    This is truly astoundingly amazing! When you consider what is actually going on here (with the 3d mappings of 11 panoramic images onto relief data to create one big image)! Very impressed. Now we need to make one in Stereo-3D

    Paul, there are certainly flaws and abberations, but we did our best to create a faithful, natural image. The DEM we used was a wonderful 1M dataset provided by the park, done from a custom aerial scan. One limitation of DEM data is that they don't provide vertical relief data, so we equipped a hang glider w/ multpile cameras, and derived cliff face geometry from Photosynth, see photosynth.net/view.aspx?cid=1a012 e5b-f88f-481f-ab3e-98f32c36665e Will open in
a new tab or window to view the result. As for other uses, yes we have loaded the image and DEM into a Crytek engine, which was quite amazing. We are looking into climbing applications currently.. Thx!

    Very cool! The results are surprisingly seamless and lacking in flaws (though I see some foldover on rock faces, and some leaning trees here and there). I was expecting silhouettes of the cliffs to look worse. Was your digital elevation model the traditional 2.5-dimensional type, elevation as a function of latitude & longitude in a uniform grid, or was it fully three dimensional, modeling overhangs too, for example on El Capitan? Can you give us some rough statistics on the pixel size and elevation sample spacing (in meters)? Do you have any plans for other uses of this 3D model - perhaps virtual hangglider tours, virtual rock climbing?
