Datasets description

 This dataset is derived from the latest released ASTER GDEM V3 tiled data. After preprocessing steps including gross error correction, null value filling, and removal of abnormal waterbody values, optimized 30m resolution DEM was generated through image mosaicking, projection transformation, and cropping.

Data source description

 The original DEM data originates from NASA's 2019 ASTER GDEM V3 dataset in GeoTIFF format, with WGS84/EGM96 as the vertical datum.

Data processing method

 The ASTER GDEM V3 tiled data was processed using ArcGIS batch processing tools for format conversion, mosaicking, and cropping to produce the 30m resolution DEM.

Data quality description

 The dataset features a spatial resolution of 1 arc-second (~30m), with invalid pixel values set to -9999, sea level data as 0, vertical accuracy of 20m, and horizontal accuracy of 30m.
