WorldDEM™ Thematic Layers and Derivatives

Elevation Model of choice for all global applications

Integrating WorldDEM™ as a reliable and precise reference layer into operations and applications provides for a single confidence scale and enhances the performance of a wide range of systems and equipment.


Most consistent, homogenous and accurate Elevation Model for high-quality image orthorectification on a Global Scale

  • An elevation information layer optimised for the orthorectification of high-resolution (HR) and very high resolution (VHR) optical satellite data
  • Global off-the-shelf availability
  • Available in large areas (global, continent, DRS cone, country)
  • A single-source Digital Elevation Model, automatically produced, 24m posting, based on the WorldDEMcore (smoothing, filtering and filling depending on terrain and land use)
  • Ensures that the orthorectified image is free of artefacts
  • Minimises distortions in the orthorectified image induced by the topography of the landscape
  • Ideally suited for DRS and satellite operators and anyone wishing to orthorectify their imagery

WorldDEM DTMlite

Most accurate Digital Terrain Model (DTM) on a Global Scale

  • Automatically generated Digital Terrain Model (DTM) meeting basic quality requirements
  • Bare Earth: man-made objects and vegetation are removed
  • Consistent and uniform resolution of 24m
  • WorldDEM DTMlite profits from the high precision of the WorldDEMTM product which serves as input to the automated process
  • Closes gaps in the market between LiDAR and existing large area elevation models
  • Available globally off-the-shelf

WorldDEM Ocean Shoreline

Homogeneous, gap-free and single-source shoreline mapping

  • Replacing GSHHS (Global Self-consistent, Hierarchical, High-resolution Shoreline Database)
  • Delineation of the shoreline derived from global WorldDEM dataset (vectorised)
  • Representing the water-land-mark at the time of data collection
  • Consistent and uniform resolution of 12m: vectors without any topological errors or gaps
  • Including river mouths on ocean level (zero elevation)
  • Using the latest available satellite imagery further enhances the shoreline to account for any recent temporal changes (new ports, marinas, jetties, breakwaters, beach erosion or accretion)
  • Update possible with TerraSAR-X or other satellite data as required e.g. after a tsunami event

WorldDEM Hydro Layer

High resolution hydrological mapping & modelling

  • Homogeneous and accurate information on a global scale
  • For regional and global analysis and modelling (map scale 1:25,000)
  • Contains vector data of lakes and rivers derived from the WorldDEM amplitude data
  • Optional: vector data of stream lines (drainage network) derived from the WorldDEM elevation data
  • Replacing existing standard (SWBD - SRTM Water Body Data)

WorldDEM Clutter Map

Development and planning of mobile network infrastructure

  • Bundle of WorldDEM elevation data clutter map
  • High resolution (24m pixel spacing)
  • Globally available
  • Off-the-shelf delivery / On-demand
  • The clutter map, delivered together with a WorldDEM 24m product, shows the physical coverage of the Earth’s surface, divided into several land cover classes. It is a composite of the medium resolution Land Cover Map provided by the European Copernicus Global Land Service and high resolution feature classes mapped by Airbus.
