Earth, virtual travel in the World and the time
Google Earth is an online service accessible through a software to install on a computer, offering a 3D virtual representation of the world.
Customers are invited to contribute to the project by providing 3D models of buildings, which can be done with Google Sketch Up or Building Maker.
By combining these models with StreetView images, it is possible to virtually visit cities.
A 3D vision is offered of oceanographic funds, to explore up to 11 000 meters trench (the deepest, the Mariana Trench).
You can track the movement of marine life but Google wants to avoid providing to provide information that can be used by fishermen (eg whale killers).
Google has partnered with several sites related to Sea to provide more information to Internet users.
Video: Explore the oceans.
From the version 5, the historical function makes it possible to track trends over time of a geographical location: the construction of a building, a melting glacier, the advance of desertification in Africa ...
Ancient Rome in Virtual Reality
Google Earth not only gives you more to travel in 3 dimensions, but adds the time travel too. In fact you can now visit ancient Rome in 3D thanks to Earth.
To access the fourth dimension, type "Ancient Rome in 3D" in the Gallery folder. But first download the latest version of Google Earth ...
After the discovery of a forest of another age in Africa, Earth has done an archaeological discovery: a very rare hominid in South Africa.
Indeed, from images taken by satellites and reproduced on Earth, researchers are able to identify suitable sites for archaeological research and then focus their efforts on these sites.
Google has integrated the ability to virtually walk into the Disneyland Paris, thanks to Google Earth.
And for a glimpse of the promenade, a video demonstration was put online on Youtube.
To achieve this result, it was necessary to integrate to Earth 85 000 pictures from which have been made textures for a 3D vision.
Liquid Galaxy, the world in virtual reality
To immerse yourself in a virtual world, Google has developed Liquid Galaxy (picture right), a set of screens to view the world through Earth.
The video is awesome ...
The system was installed in many locations across the world, and if you feel able, you can build your own installation!
After the flight simulator, a driving simulator is now available in Earth, of course to be used as a tourist and not for racing. Watching the scenery while your vehicle is moving in the streets of a city that you would like to visit, or across a country, in mountains...
For the simulator to work, you need, if not already done, download the Earth API. When you go on the demonstration page, if the API is not found on the computer, the site ask to download it, then you have just to click on the downloaded executable file.
To use the simulator, choose a starting point and a point of arrival, two nearby towns, for example. The system loads data and you can click on "start" to begin the ride ...
The software operates as a site to calculate routes to which Earth adds the ability to see the scene that we will see!
The accelerator is in the form of a + button to click with the mouse.
The car is not a Porsche or a Ferrari but these are the landscapes that are interesting ...
Games on Earth and uses of the API
Google Earth Ship Simulator is an online game based on Earth. In fact, Google provides an API that allows software to interface with the online virtual representation of the real world it offers.
It lacks just a collision detector.
A Dutch company had the dubious idea of using Street View API to create a Doom-like game: the goal is to shoot at passers of all cities of the world. The application has been very successful with thousands of visitors per minute before being disabled by Google. Apart from the immorality of the thing, it blew the servers. It only lasted four days.
Under the name of "Your Town Model Competition", Google offers its model city using Google SketchUp and Building Maker.
GeoEye is a satellite, funded half by the NGA (National Geospatial-Intelligence Agency) and by Google and other sponsors (all for $ 500 million), which offers the finest resolution ever achieved for aerial images. It provides images of Earth in its service.
While the NGA is an agency serving U.S. security, it is not a spy satellite, on the contrary, the pictures he takes are for the public through the Internet.
The definition allows a precision in detail of 43 cm. Note that U.S. laws prohibit the publication of images with an accuracy of over 50 cm, so it is the latter which is the level of detail in the photo at right. This is the first image taken by GeoEye-1 is a photo of Kutztown University in Pennsylvania.
