1. After installing google earth, users have to connect to its server and depending on the area they wish to view, a request is sent to the server and the corresponding image is displayed.
2. This data is stored in the local cache of the application for subsequent viewing in a proprietary binary format.
3. By loading and replacing the files on the two cds, installed by google earth after first time initialization (authentication by google earth server), one can view imagery and place marks of most of our areas of interest without having to connect to the internet subsequently.
4. For users who have access to internet connection, this data can keep incrementing depending on the level of details they view successively till the cache size reaches 2 gb, after which, the files in the cache will keep getting replaced by the new ones.
The data on the accompanying cds includes “cache” of most of the areas along our borders, specific locations within the neighboring countries, some maps and satellite imagery downloaded and google earth place marks recently updated on 24 mar 06. User who wants higher resolution data for own cities, they can connect to the google earth server on the internet.
