  • Coastline map creation with aerial photographs 
  • The use of Ground photography in the depiction of coastline topography 
  • Relation between tidal datums and charted shorelines 

  • Required hydrographic data for navigational publications (including tide tables, sailing directions, light lists, radio aids to navigation, port guides, and notice to Mariners) 

  • The process of creating chart plates from graphic products and from digital files 
  • Production of the Chart out of multiple plates 
From digital data to digital maps (on nautical devices and on the web) 

  • The importance of updating nautical charts and the dissemination of chart corrections 
  • The responsibilities of each element in the sequence from surveyor to mariner 
  •  Obtaining latest information and checking for old data 

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. 
  • To be able to use data cleaning techniques using appropriate software, while distinguishing between noise, outliers and real features as well as assessing propagated errors 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.

Modalité d'évaluation

Evaluation form  
Written examination, partly with multiple choice, partly with open questions. 
Fieldwork – permanent evaluation of the practical exercises 
Assessment methodology 
The final figure of assessment is composed of: 
50% (written examination) 
50% (permanent evaluation) 
Assessment criteria 
Permanent evaluation: this evaluation is based upon the training record book in relation to the number of tasks carried out and the comments of the supervisor(s) expressed in written in the book; workshops: proof of attendance: reports, exercises. 
Theory examination: quality of knowledge, insight, relation between subjects, …
