This is a little more information on Fugawi Marine 4.5.
has an experimental (beta) option for displaying a split-screen display of a GPS
position synchronized image from Google Earth
. There are several problems. The display has some erratic behavior, centering doesn't work properly and the program doesn't function if the map data are not already in Google's cache or if there isn't an active Internet
connection. The latter functionality could be by Wi-Fi, cellular,satellite or other radio
communication link with the Internet
One alternative is to manually select overlapping, high definition Google Earth images
along a route
of interest prior to navigating the route
automatically stores the image data in a cache file and will use this information, if available, rather than having to repeatedly download it from the Internet. The maximum size of the cache is 2 GB. You can save the data in another file and then copy it back to Google's cache whenever you want Google
Earth to use it. The only catch is that the Google Earth program periodically sends out a nag message indicating that it cannot connect to the Internet even when this connection is unnecessary because the required image data are already locally accessible.
