NASA World Wind is a graphically rich 3D virtual globe for use on desktop computers running Windows. It combines NASA imagery generated from satellites that have produced Blue Marble, Landsat 7, SRTM, MODIS and more.
The National Aeronautics and Space Administration (NASA) was born in 1958 with a motto: “For the Benefit of All”. This motto is fully realized in NASA World Wind. World Wind is an API-centric SDK, an Application Programming Interface (API) Software Development Kit (SDK) that delivers virtual world for experiencing geospatial data in its native context. This visualization technology provides a multi-dimensional geographic information system (GIS) and an extensible framework for analyses and visualization of scientific data.
The base model is a virtual globe, a 3D representation of a planet, enriched with its digital terrain model (DTM). A DTM is the digital representation of the elevation of a planet’s surface at ground level. It provides information not only regarding elevation, but also allows one to derive other morphological features, such as slope, aspect, with the ability to model these dynamics of a planet’s system processes– e.g. Local solar irradiance. NASA World Wind loads elevation data automatically with a multi-resolution approach, i.e. The scale of the view determines the detail of the elevation grid. Custom elevation grids can also be uploaded (Fig.
) allowing users to implement their own model in NASA World Wind. 1Left: default NASA World Wind elevation grid (SRTM DEM 90 m resolution).
Right: local elevation grid from DTM at 5 m resolution uploaded into NASA World WindNASA World Wind has been available as open source since 2003 in C#, since 2006 in Java, since 2012 in Android, since 2013 in iOS and since 2014 in JavaScript. The purpose of this technology has always been for developers to implement new functionalities and advance existing ones to create increasingly more useful tools for analysis and visualization of Earth and space data ,.The potential to access spatial data is a common and foremost attribute of NASA World Wind.
GIS interoperability is the ability for a platform to read and render multitude spatial data formats , from local sources and from remote public and private datasets via shared open standards. The vision of NASA World Wind is to provide a high-performance open-source 3D planetary model with a large collection of components for projecting images, geometric objects and geographic shapes on the model. Its implementation is modular and extensible, allowing users to develop simple–to-sophisticated applications for their own requirements.An insightful description is given in the homepage of the NASA World Wind organization website , which we report fully: “What is World Wind - World Wind is a free, open source API for a virtual globe. World Wind allows developers to quickly and easily create interactive visualizations of the 3D globe, mapping geographical information. Organizations across the world use World Wind to monitor weather patterns, visualize cities and terrain, track the movement of planes, vehicles and ships, analyse geospatial data, and educate people about the dynamic nature of Earth.

What are its Features and Benefits? It’s open source: NASA World Wind is completely open source, therefore extending the API is simple and easy to do, creating a powerful platform giving any application the means to express, manipulate and analyse spatial data. NASA World Wind technology can be incorporated into Windows, Mac and Linux applications, web pages and web applications, as well as mobile applications alike. Build what you want. NASA World Wind is different from a 3D globe like Google Earth because it is not a completed application targeted at end-users. Instead, it is an SDK (software development kit) that software engineers can use to build their own applications.
SDK contains World Wind API, examples and demos. API provides the virtual globe.
Examples and demos show how to use NASA World Wind code in order to create a wide range of projects, from satellite tracking systems to flight simulators. With World Wind taking care of the hard work of visualizing geographic data (generating terrain from elevation models, selecting and displaying images from imagery servers, etc.), software engineers are free to focus on solving problems specific to their own domains and quickly build whatever geospatial applications they choose.”All the above is available through Java, Android and JavaScript. Reusable code allows to implement functionalities such as a graphical user interface (GUI), a browser designed for the end user, with a fully extensible default layout reflecting a classical GIS application.
Geographic data are retrieved, rendered and can be analysed by interacting with layers and tools designed by the developers.NASA World Wind’s open source essence, with its modular and extensible architecture makes it an ideal platform for education, research and communication on our Earth dynamics. This contribution wants to increase awareness on NASA World Wind as a unique opportunity to foster collaboration between scientists, developers and other stakeholders, enriching knowledge of our Earth’s complexity. The architecture of NASA World Wind provides a high-performance open source virtual globe (of planet Earth, but not limited to it). The virtual globe is a 3D model that can be draped with a large collection of images and geometric 2D and 3D objects. To this end, NASA World Wind is being developed and deployed in Java and in JavaScript, the former for loading the World Wind client locally through a Java Virtual Machine, the latter for loading the application remotely via a web browser (see Table for availability and requirements).
Common to both distributions are the following base objects: Layers, Globe and Tessellator (Figs. The last two providing, respectively, the digital mathematic approximation of the planet’s shape (an ellipsoid) and the terrain elevation grid. 2Overview of the structure of NASA World Wind classes with base objects and their relationships.
