If you let me know which particular area you are working on, I could send 
you my processed data.

I believe that's what happens.  If you are seeing contrary evidence in the 
results, I could take a closer look at the code and see if I can remember 
how it works.

This is most likely a texture problem.  I would venture a guess that the 
line isn't perfectly centered in the texture.

Probably build each building as a separate model and add them to the 
corresponding .stg file.  This is what we've done for KSFO.

That sounds like an interesting project.  I've worked on a similar project 
with snow plows:

    http://www.its.umn.edu/research/ivifieldtest/index.html

If you have any information available about your project I'd love to be 
able to read through it.
