More on Do It Yourself charts from Google Earth

by Nancy Knudsen on 15 Jan 2012
Google Earth CAN give you accurate charts .. .
In November we published an http://www.sail-world.com/index_d.cfm?nid=91281!article_by_Paul_Higgins, showing cruisers how to create your own charts from Google Earth, meaning that there should be no inaccuracies as there are with 'normal' charts. If that didn't do it for you, we now offer another method, provided by long-term cruisers Eric and Sherrell on Sarana.

The value of having totally reliable charts cannot be underestimated, as many a cruiser will tell you who has found themselves anchored on a sandbank (according to the chart.)


Eric and Sherrell have been cruising since 1996 on Sarana, a Mariah 31. They are both ex-corporate types who feel now that they never really fit in well, but they admit they were at one time very dedicated to the corporate cause.

They say, 'We love to travel and we have been all over the world the fast way, now we are going to see everything at 6mph.'

Now Eric writes the following for http://groups.yahoo.com/group/Cruisers_Network_Online/!Cruisers_Network_online:

For those of you who have been frustrated by inaccurate charts that place islands and coastlines miles off their GPS positions and would like to use Google Earth's images in your chart plotter for higher accuracy, I've written a procedure that will help you import them as a BSB/KAP image. Not only can you create your own charts, but the procedure works for any PNG/TIFF/BMP type image that you might want to make into a chart. So now you can use a free chart plotter tool like OpenCPN and make your own charts.

This procedure should work on both Linux and Windows systems easily. In addition Mac users should be able to slightly modify the instructions and be able to make charts as well.

Please see the following link for more details http://www.sailsarana.com/make_charts_from_google_earth.php

Comments and feed back are welcome on the website.


Yet Eric and Sherrell are not just pretty faces of cruising and authors of handy instructions. If you ever find yourself in Central America, take a look at their guide books for the Pacific Coast of Central America:

AND they also have several free guide books too that might interest you, http://www.sailsarana.com/free_guides.php covering Pacific Colombia and other far-flung places.

Low DSC connect rate-Sailor irresponsibility or technological failure?
Is the low take-up of available DSC connection to radio because of sailor irresponsibility, or is it more complex? Recently we published a story about how few yachts had their Digital Selective Calling (DSC) equipped VHF radio connected to their GPS so that their position would be recorded in an emergency. The tone of the article suggested that the low take-up was an indication of the irresponsibility of sailors, but responses to Sail-World after the article suggest that the situation is more complex than this

Sailor's aid or sailor's nightmare - the tides explained
It's not surprising if you don't exactly understand tides - it took a lot of figuring out over the ages As sailors, we all know that tides come twice a day, vary according to the moon, and, depending on where you are sailing are either unimportant, reasonably important, or critically important to a successful completion of your voyage. But why the moon? and if the moon only circles the earth once a day, why are there two tides? Here, Grant Headifen of Nauticed, explains
