The SDSS add-on displays data from the Sloan Digital Sky Survey, in World Wind. There is a Quicktime movie of this add-on available

click here to view it.



Download SDSS add-on v1.2 and double click the downloaded file, follow the on-screen prompts to install the add-on.


To use the add-on load World Wind, and select SDSS from the file menu (see figure 1), or click load SDSS, you will now see several new icons on World Winds toolbar (see figure 2).

The buttons provide access to footprints of different astronomical surveys together with images from these surveys. Currently Footprints are available for the SDSS survey (Data Release 5) and the FIRST radio survey. Images are available for the SDSS (Data Release 4) and the Wilkinson Microwave Anisotropy Probe (WMAP; Year One data release). More surveys will be added over time.

Transparency can be used to view two, or more, of these layers at once by right clicking on the imagery name in Layer Manger, for detailed instruction on using multi layer transparency in World Wind see the Transparency, multi-layer page.

Data source

The Sloan Digital Sky Survey (SDSS) - The Sloan Digital Sky Survey (SDSS) is the most ambitious astronomical survey ever undertaken. When completed, it will provide detailed optical images covering more than a quarter of the sky, and a 3-dimensional map of about a million galaxies and quasars. As the survey progresses, the data are released to the scientific community and the general public in annual increments.
