Kanchenjunga Photo Comparisons.

These pictures are all rollovers which show the CG composite, and with the mouse over you get the original photo. The renderings were done with World Construction Set 6. The terrain is derived from 90 meter DEM's which have been overlaid with Landsat photos. These photos have an on the ground resolution of about 14 meters so foregrounds have been broken up a bit with WCS bumpmaps. The only way I could get these bumps to show through the overlay was to make a bumpy ecosystem and use the "tint foliage" option on the colour map. This is set to fade out with distance from the camera. Matching the camera positions and focal length of the lense with the rendering points is only approximate.

90 meter Dem's are notorious for having large holes in mountainous areas, which is a blow as these are the areas I am interested in. The holes can be patched with 900m DEM's but this results in a very inaccurate smoothing out of the terrain as you can see on the K2 stuff. (I will be updating this later) . The solution to this is to use Jonathan de Ferranti's DEM's. He has painstakingly patched the holes in all the worlds areas over 7000m and they look just like the real thing as you can see from the pictures below. The Everest region was so bad that I had not considered rendering it. Visit his site for a full account of his work and to download the data at www.viewfinderpanoramas.org

ghunsa 

We were camped in the village of Ghunsa and on our rest day we climbed up to this spot. The landsat overlay does not have the snow but the creek flowing down the gulley opposite can be seen clearly even the kink in it.

Camera position here is very uncertain.

 janu

After our visit to Pang Pema we returned to Ghunsa then headed over the Mirgin La. From the top of the first pass was this view of the southern aspect of Janu (7710m) also known as Kumbahakarna. Note the distinctive "pointy" summit that shows clearly on Jonathan de Ferranti's DEM.

 twins

This is another one of the Twins taken from the same spot as above. The shoulder of Kangchenjunga can be seen on the far right and Nepal peak is off to the left.

 kang dist

To the right is a distant view of Kangchenjunga taken from the top of a large ridge called the Milke Danda, just over 3000m. It had been cloudy and just around sunset we got this glimpse of where we were going. The ridges you can see in the CG had disappeared in the murk and Kabru, on the right of Kangchenjunga , was hardly visible.

 nepal

This is a picture of Nepal Peak (7168m) at the head of the Kangchenjunga Glacier near Pang Pema, the northern base camp for Kangchenjunga. This was the main objective of the trek at about 5300m.

Kangchenjunga is off the picture to the right. The landsat picture has rather dark shadows which obscures some of the detail on all the north facing slopes.

 pema

Here is a group photo of us trekkers. Kangchenjunga is directly behind us. The rounded peak on the right is Yalung Kang (8505m). Kangchenjunga is the more triangular peak to its left (8586m). On the extreme left are the Twins. I lightened the shadows a bit with levels in Photoshop.

 kabru

Descending from the pass toward Tseram on the Simbua Khola were these two views of Kabru (left 7353m)and Rathong Peak ( the pointy one on the right 6678m). The camera positions for both these are dubious. I included the one to the right as it shows the river issuing from the Yalung Glacier.