Image courtesy of Schubert and Collins Tessellator is the engine for rendering the ellipsoid by approximation, using a mesh of regular shapes, commonly rectangles or triangles. NASA World Wind developers applied a high-performance algorithm, described in Miller and Gaskins. Tessellation is performed every time the terrain’s resolution has to be synchronized with the current viewing state and availability of elevations.Globe is rendered on screen using the tessellated representation of the ellipsoid as an approximation of a planet’s surface and elevation.
The ellipsoid is defined in a Cartesian coordinate system in which the Y axis points to the north pole; the Z axis points to the intersection of the prime meridian and the equator, in the equatorial plane; the X axis completes a right-handed coordinate system, and is 90° east of the Z axis and also in the equatorial plane. There is also the possibility to use a flat representation of a planetary globe, by projecting it to a plane using the default Mercator projection. User-defined projections can be implemented as well.
The default reference system for earth data geolocation is geographic, using latitude and longitude angles in a WGS84 Datum. Height can be provided as meters above sea level. Projected cartographic reference systems (e.g. UTM) and different Datum such as WGS84, NAD27 and many others are supported. Projections are supported through the Proj.4 library. For a reference regarding projections and cartographic reference systems see Evenden and Warmerdam , in global GIS applications see Battersby et al.Layers is the class providing access to spatial data added to NASA World Wind. Most spatial data are stored as raster models, e.g.
Aerial or satellite imagery, temperature grids etc, and as vector models, i.e. 2D or 3D geometric objects. Some examples of spatial data visualized in NASA World Wind are in Fig. Layers are linked to spatial data available from local and remote repositories.
Specific implementations allow interpreting, geolocating and rendering such data on the globe. Most supported formats of spatial data are available thanks to the GDAL library. World Wind - JavaThe structure of the API is represented as a simplified diagram in Fig.
The Globe, Tessellator and Layer classes have been discussed in the previous section, as they are common to the Java and JavaScript APIs. These three classes provide the Model segment that is then rendered in the WorldWindow segment, allowing visualization and interaction between the data, the user and other modules. A developer can extend existing modules easily and add custom tools and plug-ins creating simple to complex applications.Layers can be populated with raster and vector models. Vector representation can be summarized in point, polyline, and polygon objects. For a more in-depth description of vector features please consult the Open Geospatial Consortium (OGC) Simple Features specifications. Points, placemarks and markers are useful to pinpoint locations and they can be enhanced with symbols, icons and labels. Polylines are useful to create paths, show a direction and delimit areas with boundaries.
Figure at first row depicts these two features in NASA World Wind. 3D vector objects are cylinders, spheres, cones, pyramids. 3D polygons can be created by extrusion of 2D polygons. They can be draped with images in order to create realistic complex objects (Fig.
Second row first column). The position of the object in terms of height can be fixed on the ground or set at a user-defined height. The user can interact with vector objects by querying them or also by modifying their geometry and position manually with editing tools.Data are retrieved from the web and cached locally for best performance and organized as layers. Raster and vector models are supported. Supported raster formats are the following (for a description related to each abbreviation see ): JPG, PNG, GeoTIFF, JPEG2000.
Supported vector formats are the following (for a description related to each abbreviation see ): ESRI Shapefile, Keyhole Markup Language (KML), VPF, GML, GeoJSON, GeoRSS, GPX, NMEA.Web Map Service (WMS) and Web Feature Service (WFS) are standards from the OGC used to collect dataset from web services. Figure at second row second column shows an example of MODIS Average Land Surface Temperature accessed by WMS. Through the WMS service, the NASA Server also provides availability to several layers: e.g. Blue Marble Next Generation (BMNG), LandSat7 based imagery, USGS imagery. Elevation data are provided by the server as well, using a combination of sources from ETOPO2, NASA SRTM and USGS NED.Many modules for interaction between the data and the user are available in the NASA World Wind Java API distribution.
In the last row of Fig., on the left, the elevation data and a user-defined location is used to calculate which points are visible in the surrounding environment; on the right, the terrain profile along a user-defined line is extracted. 5From top left in clockwise direction: - vector points represented as labels and icons, - 3D polylines - raster with temperature from open datasets (MODIS) – terrain profile – view/terrain interaction (yellow dots represent a blocked view) – extruded polygons draped with images Web World WindAccessing spatial data and GIS tools through the web has been a popular solution since internet became available for private and public access.
