Microsoft SeaDragon Maps

I stumbled across a new (to me anyways) website from Microsoft Live Labs called SeaDragon which will process huge image files and make them available in such a way that they can easily be viewed online.

So far I have been able to get it to process a map as large as 1.4 gigapixels.  SeaDragon even hosts the image tiles for free. Kudos to Microsoft Live Labs on this one, I’m impressed. Unfortunately there is no way to view the maps in Google Earth or Google Maps.

Below is a 1.4 gigapixel terrain map of the United States in Albers Projection that I created using a texture map from NASA with hill shading added from SRTM and GTOPO elevation data.

Don’t forget to click on the little icon in the bottom right corner to view it in full-screen mode.




A few others are linked below and I will add some more as I have time.

Source of data:

Scripps Institution of Oceanography
NASA’s Blue Marble imagery
GTOPO
