Compétences visées

Learning Outcomes:

To be able to create the required data types, part of a standard exchange format and to configure systems for secure storage, transfer and backup of survey data.

Applying procedures used to assess, accept and reject data.
Being able to apply spatial data processing techniques to create DTMs or gridded surfaces and contouring, as well as applying estimation procedures to assess survey measurements and volume computations.
To explain the concepts of Spatial Data Infrastructures (SDIs); raster and vector data models.
To be able to use file types that support the exchange of hydrographic data to transfer data between acquisition, database and GIS environments.
Explain the concept and use of GIS within the marine environment.
