description: |
  Height of the land surface above a vertical reference (typically the
  WGS84 ellipsoid or a regional geoid). The atomic topography concept
  that slope, aspect, hillshade, TPI, TRI, and curvature derive from.
  Flagship products: Copernicus DEM GLO-30/90, USGS 3DEP, AW3D30,
  ASTER GDEM v3, NASADEM. DSM and DTM are sub-concepts capturing the
  surface-including-features vs bare-earth distinction.