NASA World Wind has recently (2014) been ported to a JavaScript API for developing interfaces which are accessible directly via a web browser, without other requirements. This API is being enriched with functionalities from the Java version. As stated in the project’s webpage (Table ): “NASA Web World Wind is a 3D virtual globe API for HTML5 and JavaScript. Web pages include Web World Wind to provide one or more virtual globes on that page. The European Space Agency (ESA) is also partnering with NASA on development.
NASA Web World Wind runs on all major operating systems, desktop and mobile devices, and web browsers”. 6Structure overview of the NASA Web World Wind applicationThe WorldWindow is an object, which contains all the NASA Web World Wind functionalities and connects them to an HTML container: the canvas. Each application implementing NASA Web World Wind should have at least one canvas in its webpage, with a WorldWindow object, linked through its identifier.The globe is the 3D representation of the Earth, a WGS84 ellipsoid containing tasselleted elevation data, though it is also capable of showing several 2D projections. The implementation of the globe and its tessellation follows what is described previously in the Section “Architecture”. Usually, applications do not interact directly with the globe but implement methods to get information from it, even though it also possible to edit the globe’s features.Layers are fundamental objects to implement several features. Besides the WorldWindow, they are typically the immediate way of interacting with spatial data loaded in a GIS.
NASA Web World Wind can access a multitude of built-in imagery and terrain formats. It can display multi-resolution imagery, terrain and geometric data using multiple supported formats. GeoTIFF, JPEG and PNG formats are supported for raster data, and ESRI Shapefiles, KML and Collada formats for vector models (see reference to project webpage in Table ). REST, WMS and Bing map services are supported as well. Layers allow shapes in 2D, 3D and also user-defined elevation data. Also available in the API as layers are utilities like the compass layer, graticules, coordinates display and view controls. View controls allow users to navigate in 3D using zoom, panning and tilting of the view in different directions.
Upcoming features include HDF, DTED, NITF and FBX vector format support , WCS, WMTS and WFS service support. Also, new utilities are about to be added to the JavaScript API distribution for on-screen measurements, calculation of line-of-sight, creation of analytic surfaces and subsurface visualization support.The Navigator is responsible for converting user actions to manipulations of the globe. It monitors mouse events and user gestures and translates them to pan, zoom or tilt operations on the globe.
The Navigator can also be driven by the application to change the viewpoint to a particular location or to set its tilt and heading. The Navigator is an object automatically integrated into each WorldWindow, allowing interacting with the globe to get all the information about its position. Developers can customize mouse movements and gestures to navigate the globe in different ways. The Navigator can also be controlled by mobile devices and can be personalized to assign any mobile gesture to a particular action in the globe.Among the features there are also geocoders that permit discovery of geographic locations from a query string.
NASA Web World Wind implements the one from Open Street Map’s Nominatim geocoder at MapQuest. Thanks to this geocoder, it is possible to retrieve information about a city, area or location from its name or coordinates and then show all the desired information in the globe.NASA Web World Wind contains several other objects; most of them run behind the scenes, so programmers are not required to interact with them. Instead, when programmers want to extend the NASA Web World Wind features, they only need to interact with specific components, using the JavaScript API. As a result it is quite easy to extend the features already implemented or even create new ones.NASA Web World Wind provides a rich set of features for displaying and interacting with spatial data. It is designed to be extensible; adding functionality is simple and easy to do by extending existing modules or linking new tools as plug-ins. Results and discussion.
Since its release as open source in 2003, NASA World Wind attracts a large number of contributions from the open source community. The powerful modular architecture of NASA World Wind attracted improvements to the core functionalities, implementation of add-ons, delivery of high-resolution data, and outright development of GIS solutions. in their article report information on add-ons and high resolution data available for NASA World Wind at the time of writing their contribution.In this section, we report three solutions developed using NASA World Wind, and three solutions developed using NASA Web World Wind. What is reported is, obviously, a very small subset of many excellent applications developed by software engineers, students and professional teams from a large international community.
We attempt to represent a range of different scopes and fields: multi-dimensional data viewers, collaborative solutions, cultural heritage representations, dissemination of science data and access to historical datasets from open data services. Multi-dimensional data viewer - EST-WAThe Environment Space and Time Web Analyser (EST-WA), is based on the netCDF format and is able to visualize spatial-temporal variable distributions in a multi-dimensional interface (e.g. Sea temperature or soil permeability at different depths, air pollution, temperature, humidity at different heights, etc.). By selecting each individual element (variable, domain, grid and axis), it is possible to access the second level of metadata (attribute) and to have the complete overview of the information stored in the netCDF file. Through this window, after the selection of the variable, users can activate the 2D map pre-viewer. Besides the usual browsing functionalities (pan, zoom-in and zoom-out), the dynamic map allows users to interact with the content of the 4D structure and to spatially and temporally filter the data of interest. After the filtering phase, EST-WA3D is activated (Fig.
