Wonderful tools of Earth 3D
In recent years, common people are browsing planet earth as a 3-D globe. Here are given five major three dimensional map applications that allow any user to play with earth in 3-D globe.
Google earth: Google introduced keyhole, which is a desktop 3-D mapping application and makes it available free for people. You can easily download this desktop free of cost. This desktop is a fun play ground along with KML, open markup language, allows users to add your data layers. 3-D authoring tool and Google Sketch up of Google lets users to add 3-Dimensional objects on it.
Arc Explorer: Arc Explorer is the largest GIS Company from ESRI. ESRI offers Adobe Flex based ArcWeb Service explorer that is used by Yahoo Map. This company totally focuses on Geo data and even Geo processing. Many people don’t know the fact that bigger part of world’s geo computing is using ESRI products.
Microsoft Virtual Earth: Microsoft is a software company that is serious about its products, and it is going to integrate virtual earth into enterprise space. They have announced that coming version of SQL server sill be surely made with spatial data management capability.
NASA World Wind: This program is an open source 3-D globe viewer along with API. You can easily download .Net version as well as new Java version here.
Terra explorer: Terra explorer is from skyline that is small but belligerent three dimensional visualization company. It is a fun to play for the necessary browsing feature. You like flying airplane as vision point kind of approach. It is very tough to explain the 3-D effect things. For that you should go play it. However, first you need to download it from here.
If we observe, visualization technologies are getting mature and commoditized. We will see several geoweb companies will pop up. Earth 3D is a program that can run on operating systems such as windows, Mac OS X and Linux. It is very tricky to support all three platforms and especially it is difficult to include required Q T libraries in Mac OS X package. But, the java version is very quick for real OpenGL based 3-D graphics. You are able to retrieve Java code version through Subversion repository of source version.
To get startable configuration of program Earth 3D, you need to follow few steps that are given here.
First, you need to check the sources through Sourceforge. After this, you must visit https://jogl.dev.java.net/ to obtain JOGL for your own platform. Now accumulate it by making use of “src” as source directory as well as “lib” as library directory by making using your desired IDE.
At last, you need to start the class org.earth3d.jearth.main.Earth3dMain. This application can be used to view our beautiful planet earth. There are several people, who like to incorporate 3-D earth into their program. One new subproject known as Earth3d Lib is created that offers us a QT Widget displays the planet earth and allows to include our own content easily.
