You can transfer way points from Google Earth to your electronics, if that is what your asking?

See if this video will help.

I've tried it, and it doesn't work.
From what I found out Google, Bing Maps, etc., do not use GCS on WGS 1984 which are references in an unprojected graticule, rather they use "web" Mercator projection onto a spherical globe, notated in ArcGIS as WGS 1984 Web Mercator (Auxiliary Sphere).

Yes; well you're not adding it to Navionics, but you are adding an additional base layer to your Lowrance/Bird/Raymarine unit.

I use Google Earth Paths to indicate creek channels, and shorelines at lower water levels. They are converted to Humminbird Tracks and go in the unit's waypoint library. They are not Navionics map edits.

This is some of the shoreline at a water level 12' lower than normal pool and before any map company had a shoreline for it. I only did major features:



Same tracks after Navionics added the shoreline to their base map:

Doing the same thing, I did the shoreline of a 420 acre lake before there was any mapping available. Needed a shoreline for waypoint reference.



After I did this, I found out I made a digit error in entering waypoints that I created using a hand held GPS unit when the water level was about 15' low. Had to move +Hr5 over to the lake.

You need to change the last four google earth coordinates . Ex. Ends in 25.56 divide this by 60 =.426. This is the last three you plug into your gps. This works. I'm sure there is an easier way. Create a spreadsheet to expedite the process.
