Download, save, and unzip these three sample data files. You can then open and work with them in the Web World Wind application:
I want to especially acknowledge the support I have received from the NASA World Wind development group – in particular, Tom Gaskins and Dave Collins – as well as the enthusiastic participation of a critical group of users from the City of Springfield, Oregon, most notably Brandt Melick and Chris Zeitner. The use of data they have provided as well as their ongoing encouragement and feedback have been central to the success of this effort.
The full Java version runs on all current platforms (Mac, Windows, Linux).
The Web World Wind version has been extensively tested using Firefox and Google Chrome browsers on both Macintosh and Linux machines. The current Windows implementation of WebGL/GLSL apparently has a problem that prevents the GLSL program from linking.
