Overview

World Wind was released for the first time in 2004 by NASA. The latest version (1.4) developed mainly by open source community members from World Wind Central/Free Earth Foundation had its premiere on February 14, 2007. World Wind Central is a community portal for users and developers of NASAs open source World Wind satellite imaging software. ...

Apart from the Earth there are several worlds in World Wind: Moon, Mars, Venus, Jupiter (with the four Galilean moons of Io, Ganymede, Europa and Callisto) and SDSS (imagery of stars and galactics). All these worlds are available in the File menu. This article is about Earths moon. ... Adjectives: Martian Atmosphere Surface pressure: 0. ...

Users interact with the selected planet by rotating it, tilting the view, and zooming in and out. Five million placenames, political boundaries, latitude/longitude lines, and other location criteria can be displayed. World Wind provides the ability to browse maps and geospatial data on the internet using the OGC's WMS servers (version 1.4 also uses WFS for downloading placenames), import ESRI shapefiles and kml/kmz files. This is an example of how World Wind allows anyone to deliver their data. Geomatics is the discipline of gathering, storing, processing, and delivering of geographic information. ...

MSN Virtual Earth is a free online virtual globe map service by Microsoft. ... A non-commercial enterprise is work that values other considerations above and beyond that of making a profit. ...

World Wind uses digital elevation model (DEM) data collected by NASA's Shuttle Radar Topography Mission. This means one can view topographic features such as the Grand Canyon or Mount Everest in three dimensions. In addition, WW has bathymetry data which allows users to see ocean features, such as trenches and ridges, in 3D. 3D rendering of a DEM of Tithonium Chasma on Mars A digital elevation model (DEM) is a digital representation of ground surface topography or terrain. ...

Oceanic Ridge Oceanic crust is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at trenches. ...

Many people using the applications are adding their own data and making them available through various sources, such as the World Wind Central or blogs mentioned in the link section below.

All images and movies created with World Wind using Blue Marble, Landsat, or USGS public domain data can be freely modified, re-distributed, and used on web sites, even for commercial purposes. The public domain comprises the body of all creative works and other knowledge—writing, artwork, music, science, inventions, and others—in which no person or organization has any proprietary interest. ...

World Wind Java

Despite being open source, World Wind is still restricted to Windows, relying on the .NET libraries and DirectX. Future version of World Wind will be developed in Java with JOGL. The new version will have an API-centric architecture with functionalities 'off-loaded' to modular components, leaving the API at the core. The intent is to allow plugins to be used as interchangeably as possible (i.e. via Python). This refactoring exercise will also allow World Wind to be accessed via a browser. A preview of the World Wind Java SDK^[8] was released on May 11, 2007 during Sun Microsystem's annual JavaOne conference. Microsoft . ...
