Calhypso, a solution for cartographic and hydrographic services
One of main tasks of cartographers is processing bathymetric data to convert it into navigational charts (or ENCs). 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 ENCs automatically.

Creation of ENC charts
Creation of generalised bathymetric charts from high density bathymetric data (.xyz; .lgz; .glz; .pts; .csar files).
Control of the sounding selection to ensure that the result 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.
Detection of new dangers to navigation
Comparison of new bathymetric data with an existing ENC to identify discrepancies and warn mariners of new hazards.
Updating ENC from new survey dataset
DEPARE geometries creation and sounding selection to update ENC inside the data extent.
Merging new ENC geometries with old ones.
Chart ajustments applied near the data boundary to get a uniform update result.
How do you produce and update bathymetric navigation charts?
A service dedicated to hydrographic and cartographic solutions for producing and updating bathymetric navigation charts. Calhypso includes validation tools in addition to its main ENC creation functionality. In this way, the software helps to control and update charts using the most recent bathymetric surveys.

An automated tool able to compare a new survey dataset (.xyz, .lgz, .glz, .csar) with a reference ENC catalog.
Step 1 : Import xyz dataset
Step 2 : Specify ENC directory
Step 3 : Add optional filterings and launch process
Step 4 : 2 ENC intersect the survey, the comparison wtith the first ENC is achieved, the comparison wtith the second ENC is achieved
Step 5 : Output results
Step 6 : 2 intersected ENC, Calhypso Detect sorts deviations into 3 severity files
Calhypso Detect highlights every data sounding with a significant gap from reference ENC as defined by B-620 section of S-4 IHO standard.
Calhypso Detect identifies soundings to add and isoline sections to update.
Calhypso Detect can process high-density datasets in few minutes.
