EarthBridge Without Internet...?

Have been fiddling with Earthbridge and find the interface to be intriguing!

Is there a method of saving relative map portions from Google Earth onto a memory storage device, USB stick or even the hard drive. I know that Google Earth maps are HUGE, and measured in the terabyte realm, but I'm wondering only of a radius from a given point? A city, perhaps?

Would this allow the interface to function if no internet connection was present? Has anyone tried this?

I have not spent much time with Earthbridge so I do not know what the possibilities are.

I have spent some time messing with Google Earth and in the free version you can load the disk cache with map data by simply browsing the area(s) of interest. Google Earth's disk cache will store the most recent 2GB of data.

To put that into perspective, I recently made a 3,000km loop across Southern Alberta into SE British Columbia and back home through Banff and Calgary. Before I left I browsed the entire loop in Google Earth, in many areas zooming in for maximum detail.

Before I started to load the cache I cleared it. When I had messed around to my satisfaction and felt I had way more than I needed I had way less than 2GB in the cache. I can't recall exactly but it seems to me it was around 700MB.

I hope that helps.
