World Wind NASA: a great learning opportunity
NASA collects its huge terabytes data from different sources like satellite orbiting or telescopes peering into deep space. NASA WorldWind uses technology that can readily deliver geospatial data in easily accessible manner and is most compelled one than any other geospatial data. There is a lot of information about how the WorldWind interacts with this huge amount of data. The API used is primarily for interfaces. It gives ability to user to alternatively change the components. However, interfaces are highest level. These interfaces are developed in Swing and AWT component of JAVA technology. There is very vast code to work the application with great performance and speed.
After taking a close look of WorldWind NASA, you will come to know that there are major five WorldWind interfaces. First interface is Globe that represents terrain and planet’s shape. It also includes imagery as well as information about the globe. It is the biggest layer of entire model of WorldWind NASA. This layer typically includes earth, mars and other planets too or you can see entire universe. The second interface called rendering model is responsible for giving updated images, events, timings along with user’s mapping actions. User’s view of the model is controlled by this layer by controlling its involved components.
The objects created to implement these interfaces are created by application developers. Objects created are used wherever that particular interface is used. All the objects are created globally, each representing different planets like moon, mars or earth. It provides basic implementation of all interfaces to view the model. There are number of interfaces like SceneController, FrameController. It controls the integration of entire application with java programming. All data required is drawn from local computer from the cache. The way application handles the images along its appropriate information will give developer great opportunity to explore themselves about how to IT industry works in such complication situations.
Cache file manages disk storage space and unifies access to all files. It is a singleton file accessible through WorldWind NASA. The application is giving more data about different planets, stars, weather, time series and satellites. It will also provide data formats that will support native language. Soon they will launch animation manger, layer manager and drag and drop functionality to help users to interact with the application more easily. Additionally it will support API’s for scripting extensions and RSS feed support. Next version will include NetBeans and Eclipse IDE integration which will display the globe in WorldWind NASA window.
NASA world wind is a great visualization technology and cool software tool. Moreover, it can be added to any application or applet that needs this application. The great imagery provided will give cool look if you use it in your web application. The images are not only provided by NASA but many other reliable sources. This valuable data can be used even by college students as it is a great educational tool. Till date lot of government software and science applications have used the images. It is amazing program with great feature sets.
