Explore different points of interest using Google Earth
Google Earth is a global program application that was firstly known as “The Earth Viewer”. It maps out the planet earth by superimposing the imagery that is taken from the aerial photography, satellite imagery and the GIS 3-Dimensional globe. The Google Earth program prevail under three licenses that includes Google Earth plus ($20 per year), Google Earth that is a free version that has limited functions and Google Earth Pro ($400 per year) is intended specifically for commercial use.
Google Earth can show users the images of the satellite that are of different resolutions of the earth’s surface. This Google Earth feature enables the users to view different things such as cars or houses, etc from the bird’s eye view. This degree of resolution depends on the points if interest, to some extent. However, most of the land areas are covered in 15 meters of resolution. Cambridge, Vegas, Nevada and Australia are few examples of highest resolution at about 15 cm or 6 inches. It is possible for the users in the program Google Earth to search for the addresses of some countries, enter its coordinates or just make use of the mouse form browsing a particular location.
This product was renamed as Google Earth in the year 2006. It can be used on your computer that runs on Microsoft XP, Windows 2000, and Mac OS X 10.3.9 or above, Vista, FreeBSD, and Linux. It is also available as a browser plug-in forIE6, IE7 or Firefox. It has an additional feature, which can adds up the imagery form the database of the Earth to their mapping software’s, that are based on the web. The release of the program Google Earth has driven the interest of the public in geospatial applications and technologies.
Google Earth has the ability to show users the three dimensional structures and buildings like bridges, etc that comprises of the users submissions. This is done by using the Google Sketch up, that is also a three-dimensional modeling program. Initially it was developed for helping the Local and State Government to carry out their functioning in the town planning process. It included the high-resolution photo realistic consistency that you will not find anywhere on the planet Earth. Some structures as well as buildings around the world have a three dimensional rendering through the Google’s 3D Warehouse and related websites. You can also check the traffic speeds at loops situated at every 200 yards through Google Earth.
DEM (Digital Elevation Model) data is used by the program Google Earth. This data is collected by the NASA’s Shuttle Radar Topography Mission. This simply means that now users are able to see the Mount Everest or the Grand Canyon in a three-dimensional form rather than a two-dimensional form alike the other map sites. People using this application have been adding their own data and making it available by using different sources like the blogs or BBS. You can view all kinds of images laid on the Earth’s surface by using the Google Earth. The management of the three dimensional geospatial data is supported by Google Earth through the Keyhole Markup Language.
