Google Earth also allows you to save geographically indexed data layers, such as markers for guard stations in a given area, as KMZ files. You can access all of the data in these files, indexed on the tiles you have saved in your cache, by opening the KMZ file in Google Earth offline.
Google Earth for desktops allows you to change the amount of memory devoted to the Google Earth cache, with a maximum value of 2 gigabytes.
