Benefits to developers from Google earth
It is really very interesting to know how Google Earth Works and what is the underlying technology of Google Earth. Despite some intellectual property concerns we are trying to explain Google earth which common man can understand. As it was open source software it was attacked once. Many times it was claimed that the technology is copied but it was completely dismissed. However, it is comparatively very low other open source. How Google earth is developed is disclosed in various forms. As the technology is patented we can talk about it openly. You can read patents directly. Google has patented many related technology which they are trying to enhance.
Google earth source code has been written for several times and tested in adverse situations. The latest implementation has been significantly changed. There are two major differences in Google Maps and Google Earth. With Google maps you can see 2D maps but with Google earth you can see 3D rendering. Google earth provides real time images as oppose to that Google Maps provide pre-rendering graphics. However, both have begun with traditional digital photography. Both provide the high-resolution pictures but the way the render data and images differs largely. If you make settings for one pixel of color for every square kilometer you would see great resolution images with Google earth.
It is far better than any other 3D graphics hardware. It will work with in 800 mega pixels and 204 gigabytes as today’s PCs have at least 2GB memory. Your 128MB PC can render videos. Even 2 kilometer wide resolution you can see rivers, roads and even people would be apparent. US cities can resolve objects as small as half a meter. Images literally take very few terabytes to store. There is no other way that can work as efficiently as Google earth source code, especially providing real-time images. You can rotate your view anywhere in the globe except underground of earth.
The source data needs to be delivered to your monitor. If you have decided to use source code then you have definitely simplified your engineering problem. You can cut Google Earth tiles for your application that will even provide you 3D view. Other part of your application you can develop on your own way. Google earth will solve your problem in truly novel way. Anyone who wishes to develop image based application, he or she must learn few core concepts about computer graphics. This will make your work easy enough.
First we will focus on, how 3D rendering works and texture mapping is done. Textual filtering is also vital part to study. It will also help you to grasp progressive advance techniques. It will give you overall understanding of entire application and you will be amazed just by taking quick look of basic concepts. The most common technique used for rotating, scaling and warping images is Bilinear Filtering. First select few images and then see the pixels are used to blend them together. Hove some patience and you will slowly start developing your own source code.
