Please note that height above the ground is NOT the same as eye height!
To give a rough idea about the area coverage:

height(m) Area(km2)
400 600
600 1400
1000 4000
2000 15000
3000 35000
4000 62000
5000 97000

Coverage also depends on your GE settings for layers and so on.

I derived an empiric formula to roughly calculate the total area covered for a given height to fill the maximum GE cache of 2000 MB. This formula works well for heights between 500 and 5000 meters, probably the most used.

A = (H/16)^2

A = area covered in km2
H = height above the ground in meters

No, I don’t know where the GE plugin keeps its cache; sorry.

Thanks for the quick reply Leszek
Do you know where the GE Plug-In cache lives?

The Google Earth plugin does cache data, but unfortunately it flushes the cache automatically when it closes. So none of these techniques will work with it.

Hi Leszek:
I’ve been a reader of your site for some time now and always enjoy you posts.
I found your latest series of posts on Google Earth caching particularly helpful.
Do you know if these techniques and tools would work with the GE Browser plug-in?
THANXS

Oops, please ignore my question – I just re-read your original posts and now understand that manually caching for large areas is tedious, hence the need for the programs!

Hi,

I enjoy reading your blog – I’m an archaeologist and find that a lot of your tips and tricks have a lot of relevance to my own work. I have a simple question about your posts on Google Earth caching: why bother? Is it simply to allow you to have and maintain a local cache of GE data? I can see benefits to this (especially when doing remote work where you don’t have a web connection!) but at the same time if I”m heading bush I just make sure I have had a good browse around all the areas I’m interested in thereby capturing it in the cache?

Or have I missed something? I”m not being critical in any way, I just don’t know and am wondering if there are additional benefits?! Thanks for the great site, I’m glad you started it up again.
