Standards for Hydrographic Surveys

6 Data Processing

6.1 Data verification

All calculations must be verified and counter-signed by an experienced hydrographer before the results can be used to further the acquisition of hydrographic data. The bathymetric data must be processed as soon as possible after it has been collected to analyse and verify the work.

Processing best practise is outlined in the document “CUBE Bathymetric data Processing and Analysis (CHS February 2012)”.

6.2 Data codification and presentation

All data must be coded using the most recent version of CHS coding and presentation standards, otherwise, data must be separated into layers and a comprehensive layering documentation must be included as metadata information or in a final report including all pertinent information that may help CHS to qualify the data better.
