Has anybody linked up Google earth with a chart plotter?

Not a standalone plotter, but the Navionics app on iPhone and iPad has a mode in which it shows chart data below the high-water mark and Google Maps satellite pictures above it. It does need a phone signal to do the Google Maps part of that.

Bear in mind that Google Earth and WGS84 coordinates are not compatible. Here's an image of DGPS plots overlaid on a straight Google Earth Image and the same plots overlaid on a manipulated Google Earth image.

Google Earth needs a continuous internet connection though does it not?

No, there's a way round it. Before leaving you can zoom into your rough route and anchorages in GE and it will save the images in the cache or there are programs free on the net which will do this for you if you input your route. Never tried those but the zooming in works. Can be a very useful addition.

Thanks, that is very useful so another little job to do!

Give it a go, it's nice to have the choice. :) I really like having the option, in google earth itself as well the 3d view can help a lot seeing which headland or hill is which. You can always ignore it if you want to. ;)

It's still telling me I'm in Loch Fyne .. so Inveraray should be just be a little to the North then :(


OK, let's have a look at Staffa : http://g.co/maps/8w9d4

Nope, still not convinced.

I have a new LG android base phone with built in Wifi, GPS and Google maps. It enables me to download and cache areas that I will be visiting while I have internet access, then the built in maps programme will use the gps and appropriate cached maps/sattelite pics when offline.

I've only used it for walking, in car and inland waterways so far, but the accuracy is very good and the 90x55mm screen big enough for serious use. I believe that there are charts available but haven't looked yet.

While in Andalucia recently, I was able to download maps for all the areas we were visiting via local wifi and used it to great effect.

Not using a plotter, but using Fugawi Navigation on PC. When we lived in central Europe, there were no road Nav systems for places like Slovakia at the time, so downloaded Google maps Satelite pictures with Lat Long co-ordinates to allow me to triangulate using Fugawi's option for scanned maps. Took about 10 mins! Then used on laptop to drive into Bratislava right up to front door of hotel! Incredibly accurate, but not tried at sea yet.

VisiCharts run in Google Earth

Hi All,

Someone kindly mentioned our VisiCharts, not here to promote them, just Google VisiCharts to find out more.

They are basically UKHO raster chart images in .kmz format. They overlay themselves over the satellite imagery, with variable transparency.

Sold plenty of these chart sets now, and had plenty of feedback too. Users like to use them for planning while at home (with fast internet connection), then use conventional plotter (like SeaClear) when at sea.

What we've found remarkable is how the images and charts lock together, right down to pontoon level in most cases. Also interesting is that the charts are normally far more up to date than the satellite imagery.

Trouble is GE is not really set up for passage planning or sea work, but as mentioned, GE will cache 2 Gb of imagery for offline use with the VisiCharts which are held on your local machine.

Other interesting thing is how the charts of differing scales will quilt themselves together.

Long way to go with this technology yet, but don't be surprised if the GE .kml/.kmz format becomes more standard on chart plotters in future. I know Coastal Explorer is offering .kml support soon. If Open CPN could use .kml/.kmz chart formats we could make legal charts for that too.
