Can Navionics maps be downloaded on

an iMac and overlayed on Google Earth?

There's a Navionics app available for Android and IOS - they don't have a Windows or Mac version. it's proprietary data and only available in a portable form a few ways

 

On a fishfinder that supports Navionics data.

On an Android or IOS device running the app.

On any device using the website.

 

Don't know of any way to get the Navionics data to overlay on Google Earth - though the Navionics maps do show roads, towns and launch ramps.

when you say overlaid with google earth, do you mean for the land based items or for seeing the google earth water photo with depth lines on it?  The navionics website will take care of the first.  I don't know a way to do the second.

@OldBlueEyes can you explain why you need to do this?  What's the goal?

The goal is to place a contour map over

Google Earth so that when I locate

a spot that I want to fish, Google Earth

will give me the GPS coordinates.

 

I’ve done this with NOAA maps, but they

are quite old, in many cases lack detail,

and are no longer accurate because of

their age.

 

I was hoping that Navionics maps might be

more up-to-date.

Two things:

If you use SonarChart, maps are updated constantly by users.  It's in the lower right.

If you use the mobile Boating app, you can get the GPS coordinates.

 

 

Unfortunately, I don’t have SonarChart –

just a Lowrance Depth Finder.

 

Thanks for the information.

on the free navionics website you can choose sonar chart or navionics mapping. It’s one of the map options.

If you have a tablet or smart-phone, you can run the app on that.

 

My Garmin is a Striker - no built in maps...so I have the app running on my 8" Galaxy Tab. With the GPS active on the tablet, I basically have the mapping that the Echomaps have.

I'm pretty sure newer Mac computers can run ios apps. Check the app store.
