Overview on World Wind features and add-ons
If you add new features to the program NASA World Wind, then you can easily add add-ions. The amount of functionality, which you are able to add to your NASA World Wind using these add-ons, is enormous. In short, you will be addicted to make use of these add-ons. Sea level standard add-on: This add-on is very well-liked as it includes shaded relief maps that show current sea level as well as sae levels that are 80m higher and 120m lower. These correspond to values of last ice age and outcome of melting of Antarctic and Artic icesheets. Make sure that you should have the latest version of this add-on for accessing its advanced version.
You will glad to know that an add-on has been developed to show variations in gravitational fields expected from a homogeneous, smooth sphere. It is known as gravitational anomaly add-on. Many factors are responsible to get these deviation results. Differences in composition, crustily thickness as well as elevation can lead to alterations in strength of gravitational force for a given location. This add-on has semi-transparent as well as opaque representations of relative strength of gravitational forces across the globe.
One more NASA World Wind add-on that should be installed in your computer is post glacial ice- cover. It is simply amazing. This add-on can depict the global ice sheets completely as they have ultimately retreated since last ice age about 17000-20000 years ago. In this add-on, maps are included every 1000 year intervals, which can depict data of last 20000 years. Do you want to see the geological age and the makeup of North America? Well, you can view the aforementioned information if you have North American Tapestry add-on. Also included are distributions of several rock formation types. The cartographic tapestry displayed is woven accurately from shaded relief image as well as geological map. This digital combination can show users the amazing geologic history of the North America through interrelation different rock types, topography as well as time. Super volcanoes Add-on: If you want to know about volcanoes that existed for several years then you must use this add-on. It shows largest volcanoes, that geologists often claimed their existence.
Magnetic declination add-on: Do you know that our planet Earth has magnetic field? If “yes” then do you have any idea about the impact it has on the living beings? It is a reality that it is responsible for phenomena such as migration of marine animals and birds. The magnetic field acts like a protective covering. It can shield surface of planet Earth from harmful extraterrestrial radiation. If you are curious to know the properties of your Earth's magnetic field then you must install magnetic declination add-on as it portrays the above mentioned information accurately. The add-on offers information on field strength, inclination and declination of magnetic field. Natural Earth add-on: This map can depict shaded land cover in high resolution. The ocean can be easily turned off, if you wish to make use of with other NASA World Wind layers.
