  | [### DEM-H: Australian SRTM Hydrologically Enforced Digital Elevation Model ![](https://developers.google.com/earth-engine/datasets/images/AU/AU_GA_DEM_1SEC_v10_DEM-H_sample.png)](https://developers.google.com/earth-engine/datasets/catalog/AU_GA_DEM_1SEC_v10_DEM-H) |
  | The Hydrologically Enforced Digital Elevation Model (DEM-H) was derived from the SRTM data acquired by NASA in February 2000. The model has been hydrologically conditioned and drainage enforced. The DEM-H captures flow paths based on SRTM elevations and mapped stream lines, and supports delineation of ... |

  | The Smoothed Digital Elevation Model (DEM-S) was derived from the SRTM data acquired by NASA in February 2000. DEM-S represents ground surface topography (excluding vegetation features) and has been smoothed to reduce noise and improve the representation of surface shape. An adaptive process applied more ... |

  | [### Preview National Intertidal Digital Elevation Model 25m 1.0.0 ![](https://developers.google.com/earth-engine/datasets/images/ngis-cat/projects_ngis-cat_assets_DEA_NIDEM_sample.png)](https://developers.google.com/earth-engine/datasets/catalog/projects_ngis-cat_assets_DEA_NIDEM) |
  | The National Intertidal Digital Elevation Model (NIDEM; Bishop-Taylor et al. 2018, 2019) is a continental-scale elevation dataset for Australia's exposed intertidal zone. NIDEM provides the first three-dimensional representation of Australia's intertidal sandy beaches and shores, tidal flats and rocky shores and reefs at 25 m ... |
