Rankin,
You posted a while back inquiring of anyone had a copy of a document explaining OPUS and possibly the results that OPUS gives.
Did you ever track down that document? If so, is it something that you can share easily?
Just wondering...
Thanks,
Jimmy
Jimmy- about the time I posted that, I re-read the OPUS page on the NGS website and realized it was basically the contents of the booklet- maybe distilled down a bit. You'll notice the info in the examples on that page are all from 2004.
Someone from the board emailed me a link the NGS library resource page, which I appreciated, however, I was in the midst of a technology perfect storm, and didn't research the link they provided, by the time the storm was over, I had a new internet provider and email address and that email was lost to the electron gremlins...
BTW - folks at NGS- would you please UPDATE that page to mention that the quality observation indicators listed are not absolute, especially when the observation is used in OPUS Projects....
This may help, it's a slide from a course given by Dave Doyle & Bill Henning at the NJSPLS Conference.

The whole powerpoint can be downloaded at http://www.njspls.org/?page=Handouts2015 It's course number 22.
Thank you for the information
ASCE has a publication which is basically a collection of 22 articles about OPUS and CORS:
It has a lot of good information.
