S-101 ENC
Chart portrayal with the full mariner parameter set and display palettes, updating, display modes, orientation, chart furniture and pick reports.
In active development
Next-Generation Maritime
Software for the S-100 Era
We build the blocks your maritime systems are made of, starting with a strict-conformance S-100 chart engine. Ready-made libraries, product development and consulting for the companies building navigation systems.
Status
The chart engine is in active development and this site is growing alongside it.
Early discussions with maritime software companies, equipment manufacturers and
integration partners are welcome -
get in touch.
S-102 Bathymetry
Gridded surfaces with the Enhanced Safety Contour and depth substitution into ENC soundings.
S-104 Water Level
Water level adjustment in both standard forms, flowing into display, pick reports and safety checks.
S-111 Surface Currents
Current arrows with record selection and an optional speed legend, suppressing overlapping ENC symbology.
S-124 Nav Warnings
GML datasets and delta updates, cancellation, and highlight of the areas a warning affects.
S-128 Product Catalogue
Per-product up-to-date verdicts against installed holdings, and the four-week receipt clock.
S-129 Under-Keel Clearance
Display of under-keel clearance plan datasets, for the routes that need them.
Coming soon
S-57 Dual Fuel
Legacy S-57 ENCs displayed alongside S-100 products in the same system, for as long as both are in service.
Our products
Built on our framework
S-100 Chart Engine
Seven S-100 based products are integrated and displayed together. Our framework is delivered as C++ libraries with a Qt-based API. The S-100 Viewer is the reference client, built on top of it, shown here.
What the engine covers →
S-57 to S-101 Converter
Converts an S-57 portfolio to conformant S-101 exchange sets per IHO S-65 Annex B, with every decision reported against the clause behind it.
About the converter →Chart imagery rendered by our S-100 chart engine. Source data: NOAA Office of Coast Survey, retrieved from the NOAA Open Data Dissemination programme, August 2026. S-101 converted by EC Consulting from NOAA S-57 under IHO S-65 Annex B: derived data, not an official NOAA product. Not for navigation.
Foundations for Your Systems
We build components for your maritime applications. Our libraries are made to sit inside your product and carry the parts you would rather not build twice.
Standards Focused
Aligned with the S-100 framework and IHO standards.
One Framework
Our products share an architecture, so the pieces fit each other.
Future Ready
Continuously evolving to support emerging S-100 products.
In development
Where the project stands today
The S-100 chart engine is the first product and the current focus. It is well advanced and currently in testing, with the S-164 conformance work under way.
Planned beyond it: a wider maritime framework sharing the same architecture, with libraries for NMEA, AIS, tracked targets, routes, own ship and past track, navigation tools, and a consolidated set of simulator applications for development and testing. Alongside the products we take on product development and consulting for customers building their own systems.
