It seems reasonable to think that removing the huge pecan tree east of the ProFlex500 base station antenna would influence the OPUS results. But my first OPUS report following removal of the tree was included in the current average NAD83(2011) position. This remains a work in progress. Over time there will be more OPUS sessions. Each time I will decide whether to include it in the average or begin again.
The OPUS reports, raw data files, and more photos are available on my projects ftp site.
The ProFlex500 can be viewed at http://72.215.9.254
Here are some before and after photos.
With the pecan tree removed the skyline looks much different.
