Thanks, Filip,

My problem is, they all have the same world coords, centered on 0,0,0 for
each one. I'm thinking I can use Geometry.ComputeBoundingBox() to get the
length, width, and height of the meshes, and do a Tranform to place them
relative to one another. I have had a hard time finding much info on this
method, but as the meshes are basically box-like, it should work, correct?
I'm also thinking that I can use these dimensions to translate from
Lat/Long/Altitude to X/Y/Z, as I know the dimensions in meters of the DEM
files. Thoughts?
