WorldDEM is a product of the TanDEM-X mission
This is a joint mission (PPP) between Airbus Defence and Space and the German
government (represented by the DLR)
The mission used the resources of both the TerraSAR-X satellite and the TanDEM-X satellite
2 virtually identical satellites, orbiting in a close formation, were required to create the
synthetic aperture radar antenna, which was required to measure elevations on a global scale
Responsibilities
Airbus DS manufactured both satellites
DLR launched and maintains both satellites
DLR acquired the raw data and undertakes the interferometric processing and mosaicking
Airbus DS undertakes the DSM hydrological production and DTM production and data QC
Distribution
DLR distributes the TanDEM-X DEM to research and scientific organizations
Airbus distributes the WorldDEM DSM and DTM on a commercial basis

The Integrated TanDEM-X Processor (ITP)
The ITP ingests and screens the incoming acquisitions, focuses the individual scenes in
parallel to resampled complex images, calculates the filtered interferogram, performs the
phase unwrapping and height pre-calibration for accurate phase-to-height conversion and
finally generates the geocoded raw DEMs.
ITP is essentially an automatic process, with little human intervention
The Mosaicking and Calibration Processor (MCP)
DEM calibration requires a global set of suitable height references. For TanDEM-X ICESat
data are used as ground control points. A small subset of selected ICESat points is used for
calibration, and the remaining majority is used for validation of the final DEM heights.
In MCP, the calibration corrections are applied to each DEM and different coverages are
mosaicked by a weighted average of all elevation values at a given position.
Detailed TanDEM-X processing information is available at:

Terrain (Surface) and Water Artefacts
Terrain Artefacts can be divided into two general categories:
1. Artefacts where no valid height information is returned (void or noise)
This is a random error
2. Artefacts where the height information returned is not valid (cycle-shift or phase
unwrapping)
This is a systematic error
Water Artefacts are also found in two categories
1. Extreme noise caused by little or no signal return from water
2. Void (no height information) caused by no elevations returned during processing

Integrated WorldDEM Production Tool: DEMES
IGTF 2016
23
Airbus DS has developed a bespoke software package to create WorldDEM
Very specific tools required – especially for Terrain editing
High volume of data – up to 150 million km2
While commercial GIS/mapping tools can do some of the processing steps, none
of them can really do it in an integrated fashion
DEMES allows the efficient production of WorldDEM on a global scale
Workstation-based editing tool
Server-based data management system

WorldDEM Production Process and Effort
Incoming Quality Control
Checks the completeness and statistical quality of the data
Terrain Editing
Identify and correct terrain artefacts
Hydrological Editing
Identify Hydrological features and set their elevation correctly
Final Quality Control
Automatic and visual inspection to ensure conformity to WorldDEM standards
Assumptions
Terrain Editing – 20% of effort
Hydrological editing – 80% of effort

Terrain Editing Process
IGTF 2016
25
Generate Reliability Mask (automatic process)
Every pixel (height measurement) is checked
Generate the Feature Mask (semi-automatic process)
Tile-wise or smaller AOI can be selected
Edit Resulting Artefact Classes
Small Artefacts: Interpolate
Medium artefacts: Smooth
Large Artefacts: Infill using Delta-surface algorithm
Check Geocell for Offsets
If Offset is considered valid, infilling (DSF) is usually the correct remedy

1. Height error mask (HEM) – represent the height error in form of
the standard deviation
– derived from interferometric coherence
and geometrical consideration
– considered to be a random error
2. Digital elevation model (DEM)
3. Consistency mask (COM) – indicates DEM pixels that have height
inconsistencies between different DEM acquisitions
– Distinction between …
– Large absolute height inconsistencies
(e.g. phase unwrapping errors, incoherent areas
like water bodies, shadows, layovers)
– Small absolute height inconsistencies
(e.g. temporal changes)

• Concept: Multi-scale analysis of local noise level (i.e. DEM uncertainty)
Results with very small kernel size
– Stddev 3x3 as description for the local DEM uncertainty

Geomorphological & hydrological impact in human and natural environment
• loss of soil to the sea
• Increase of saltwater intrusion (e.g. danger of drinking water reservoirs in coastal areas)
• Increase of storm surges, frequency of cyclones and floodings
Quality of Elevation Reference is decisive in Flood and Sea Level Rise modelling.

Case Study: Seismic Hazard Mapping
Study:
Search for landscape expression of pre-historic
surface rupturing earthquakes
Result:
Identification of fault scarps in WorldDEMTM data of 5
m high and up to 10-15 km long.
“I am impressed by the WorldDEMTM data in terms of
resolution compared to other available datasets.
It is useful for regional reconnaissance and for feature
characterisation (…)”