PoliCrowd is a 3D/4D collaborative platform based on NASA World Wind Java. After the first version which focused on tourism and cultural heritage , the current version, PoliCrowd 2.0, aims to be completely general-purpose and multi-thematic. It is based on the principle of Volunteered Geographic Information (VGI) to create projects according to participants’ interests, as they can connect to any WMS and OpenDataKit (ODK) server and add information.
The users can also share their projects, by saving them in a catalogue available for all the PoliCrowd users. Multimedia content (audio, photo and video) can be added to the catalogue using Android mobile devices and the data are georeferenced using the positioning technologies of the mobile device. The architecture of the system can be seen in Fig. Web C.A.R.T.E. System is a multi-frame and multi-dimensional platform, which allows users to visualize time-varying features on synchronised 2D and 3D panels.
The application provides access to historical maps of Como city, which are superimposed on the current local orthophoto and the topographic map showing city buildings and local DTM, i.e. The Lombardy Region DTM with pixel size of 20m and 2m (Fig. A main innovation is represented by geographic synchronization of the panels, which allows users to look at the same portion of the Earth both on the 2D and the NASA World Wind based 3D viewers. An earthquake viewer built using NASA Web World Wind. This web app shows time and location of the earthquake, magnitude and depth. Data are from USGS information on historic earthquakes. Users can query over 100 years of seismic data dynamically over the whole globe or on a smaller area by defining geographic boundaries over which to subset the data.
The 3D capabilities allow analyses via depth and magnitude of each earthquake, for greater understanding of seismic events and their spatial correlation (Fig. 15World weather app with winds layer and surface rain rate layer Current status and future developmentsThe NASA World Wind team is currently actively developing three platforms for the NASA World Wind application. The oldest one is the desktop implementation using Java, and was described in this article along with its web implementation using JavaScript. Implementations for Android and Web platforms are undergoing highly active development. Requirements and constraints of the Android and Web demos are available from the NASA World Wind’s main web page.Among the latest features under development, it is worth to mention the implementation of a ‘picking’ functionality to enable users to pick an object available in the chosen screen point. Also the atmosphere effect with a day/night cycle has been developed alongside some unit tests to allow quality assured integration for each feature and in future they could be reused in other projects.Development is also active on the Web version of NASA World Wind, now composed by a team that involves contributors from NASA, ESA and Thales. This group is working on porting many of the Java features to the Web World Wind SDK.
They are also focusing on the performance. To accomplish this, the programmers continually analyze the code base for performance issues, and research improvements including feedback from the user community.At the time of writing this article some interesting features currently under development are about to be released thanks to the concentrated and collaborative effort of programmers. These new features allow importing KML, GeoJSON and Collada spatial formats.
Another important feature which will soon be released is OGC’s WCS service, which is still under active development. In this article we have tried to provide the reader with an overview of the NASA World Wind project, outlining some existing applications and highlighting its potential for collaborative development in a wide range of applications for many aspects of science.Participation and collaboration is a fundamental part of open source projects , , and NASA World Wind thrives through the effort of young developers and the experience and dedication of mentors.In this era, spatial data are growing exponentially in terms of volume and variety, and are often simply referred to as “bigdata”. This brings new opportunities, but also new challenges, in the ways we approach analysis and visualization of spatial data. NASA World Wind provides the platform for accurate and performant visualization of spatial data.
This greatly facilitates the ability for scientists and software engineers to develop important analyses for better understanding of Earth, its environment, dynamics and complexity.NASA World Wind improves every day thanks to a passionate community and is available across all platforms, for the benefit of all.

Nasa Worldwind Suspension
NASA being the big name that it is, we expected its 3D global-imaging program to be made of sterner stuff. Unfortunately, it fell flatter than a collapsed playing-card house.Less cluttered than Google Earth, with a simple toolbar array of clickable icons that enlarge when you mouse over them, World Wind's promising interface belied too many problems. More than half of those toolbar functions did not work, or were taking so long to render that we had to move on to other things-like sleep. No combination of settings could get the real-time weather maps to show up, nor did the Astrobiology Field Guide do anything at all, despite the cool name.The Lewis & Clark Trail feature worked, as did the Landmark toggle, the switch from orthographic to topographic renderings, and the Zoom function, so there is hope. You can also look beyond Earth to other planets in the solar system.
Some of the app's 3D renderings are very highly detailed, but only for a short list of specific places, like Death Valley.At this point, though, we can't recommend bothering with World Wind when there are better functioning, more customizable global-mapping programs out there.
