The Challenge
Background
NASA’s open data sources hold an abundance of imagery. Mapping that imagery to a digital globe makes the data interactive and may enable people to discover relationships among ecosystem phenomena. Using a digital globe, such as NASA’s Web WorldWind, this Space Apps challenge involves developing and deploying an interactive web app that enables exploration. A web-app that presents single view of the Earth could present one or more layers of imagery. A web-app multiple views of the Earth can provide side-by-side views of two sets of imagery. A few web-apps have already been developed using NASA’s Web WorldWind. Figure 1 presents a screen shot of NASA World. Figure 2 presents a screenshot of Quake Hunter. Both of these web apps were developed with Web WorldWind.

Skill Level
This Space Apps Challenge requires JavaScript programming skills, an understanding of how to use Application Programming Interfaces (API), and knowledge on how to deploy a web-app. The resources section will provide links to NASA Web WorldWind web app examples and API documentation; also, the resources will provide keywords on how to search for information about web-app hosting. Examples of products from this challenge include: (a) a video presentation that demonstrates a web-app and explains which data sets were used, or (b) a deployed digital globe data visualization web-app.
Keywords for researching web-app hosting include:
- web-app hosting
- code repositories
- how to deploy a javascript web-app
- what is a web service
- geospatial web services
The following links leads to NASA Web WorldWind open source 3D globe library, tutorials, documentation, and examples of web-apps developed with NASA Earth science imagery and data from other federal government agencies.
