A collection of four overlays showing the following data related to the Ionosphere:
- Radio Activity
- Total Electron Content
- Maximum Usable Frequency
The data free data is delayed by three hours Real-time data is available through a paid subscription.
Placemark collection showing the distribution of AIDS cases in 149 countries. The size of each placemark correlates with the percentage of AIDS cases in the population of the country.
The source data was obtained from the United Nations Program on HIV/AIDS.
Excellent use of Google Earth to help tell the story of elephant poachers in the Zakouma National Park, in Africa. The KML file contains links to photographs, habitat boundaries, and other information pertinent to the story.
The full story is available online from National Geographic.
Collection of placemarks showing the locations and summaries of 1,000′s of grants awarded over the years by the National Geographic Society. Some of these studies date back more than 50 years.
The Internet Radio Linking Project links radio systems across the Internet. I would suggest checking out the IRLP website for further information.
The file below will display the IRLP nodes in Google Earth along with their current status and other general information. There are a couple different websites that provide this data and both sets of data can be accessed via the KML file below.
Real-time tracking of over 700 satellites orbiting the Earth. The satellites are grouped together in numerous categories and their positions are shown in Google Earth relative to the Earth’s surface. Their positions appear to update every minute or so.
When you first enable this layer in Google Earth, it will try to load all of the different satellite categories. I would recommend that you disable all of them, then turn on one or two at a time.
The Open Street Map project is a collaborative effort to map the entire globe. A global atlas created by users. This file will overlay the Open Street Map project onto Google Earth.
The detail of the maps increases as you zoom in to show the names and locations of neighborhood streets.
FEMA has two applications to display various flood related data in Google Earth.
Stay Dry - This is the simpler of the two applications. When you start Stay Dry, you’ll see an overview map of the US that shows which areas of the country have coverage available. If the area you are interested in is shaded in purple, then there should be flood data available in Google Earth. As you zoom in, the layers will change to display the flood zone data.
FEMA NFHL - This application displays a large amount of data and may be a little difficult to figure out without spending some time reading the instructions.
These are both very useful tools. The FEMA website has a lot more information, including detailed instructions for both applications. I would highly recommend reading the instructions before using these applications for any kid of official use.
