internet "Google Earth" cannot load new maps, but the former visited
maps stay in the computer.
The GPS reception works all over the world
and is independent of the internet. GPS is an independent system.
Pure web applications (like Virtual
Earth and Google Maps) loose their maps without internet
connection. Not as "Google Earth" - it remembers images and maps once
shown in the screen in its so called Cache memory. As long as this cache
is'nt full all recently "overflown" Areas are still available.
If you revise calmly at home all interesting
areas (you plan to visit on a tour) in "Google Earth" with an active
internet conmection, all this maps stay available in "Google Earth" even after
disconnecting the internet. Now you may take the Latop into the car or on the
boat and will have all necessary maps "in the bag". For the GPS navigation
internet itself is'nt yet necessary.
Now also with Cache Manager
In the new version 3 the tool "Cache for Google Earth" is entirely integrated into
"GPS for Google Earth" - without surcharge. This gives you the oppotunity to manage
different offline maps stocks. It's no longer a blind chance, when Google Earth
deletes older maps cause of a full cache. In fact you may exchange offline cache
copies with other computers.
