About RTZ Route Exchange (.rtz)

RTZ is the maritime route exchange format standardised as IEC 61174 (ECDIS) and published by CIRM: an XML route of waypoints with latitude/longitude, turn radii, cross-track limits, leg speeds and an optional schedule of arrival times. RouteConverter reads both the 1.0 and 1.1 namespaces. Read and written by ECDIS bridge systems and voyage-planning software; the zipped .rtzp package variant, which bundles attachments, is not supported.

About GPX (.gpx)

GPX (GPS Exchange Format) is an open XML format for waypoints, tracks and routes, with optional time, elevation and extension fields. It's the universal GPS interchange format — read and written by Garmin Connect, Google Earth, OsmAnd, Strava, komoot and nearly every GPS app or device made since 2004.
