The Global Geographic Names database contains the names and location of approximately 6.5 million features of interest throughout the world. The features include mountains, government buildings, forests, parks, and many more. Many of the locations in this database are already included in the default Google Earth installation when you enable the Places of Interest layer; however, they are sometimes difficult to see if you do not have the Google Earth view in exactly the correct location and the Places of Interest layer does not contain all of the entries.
This list was created by merging the Geographic Names databases maintained by the USGS and the National Geospatial-Intelligence Agency (both updated as of December, 2009). Only the feature names, classification and locations were extracted from the source databases to keep the file sizes manageable in Google Earth. Even with just the basic information, this is almost 300 megabytes of raw data and 1.5 gigabytes of KML code.
The placemarks were broken down into 2×2 degree tiles sections which will load and unload automatically as you navigate around the earth. Just zoom in close to the earth and the placemarks should become visible automatically. Dense urban areas might take a few seconds to load, depending on the speed of your internet connection. They won’t become visible until you are fairly close to the earth.
