2022-06-09 A dataset of urban built-up area and SDG 11.3.1 indicators for the Beijing-Tianjin-Hebei region, China from 2000 to 2020 doi:10.11922/sciencedb.j00001.00277 en Based on time series of Landsat images, this study uses the Google Earth Engine cloud platform to extract built-up land in the Beijing-Tianjin-Hebei region, and integrates the results with GlobeLand30, GHS-Built, GAIA and GLC_FCS-2020 land cover products to derive the built-up land data set during the period 2000-2020 in the region. An overall accuracy higher than 90% was obtained. Based on this data set, the SDG 11.3.1 indicators-land consumption rate(LCR), population growth rate(PGR) and ratio of land consumption rate to population growth rate(LCRPGR) were calculated for each city.  Beijing-Tianjin-Hebei region; built-up area; land use efficiency; SDG11; Google Earth Engine SHU Lei ZHOU Meiling Linlin Lu CHEN Fang MA Yonghuan ZHANG Shuangcheng LIU Zhaohua PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset http://www.doi.org/10.11922/11-6035.noda.2021.0014.zh Science Data Bank
