IQMULUS – BIG GEO DATA
• 4 year EU FP7 Research Project (8.1 Mio EUR)
• A High-volume Fusion and Analysis Platform for Geospatial Point Clouds, Coverages and Volumetric Data Sets
• IQmulus will leverage the information hidden in large heterogeneous geospatial data sets and make them a practical choice to support reliable decision making

SAND DUNE DISPLACEMENTS
Motivation
Detection of sand dune displacements by comparing bathymetricsurvey data from different points in time.
Submarine dunes and sand banks are among the most dynamic geomorphologic formations in coastal waters. Their movement can have significant impacts on the benthic ecosystem, marine transport in coastal waters, and infrastructure such as pipelines and communication cables.
Standard for the analysis of multi-temporal MBES surveys is visual analysis by trained experts delineating the crest line of the dunes at several time steps
