The global 30 meter impervious surface data product contains the distribution information of impervious surface in the global land area. Compared with the existing similar products at home and abroad, it has a better extraction effect for some broken and small impervious surface objects. Data sources include USGS Landsat 8 surface reflectance data, ESA Sentinel-1 SAR data, NASA SRTM digital elevation data, NASA VIIRS night light data and GlobeLand30 land cover products of National Geographic Information Center.
