We have been using google earth
for the past few years as an additional source for navigation
. In fact this has led us to tuck into numerous places in the Sea of Cortez
that are not in any guide books
. Using it when not connected to the internet
and a GPS
interface has been the closest thing to real time that we have seen. But with that said like all navigation
you better have your eyes open as well. In addition now openCPN
has a GE add on it makes it that much better. Lastly the GEKAP program allows you to make charts
from GE screen
shots. Fantastic stuff.
Certain areas are only passed over by GE at a much higher altitude thus missing some of the detail.
