Gaofen-3 is a Chinese remote sensing satellite with multiple working modes. among which the scanning synthetic aperture radar (ScanSAR) mode is used for wide-swath imaging. synthetic aperture radar (SAR) interferometry in the ScanSAR mode provides the most rapid way to obtain a global digital elevation model (DEM). which can also be realized by Gaofen-3. https://jalyttlers.shop/product-category/coffee-tables/
