Hydrographic data management comprises data processing and is presented together with professional software tools, like CARIS HIPS/SIPS. The module includes the concepts of GIS, and practicals make uses of the freeware QGIS.
- Raw data and acquisition systems;
- Hydrographic data processing principle;
- Single and multibeam echosounder system data processing;
- Side scan sonar imagery;
- Hydrographic data format, data exchange and nautical charts.
The main learning outcomes of HDM are:
- To process swath echo-sounder systems data from raw data to digital terrain models, in particular to be able to detect systematic errors, and apply data quality assessment methods
- To process SBES data, apply interpolation methods and evaluate DTM uncertainty
- To process (compensation, mosaics) side-scan sonar and interpret side-scan images
- To integrate survey data into a GIS, structure survey data, and manage metadata. Produce minutes of bathymetry
