Google Earth is a web and computer program that renders a 3D representation of Earth based primarily on satellite imagery.The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles.
Web Mercator, Google Web Mercator, Spherical Mercator, WGS 84 Web Mercator [1] or WGS 84/Pseudo-Mercator is a variant of the Mercator map projection and is the de facto standard for Web mapping applications.
A further convention proposed by FlickrFly adds tags to specify the suggested viewing angle and range when the geotagged location is viewed in Google Earth: ge:head=225.00 ge:tilt=45.00 ge:range=560.00. These three tags would indicate that the camera is pointed heading 225° (south west), has a 45° tilt and is 560 metres from the subject.
Real-time computer graphics or real-time rendering is the sub-field of computer graphics focused on producing and analyzing images in real time. The term can refer to anything from rendering an application's graphical user interface ( GUI ) to real-time image analysis , but is most often used in reference to interactive 3D computer graphics ...
Also, displaying rendered images served from a web server is less computationally demanding than rendering images in the browser, a benefit over technologies such as Web Feature Service (WFS). While many map tiles are in raster format (a bitmap file such as PNG or JPEG ), the number of suppliers of vector tiles is growing.
The original and most common aspect of the Mercator projection for maps of the Earth is the normal aspect, for which the axis of the cylinder is the Earth's axis of rotation which passes through the North and South poles, and the contact circle is the Earth's equator.
Google Developers Live features highly technical, in-depth topics focused on building of web, mobile, and enterprise applications with Google and open web technologies such as Android, HTML5, Chrome, ChromeOS, Google APIs, Google Web Toolkit, App Engine, Cloud, Google Maps, YouTube and more, and give participants an excellent chance to learn ...
The project started as a way for Google to bring full hardware acceleration for WebGL to Windows without relying on OpenGL graphics drivers. Google initially released the program under the BSD license. [13] The current production version (2.1.x) implements OpenGL ES 2.0, 3.0, 3.1 and EGL 1.5, claiming to pass the conformance tests for both.
