatial resolution of 30m and a temporal resolution of one year. It is derived from the Global Artificial Impervious Area (GAIA) change data extracted from Landsat images from 1985 to 2018 (Gong Peng et al.). The researchers evaluated 7 sets of data every 5 years from 1985 to 2015. The average overall accuracy is over 90%, and it is the only urban construction land dataset spanning 30 years.

Data file naming and use method

The data is saved in the "centralAsia_GAIA.tif" file. The pixel values 1-34 corresponds to the years of 2018-1985. A pixel value of 0 means that it is not urban land until 2018.
GeoTIFF files can be read and opened with ArcGIS software and GDAL.
