EU-Hydro/EUDEM – Updating the model and cartography for the “European Environment Agency” in collaboration with INDRA
Client: European Environment Agency in collaboration with INDRA
Correcting geopositioning issues.
New data for EU-DEM North of 60˚N – the major upgrade task.
Ensuring consistency with EU-Hydro i.e. coastline and water bodies.
ICESat bias adjustment – from the statistical validation follows that the bias seems to be highest in the regions where the control points for EU-DEM vertical adjustment was not available i.e. UK and Nordic countries (excl. Denmark) and most of Eastern Europe (cf. page 36 in GSGRDA-PR-021 EU-DEM/EU-Hydro technical documentation). Thus a vertical control with ICESat in these part could make sense.
Screening for artefacts.
Improved hydro-forcing to produce better river network topology.
Taking stock for further improvement of EU-DEM south of 60˚N by ingesting SRTM new version in EU-DEM.
