We have published a guide at work, it includes a bit about just how accurate surveys are without ground control points. That should be of interest here.
This will be released on a six month rotation and include commercial operator lists from around the world (The next one just 333's right now) I would love to know what you would like to read about in the next one, and I will try and find it!
Here's how surveyor Luke Wijnberg summed up his article.
“The uncertainty of the data issued can cause the client to make costly mistakes when doing earthworks or other quantity calculations. It is not sufficient to issue information as accurate and absolute because the processing software says it is. The surveyor needs to remember his training and apply first principles when undertaking this type of survey as there is certainly a potential for exaggerated results.”
