TY - Data T1 - Arab 30m resolution digital elevation model (DEM) data A1 - Han liqin DO - 10.12072/ncdc.NIEER.db0101.2020 PY - 2020 DA - 2020-11-04 PB - National Cryosphere Desert Data Center AB - Based on the domestic and foreign stereo imaging satellite data, the data set is optimized, partially corrected and corrected. The gross error correction, null value filling and water area numerical anomaly elimination are adopted to generate the optimized 30m resolution digital elevation model (DEM) through image mosaic, projection transformation and clipping.
