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.

WorldDEM™ Thematic Layers and Derivatives
Elevation Model of choice for all global applications
WorldDEM4Ortho
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.
