Storing Google Earth Cache Data?

[crusader]

Finished reading Chris Marzonie's review of different GPS mapping software in the latest Overland Journal a few days ago. Till then, I never knew that Google Earth could be used offline in conjunction with GooPs for real time photo mapping/tracking. Pretty cool and works like a charm. With maybe one excpetion, that is...

Background: In order to have detailed, non-blurry photos when using Google Earth as a moving map, you either 1) have to be connected to the internet so Google Earth can continuously fetch the detailed images or 2) pre-fly the route at home, while connected to the internet so that the images along your anticipated path can be stored in a memory chache and a hard disk cache.

My problem is that when I pre-fly the route, then drive it tracking in Google Earth, the photos are detailed, but when I turn off the computer and turn it back on later to return home along the same route, I get the blurry, non-detailed images.


My Questions:

1) Are you required to pre-fly the route every time you turn the computer off and back on? What about the DISK CACHE?? Isn't that supposed to be a little more...permanent, at leat till you exceed your allotted disk space with new images?

2) Is there a way to pre-fly different routes and store them on a memory card or memory stick so that you can load the route to the disk cache whenever you need instead of having to pre-fly the route anew every time? Sort of a library of different cached routes...?

Thanks!

You might need to increase the cache by going to Tools->Options and select the “Cache” tab. You can make the cache size up to 2000 MB. If this still does not give you the cached information you are looking for, you need to look at which layers you have open. Remember, that every Google layer (for example, ‘roads’ or ‘dining’) that you have open is also cached and taking up valuable space. It doesn’t take much time to fill up the cache, especially if the area you are viewing has a lot of high-res images. If you are running out of cache space, the current work around for the issue is you can save your cache(s) under different files and then swap them out to look at different areas. This is useful if you are traveling without internet access for a prolonged period of time.

I admit to being kind of lazy on this--I posted here hoping somebody would already have all the answers, saving me from having to do the research. but...I've got the cache size maxed out. The capacity isn't the problem--I only had 17 miles of image data (with no overlay junk) in the cache. The problem isn't that I ran out of space, it's that when I returned home after work, Google Earth forgot everything I taught it earler in the day.

Storing the cache file under another name till I'm ready to re-use it is exactly what I want to do. Problem is, I don't know the name of the file that Google Earth uses to cache it's data. Of course, I never really looked at the directory(ies), either (see laziness admission above). I'll have a peek. Perhaps Google set it up using the word "cache" or something obvious somewhere in the file name...

EDIT: They didn't.

Has anyone actually got this to work in the last 4 months? I tried this Google Earth setup with Goops earlier this year and could not get it to work. I was lead to believe that Google intentionally changed Google Earth so that once you shut down Google Earth the cached pictures were no longer available.

I guess I will need to read the article in Overland Journal this weekend.

Google Earth Cache data is at C:\Documents and Settings\username\Local Settings\Application Data\Google\GoogleEarth
(where username is your Windows Username)
The files are dbCache.dat and dbCache.dat.index
