ECDIS Route Converter Online | RTZ, Transas RT3, GPX, BVS

Q: How do I import the exported file into Furuno or JRC ECDIS?

Export your passage as an RTZ (.rtz) file, save it to a USB drive, and import it via the IEC 61174 Route Exchange option on your ECDIS.

Q: Is voyage or vessel data stored on external servers?

No. The application runs 100% client-side in the browser. Route data is never uploaded to any server.

Universal ECDIS Route & Passage Plan Format Converter

The NavLib ECDIS Route Converter is an engineering-grade web utility created for Deck Officers, Shipmasters, and Marine Pilots[cite: 1, 3]. It resolves proprietary format restrictions between marine bridge consoles, performing real-time transformation of Waypoint coordinates, Cross Track Limits (XTD Port/Starboard), Turn Radii, and steering geometries.

Built on a zero-server client-side architecture, all file parsing, XML serialization, and coordinate calculations run strictly inside your browser memory without uploading sensitive ship routes over the internet.

Supported Hardware & Exchange Formats

🌐 RTZ International Standard (IEC 61174) Official IMO Route Exchange XML format. Directly supported by modern Furuno (FMD-3100/3200/3300), JRC (JAN-7201/9201), Wärtsilä Navi-Sailor, Sperry Marine VisionMaster FT, and Raytheon Anschütz.

🖥️ Transas, Danelec, MARIS & Totem Full support for Transas RT3 (.rt3, .txt), Danelec Marine ECDIS (.xml), MARIS ECDIS900 (.rou), and Totem Plus (.tot) proprietary files.

🌦️ StormGeo Bon Voyage System (BVS) Import weather-optimized ocean tracks from StormGeo BVS (.bvs / ASCII) to convert them into bridge-ready ECDIS passage plans.

📱 GPX, Google Earth KML & Nautical CSV Generate files for GPS units, visual inspection in Google Earth, and Excel passage tables. The intelligent regex engine extracts coordinates (DMM, DMS, DD) directly from plain emails.

Geodetic Computation Engine

Calculations of True Course (TC) and Leg Distance follow the WGS-84 ellipsoid standard. Navigators can toggle individual leg legs between Rhumb Line (RL) and Great Circle (GC) with live orthodromic curved geometry rendered on the Leaflet chart preview. The «Reverse Route» function recalculates bearing angles across all legs for return passages in a single click.

ECDIS Route Exchange FAQ

How do I import the exported file into Furuno or JRC ECDIS?

Select the RTZ (.rtz) export option, copy the file onto a bridge-approved USB drive, and use the standard «Import Route» (IEC 61174 Route Exchange) function in your ECDIS route planning menu.

Is voyage or vessel data stored on external servers?

No. The application runs 100% client-side via JavaScript FileReader and DOMParser APIs. No waypoint details, passage notes, or vessel routes are transmitted over network connections.

OPERATIONAL SAFETY NOTICE: This application is intended solely as an advisory planning utility. In compliance with SOLAS Chapter V Regulation 34 and IMO Resolution A.893(21), the Officer of the Watch and Master must perform full waypoint validation and a safety check on the certified bridge ECDIS prior to voyage execution.
