Google Earth displays a layer where models of buildings and constructions that can be seen in its three-dimensional form. Initially, existing in Google Earth 3D models were usually created by users around the world with the Google SketchUp or Google Building Maker tool. Currently, anyone can add models to Google Earth. These virtual buildings are then exported the native extension of Google Earth kmz, and are subject to approval by Google. Once approved are published through the buildings in 3D.
However, during 2013 began to come into cities automatically played with help of LIDAR technology, based on aerial shots. This mode gets rebuild complete physiognomy of the city in a more homogeneous manner and rendered in not-too-close view. Effective October 1, 2013 Google prescindirá models which users, to incorporate its LIDAR technology to all regions of the world.
Features:
Google Earth allows you to enter the name of a hotel, school or street and get the exact address, a plane, or view of the place. Satellite images of the planet can also be displayed. Also offers 3D features like giving volume to valleys and mountains, and in some cities have even modeled the buildings. The move on the screen is easy and intuitive, with simple and manageable dashboards.
In addition, it is possible to share with others users links, measure geographic distances, see the height of the mountains, see faults or volcanoes and change the view both horizontally and vertically.
Google Earth also has connection with GPS (Global Positioning System), data from file and database feed their paid versions.
It also has a Flight Simulator in Google Earth quite real that can fly over anywhere on the planet.
Version 4 has added significant improvements:
Interface in English, Spanish, French and German.
Relationship with SketchUp, a program of 3D modeling 3D models of buildings from which can be uploaded to Google Earth.
Control Panel that interferes more discreet and wins in space for the display of images.
Improvements that allow you to view "textured" 3D images (more realistic surfaces, windows, bricks...)
Version in the three major operating systems for personal computers (Windows, Linux, and MAC).
