The Google Earth Library showcases add-on content for Google Earth. Some of the content you will find here was created by myself, and some of it created by others. To view an item in Google Earth, simply click on the "Download With Google Earth" button, which will be at the end of each post.

A solar eclipse occurs when the Moon passes between the Sun and the Earth, and the Moon fully or partially covers the Sun as viewed from some location on Earth.
This collection of global map overlays for Google Earth shows the paths of solar eclipse predictions through 2100 as compiled by Fred Espenak of NASA’s GSFC. Each eclipse track is identified by the calendar date at the instant of greatest eclipse (Universal Time). The position of greatest eclipse appears an asterisk symbol near the middle section of each path.
Also included is an overlay showing the path of the upcoming July 11, 2010 Total Solar Eclipse that will be visible in the south Pacific Ocean. This map was created by Jay Anderson.

The U.S. General Soil Map consists of general soil association units. It was developed by the National Cooperative Soil Survey and supersedes the State Soil Geographic (STATSGO) dataset published in 1994. It consists of a broad-based inventory of soils and non-soil areas that occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. The dataset was created by generalizing more detailed soil survey maps. Where more detailed soil survey maps were not available, data on geology, topography, vegetation, and climate were assembled, together with Land Remote Sensing Satellite (LANDSAT) images. Soils of like areas were studied, and the probable classification and extent of the soils were determined.
The Google Earth version of this Soil Map provides the locations and names of the soils. Unfortunately, there does not seem to be an easy way to extract detailed soil characteristics for each soil type from the database created by NRCS. If you need the characteristics of the soil, you can search for the name of the soil at this website. If anyone knows of a better way to search for the soil characteristics, post a comment.
This is a very large dataset. The polygon data is several 100 megabytes. To get Google Earth to display the polygons on a national level, they have been split up into 1×1 degree tiles. There is also an Overview map. Simply zoom in and as you get close enough to the ground, the Overview map will automatically turn off and the detailed polygons will automatically turn on. Click on a polygon to see the name of the soil.

On Saturday, February 27 at 6:34:14 UTC, a magnitude 8.8 earthquake occurred near Maule, Chile. News is just starting to come in so not sure how much damage there will be from this earthquake.
I will start working on a collection of map and earthquake data overlays for Google Earth. I will continue to add new maps as I find them in the coming days. If you know of any other good maps or data related to the Chile Earthquake that would be good to add this collection, please post a comment.
Just click on the button below to access all of the maps and data. A list of the data is included in the table below, along with a link to the source.
