NASA World Wind- wonderful 3-D visualization tool
NASA World Wind is named as an open source windows program that lets its users to zoom into any place of our beautiful planet. Leveraging satellite images and Shuttle Radar Topography Mission data, this program application lets its users to experience earth terrain in rich 3-D just like you are present on that location. This program application is developed by NASA, a open source virtual globe. This program can overlay USGS as well as NASA aerial images, satellite images, topographic maps and publicly existed GIS data on 3-D maps of our earth.
Now let us discuss newly released World Wind plug-in known as WmsInterface. This World Wind plug-in also allows its users to connect with OGC compatible WMS servers and view the imagery in 3-D environment of NASA. You can easily handle this plug-in to have control on its interface that leads people through activities such as inspection, display maps and servers. Currently, WmsInterface gives users access almost two hundred servers with 100 different maps.
WMSInterface plug-in allows users to unite different maps to get visual data. For example, the combination of grey map result and low resolution map in high resolution colored map. You are also able to make use of real time maps together with high detailed satellite maps. If you wish to obtain more information about this World Wind plug-in, you must visit World Wind central forum thread. WMSInterface is developed making use of #Develop from icSharpnet and written in VB.NET. This program offers users 3-D visuals of tries and land to show valleys as well as mountains.
By making use of World Wind program, users constantly zoom into past Blue Marble and reveal the tremendously comprehensive seamless variety of LandSat7 data. LandSat 7 is a collection of images from the year 1999 to 2003 in a wonderful 15 m per pixel resolution. It includes color bands such as infrared spectrum. Users are also able to browse a number of sets as they are available in this program. Any updates and changes are inherited by this program application automatically. The high resolution of LandSat makes it possible for people to see their neighborhood, city and landmarks. The LandSat 7 collection is very vast so it can not fit on single machine and hence this program can download only what you see and store a compacted copy on your computer to view it later.
MODIS feature of this program provides you a collection of crucial data that is updated everyday. MODIS catalogs storms, fires, floods, dust and volcanic activity. World Wind program can produce customized view of the data and then marks them on our globe. When users will click any one of the markets that is color-coded, it will immediately download the complete image and displays it. MODIS images have the capability of downloading the publication quality material. A new and fresh collection of imagery is downloaded everyday. This software program can browse through and display Globe data whenever user wants it. You can even view cloud cover, barometric and rainfall using this program.
