Photo Comparisons of Torres del PaineBack to Paine CG |

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 (WCS). The terrain is derived from 90 meter DEM's. The textures were generated within WCS as opposed to my previous efforts which were overlaid with Landsat photos. 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. Visit his site for a full account of his work and to download the data at www.viewfinderpanoramas.org Some of these pictures have the camera position was taken from a GPS I took along on the trek. It made camera positioning in WCS more accurate. I used the data from the camera (digital) for the field of view. The only thing I was not able to record was the orientation of the camera so I just had to swing it around in WCS until it matched the photo. Cloud was a problem on this trip, and so was the fact that there was not much time to fiddle around with cameras and GPS so some of the pictures are not accurately georeferenced. I have noted below which ones may not be so accurate. Surprisingly even the better ones do not look too good. I don't know why. |

This is Admiral Nieto from the main Torres Camp. The central tower can just be seen poking over the shoulder. FOV here was estimated.
Latitude: S50.967995° Heading 272 deg |
| A closer look at the towers from a similar position. note the positioning here is a bit less accurate than that above.
Latitude: S50.967995° Heading 285 deg |

This was taken/rendered from the towers lookout up the Ascension Valley. FoV was estimated. The base of the towers seems well positioned but the Towers themselves demonstrate the limitations of 90m sampling.
Latitude: S50.943962° Heading: 253 deg |
| This is to the north of the range looking at The Twins. This is one of the few accurately positioned shots and it shows.
Latitude: S50.85288° Heading: 236 deg |

Another one of the less accurate shots. this is to the North of the Towers looking at the central Tower poking over the ridge.
Latitude: S50.87269° Heading: 162 deg |
| This was taken from above Camp Dixon looking North. Another accurate one but it does not show much except what we missed in the cloud. Lago Dixon and the Dixon Glacier can be seen.
Latitude: S50.90249° Heading: 334 deg |

Taken at Camp Dixon looking at a peak known as "The Cube". it can also be seen in the rendering above, but that day it was in the cloud. In the foreground is Lago Dixon. This is another accurately located camera.
Latitude: S50.877834° Heading: 336 deg |
| This is another accurate shot . It shows the "Horns" from the camp at Lago Pehoe.
Latitude: S51.07228° Heading: 35 deg |
