资源简介：
This is a modified product of Geoscience Australia's Smoothed Digital Elevation Model (DEM-S) https://ecat.ga.gov.au/geonetwork/srv/eng/catalog.search#/metadata/72759.
The DEM-S layer has been modified by removing negative values by setting these values to zero. This layer has been snapped to a common extent to align with grids in the SVTM Modelling Grid Collection.
本数据集为澳大利亚地球科学局（Geoscience Australia）发布的平滑数字高程模型（Smoothed Digital Elevation Model, DEM-S）的衍生修改版本，原始数据来源链接为https://ecat.ga.gov.au/geonetwork/srv/eng/catalog.search#/metadata/72759。
该DEM-S图层已完成如下修改：将所有负值赋值为0以移除负值，并已对齐至统一空间范围，以匹配SVTM建模网格集合（SVTM Modelling Grid Collection）中的网格。
