If that property is an array of strings, ImageSources or a combination of those, then the first entry in the array specifies the polygon's image source and subsequent entries specify the image sources of the polygon's extruded boundaries. If that property is a single string or ImageSource, then it identifies the image source for the polygon's texture. The textures are specified via the imageSource property of the polygon's attributes. ![]() A curtain is formed around its boundaries and extends from the polygon's edges to the ground.Ī polygon can be textured, including its extruded boundaries. If those attributes identify an image, that image is applied to the polygon.Ī polygon displays as a vertical prism if its extrude property is true. They use the interior and outline attributes of ShapeAttributes. Polygons have separate attributes for normal display and highlighted display. (If the polygon should be draped onto theterrain, you might want to use SurfacePolygon instead.) If the latter, the polygon positions' altitudes are ignored. See also SurfacePolygon.Īltitudes within the polygon's positions are interpreted according to the polygon's altitude mode, which can be one of the following: It may havemultiple boundaries defining empty portions. The polygon may be extruded to the ground to form a prism. ![]() Features include, 3D virtual globe, 2D map with multiple projection choices (Mercator, Polar, UPS, Equirectangular), imagery and elevation import, extensible, data retrieval (via REST, WMS, WCS, WFS, Bing, User-Defined), decluttering, measurement, accurate line-ofsight, subsurface visualization, and more.Represents a 3D polygon. Web WorldWind runs on any platform via a browser, i.e., Internet Explorer, Firefox, Chrome and Safari. WebWorldWind also provides platform independence, while accommodating any number of data types. It is written in JavaScript and provides the real world geographic context for spatial data and information visualization, using a rich set of shapes and graphic primitives. WebWorldWind is an application component, not an app in itself. Apps built with this web version are ideal for immediate social media type activity and also facilitate delivery of sophisticated data exchange scenarios such as weather and climate research, disaster response, personal navigation, and industrial-strength tracking for transportation, supply chain, aviation and satellites. The web version of NASA WorldWind (WebWorldWind) has made it possible for a whole new suite of applications for managing and sharing spatial data. This allows you to provide maximum value of the information to your user community. You decide how the data is accessed and experienced. Unlike other virtual globes such as Google Earth, NASA World Wind offers something very special, full control to customize the interface with any features or functionalities you might need. For developers, by simply updating the app on your server, the latest version of your application is now immediately available to your entire usercommunity. Without the need to install an application, spatial data can now be experienced via any web browser, mobile devices included. ![]() Recently, the accessibility of spatial data has dramatically improved. This presentation will demonstrate several NASA open source use cases for WorldWind technology that include advances being made to optimize access to NetCDF and HDF data via WebWorldWind.NASA WorldWind: Multidimensional Geospatial Web Platform The ability to see spatial data in its native context is essential for that data to be appreciated whether by the scientific community, policy and decision-makers or the general public. Federal Aviation Administration, FAA, uses WorldWind, as do applications currently being developed by the European Space Agency, along with several other US and European government agencies and industry partners. The next-generation National Airspace System (NAS) aviation management system for the U.S. This enable it to be continually optimized and feature-enriched in ways that allow applications based on this SDK (Software Development Kit) to benefit Earth Observation, especially Open Science, with minimal or no adjustment for the decade ahead. ![]() NASA WorldWind: Open Source Visualization Technology for Earth Observation NASA WorldWind: Open Source Visualization Technology for Earth Observation WorldWind, open source virtual globe technology for Java, iOS, Android and Web, is provided by NASA and is architected as API-centric modular componentry.
