Welcome to the EarthNC Trip and Route Tool User Guide

The Trip and Route Tool (TRT) lets you create trip and route plans in Google Earth and easily export them to GPX file format for use with stand-alone GPS devices. In the case of Garmin USB GPS units, you can send your trips and routes directly to the GPS using the EarthNC TRT through use of the Garmin Communicator API.

While the EarthNC TRT is designed for use with EarthNC Plus, EarthNC Raster, and EarthNC Online marine charts, the Trip and Route Tool can be used for any type of Google Earth planning.
