Let's see if we can get anything else out of my DEM around Cape York.

I follow the standard USGS way of making these DEMs, so I'm happy with the method, it's just that the results can vary from place to place. I haven't made one around Victoria because, well, it had already been done, and Santa Maria was just off this stereo pair. But Doug and I had some success with a DEM of the pathfinder landing site (http://www.youtube.com/watch?v=uE_Ih0hgnlw), and I'm churning these out for my science at the moment and they match up well with MOLA, CTX, HRSC data. I guess Cape York is actually a nice test!

Profiles are no problem, but they're all pretty similar - the local slope into Endeavour just drowns most of the Cape York signal. That could be correct, or it could just be affecting the way that the DEM came out.

Here's a 3D perspective of Cape York, with a crazy x7 vertical exaggeration.

Looks pretty, but I wouldn't bet the house on it!
