Google Earth

Google Earth is a virtual globe program that was originally called Earth Viewer, and was created by Keyhole, Inc, a company acquired by Google in 2004. It maps the earth by the superimposition of images obtained from satellite imagery, aerial photography and GIS 3D globe. It is available under three different licenses: Google Earth, a free version with limited functionality; Google Earth Plus ($20 per year), which includes additional features; and Google Earth Pro ($400 per year), which is intended for commercial use.

Some other are saying if what features do we get from Google earth. Well, Google Earth view satellite imagery, maps, terrain, 3D buildings and even explores galaxies in the Sky. You can explore rich geographical content, save your toured places and share with others.

Google Earth has 2 kinds. Which is the Google Earth Plus and Google earth Pro. Google earth plus that you can import data from your GPS (Global Positioning System) handheld device such as tracks and waypoints while Google Earth Pro is significantly more expensive and offers such features as the fastest Google Earth performance, the ability to annotate maps with lines and polygons, and the ability to export high quality images. The disadvantage of using the Google earth is that many terrorists are now using this king of technology for them to pinpoint their attacks. It shows the satellite photographs show in detail the buildings inside the bases and vulnerable areas such as tented accommodation, lavatory blocks and where lightly armored Land Rovers are parked.

There is this case studies coming from the organization of Appalachian Voices. Which they have a project of Appalachian Mountaintop Removal for them to aim the goal of Show the impact of mountaintop removal coal mining. The site puts a human face on the issue by highlighting the stories of families living in the shadows of these mines. And the Google Earth has transformed how we think about the issue, because it not only allows millions of people around the world to see and explore the impact on our region, but it also allows people right here in Appalachia to see for themselves what is going on in the mountains above their homes and communities.
