We use a program called GE2Kap which allows you to make charts
from Google Earth screen
shots which can then be loaded into Opencpn
like any other chart. In places where electronic charts
are off by as much as a 1/2 mile they are invaluable. We have used these charts almost exclusively for all our close in navigation
and are now making them for Vanuatu
, our next destination
. Since we have so many loaded in some areas it can get confusing which chart to open. The plug
in allows you to cursor over the exact chart that you want to open.
You don't use an internet
connection to use the charts in Opencpn
. They are loaded onto your hard drive by GE2Kap after they are made and are available offline. You must have an internet connection to Google
Earth in conjunction with GE2kap to make the charts however.
