National Geodetic Survey Updates “Bluebooking” Process for GPS Projects


National Geodetic Survey (NGS)

NGS updates "Bluebooking" process for GPS projects.

Breaking news from the NOAA National Geodetic Survey (NGS) about GPS projects "Bluebooking" process:

The "Bluebooking" adjustment process for GPS projects has been revised and is now available to the public for evaluation and use. An evaluation (beta) version of the adjustment software suite (including associated documentation) is available here . The beta version should be used to submit all GPS projects to NGS; projects submitted using the previous version will no longer be accepted. The evaluation period is expected to last one to two months, and during that time NGS welcomes your questions and comments.

One comment on “National Geodetic Survey Updates “Bluebooking” Process for GPS Projects
  1. “Bluebooking”, a process of geodetic surveying introduced – you guessed it – in an actual book that was blue, has become a buzzword for any data post-processed with geodetic corrections via the National Geodetic Survey (NGS). I have actually read the “blue book” and other publications comprising it’s collective entirety as a process. I have personally “bluebooked” (of course, with direct involvement with real people in the NGS), and found the process to be burdensome, if not even impossible, mathematically to achieve the precision outlined in the various categories or levels of precision by the NGS. Notwithstanding all I have already said about the process, I must ask a serious question: What role does the NGS intend to play in the post-processing and geodetic correcting of raw data, and what difference does it make if there is no oversight by the NGS? Also, will geodetic monuments even be necessary in the near future? If not, what importance would any survey monument hold after been accounted for with geodetic precision? Imagine a system in which there would be no survey monuments, at all; no more need for driving iron pipes or bars into the ground to “monument” the boundary of a parcel of land; no more need for land title to be dependent upon survey; no more need for physical monumentation, at all; only virtual monumentation. Consider this: land title can be insured, to this day, without a survey, and in the absence of a survey performed on the ground a land title company will most likely choose to make an exemption to anything discovered by a survey of the land that would compromise the insurance policy. So, now I ask: Is a system of land ownership which relies solely upon the virtual or registered description of land a means of simplifying or complicating matters of legal title? My first thought is that it would be simplifying an already complex system of determining land boundaries. But, what about title? Which rights and/or interest in land can be actuated by a land surveyor, and which of the same can be actuated by a system in which a land owner has no option to pursue unwritten title to land? This is why we have land surveyors and attorneys who work together to help solve matters of boundary dispute. That’s all, let me know what you think about it.
