One of the most time-consuming tasks for cartographers is processing bathymetric data to convert it into navigational charts (or bENCs). The cartographic synthesis of water depth data is a painstaking and time-consuming task, and is affected by a concern for uniformity and accuracy. Calhypso, the result of a project designed to address these issues, is a software package that processes bathymetric files and produces bENCs automatically.
Creation of bathymetric charts in IHO S-57 format using parameters including the scale of the chart.
Control of generalisation to facilitate the work of cartographers
Identifying new hazards to navigation by analysing and comparing charts in use and more recent bathymetric surveys.
Creation of generalised bathymetric charts from highdensity bathymetric data (.xyz; .acs; .csv; .dat; .lgz; .glz; .pts files).
Control of the generalisation by comparing the input file with the result to ensure that the latter meets the security and legibility requirements of cartographers.
High-quality generalisation frees the cartographer from repetitive tasks and makes it easier to analyse complex cases.
Comparison of new bathymetric data with an existing ENC to identify discrepancies and warn mariners of new hazards.
Automatic detection of hazards to navigation.
