A 2-button mouse is sufficient to control the software.
This open source project allows zooming from satellite altitude to any location on Earth. It makes use of several data sources to provide historical as well as current information on storms, floods, fires and other important events. You will get to know about major landmarks with links that will provide additional information. The program may appear similar to some other softwares but it covers a wider range of sources. It is user friendly and very easy to operate.
The software can also give county names of various towns. It also draws boundaries, pinpoint cemeteries and also has world flags. If you wish to use the software, you need a pc that has a fast processor along with 3D video card. Minimum hardware requirements include 256 MB of RAM and 1 GB of disk space.
NASA World Wind is indeed a complete program developed by NASA that will allow you to sail in this world in 3D. Program is developed for every user, even those who are working in science. World Wind uses a number of satellites to give a definite possible picture.
This software application will allow you to literally travel to any place, around the world and you don't have to move an inch from your armchair. You can zoom to the image so closer that you are able to distinguish any region or city that you want to visit.
