To kick this thread off, I've found more good stuff to aid our goal of producing an accurate 3D physical model of the landing site:
The LTVT program can display LRO DEMfiles *and* accurately plot images taken by LRO if the image filesare downloaded and converted to JPEG format first.
What I still need is to somehow put the closeup image files together in a mosaic, and then incorporate the topographic data.
The exact area I'd like to model is centered at 89.66N, 34.75W. This is the highest point in the immediate area, and it appears to be a good place to land.
I'll contact them this week to see how much it would cost for a model.
In the meantime, I think EDRAS's software or Global Mapperwill be able to supply 3D images from the LRO LOLA data.
