Custom elevation grids can also be uploaded (Fig.

the scale of the view determines the detail of the elevation grid. NASA World Wind loads elevation data automatically with a multi-resolution approach, i.e. 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.

A DTM is the digital representation of the elevation of a planet’s surface at ground level. The base model is a virtual globe, a 3D representation of a planet, enriched with its digital terrain model (DTM). This visualization technology provides a multi-dimensional geographic information system (GIS) and an extensible framework for analyses and visualization of scientific data.

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 motto is fully realized in NASA World Wind. The National Aeronautics and Space Administration (NASA) was born in 1958 with a motto: “For the Benefit of All”. With this contribution, we want to increase awareness of NASA World Wind as a unique opportunity to foster collaboration between scientists, developers and other stakeholders, enriching knowledge of our Earth’s complexity.

The European Space Agency is now partnering with NASA on development of the 'ESA-NASA Web World Wind' this high degree of interest from other agencies will boost future project productivity. We give here an overview of the project, reporting details regarding current development direction, with state of the art examples. NASA World Wind provides the ideal environment for scientific data, their analysis, visual representation and interaction with users, in a single platform, which can be deployed both as a Java desktop application (NASA World Wind) or a JavaScript web application (ESA-NASA Web World Wind). The primary class for interacting with GeoTiffs in WebWorldWind is the GeoTiffReader class.NASA World Wind is an open source application-programming interface for developing geographic information systems based on a virtual globe rendering engine representing a planet.

In this lesson we’ll demonstrate how to use WebWorldWind’s GeoTiff parsing functionality to retrieve a GeoTiff, parse it, and display the image. WebWorldWind provides a GeoTiff parser which has good support for the most common GeoTiff formats. While one must be aware of the tile matrix support limitations, WMTS configuration and use is very similar to WMS in WebWorldWind. The WmsLayer requires the client to obtain the WMS capabilities document, parse, and create a configuration object.īuild the necessary URL for retrieving the XML capabilities document: WebWorldWind includes the WmsLayer for displaying WMS imagery.

WebWorldWind is capable of interacting with both services. The Open Geospatial Consortium (OGC) has defined the Web Map Service (WMS) and WebMapTileService (WMTS) for delivering map images. This lesson will focus on different mechanisms for displaying imagery within WebWorldWind. WebWorldWind facilitates the presentation of a number of different imagery formats and sources to both enrich the visual appearance of the globe and provide imagery based data. Surface imagery is a vital component to any 3D globe application. NASA WorldWind Workshop Learn how to build web apps with NASA's 3D virtual globe technology.
