Njord

Status: This project is still very much a WORK IN PROGRESS.

Live Demo: https://openenc.com

Marine Electronic Navigational Chart (ENC) Server

Njord consumes S-57 IHO transfer standard for digital hydrographic data. S-57 format chart data is published by hydrographic offices such as NOAA. https://www.charts.noaa.gov/ENCs/ENCs.shtml

Njord displays ENC charts but does NOT strictly follow the IHO S-52 specifications for chart content and display.

S-52 display and S-57 data standards can be found here: https://iho.int/en/standards-and-specifications
