Tech Talk: When is Surveying Considered Mapping

December 2, 2011
It never fails--when I conduct a seminar and ask “who’s a surveyor?” most hands go up. Then I ask “how many of you do mapping?” and very few hands go up, maybe 2 percent to 5 percent of the room. To me, these responses demonstrate the lack of vision or breadth in the opinion that many surveyors possess about their work and their profession.

Tech Talk: A Vision for Photogrammetry

October 27, 2011
Photogrammetry is a catch-all term for making all kinds of measurements from photographs. For many surveyors, photogrammetry has evolved into a process that seems a bit like “black art.”

Tech Talk: Should You Be Using GNSS?

July 20, 2011
GPS is considered a key technology by most surveyors. In trend studies such as POB’s annual Salary & Benefits Study, GPS continues to be cited as one of the technologies having the biggest impact on the profession more than 30 years after its initial introduction.

Tech Talk: State Plane Coordinates

July 5, 2011
There was a time (in the 1980s and prior) when “everyone” knew about State Plane Coordinates (SPCs), including how those systems were set up and how to use them effectively.

Tech Talk: Why Geodesy Matters

April 27, 2011
“Geodesy” and “geodetic” are terms many plane surveyors love to ignore. As long as surveys are performed over small areas and/or the accuracy requirements are such that disregarding the curvature of the earth is an adequate simplification of the world, ignorance is feasible.

The Questionable Future of GPS

March 25, 2011
Technological change can bring dramatic improvements, even in surveying. But a key part of moving ahead is that new technologies should only displace others if they are replacement technologies. Today, a looming communications technology threatens to doom GPS, a crucial positioning (and timing) technology, by displacing it without providing an alternative.

Tech Talk: Metadata

February 25, 2011
The term metadata has been around for a while. Among certain geospatial professionals, this term, what it means and how it relates to them is intrinsic to their practice. For other professionals, metadata is part of what they do, but they don’t think of it as metadata, nor do they make a big deal about it.

Tech Talk: Calibrating Equipment

January 25, 2011
I fully subscribe to A.C. Mulford, who wrote in his 1912 Boundaries and Landmarks: A Practical Manual: “For after all, when it comes to a question of the stability of property and the peace of the community, it is far more important to have a somewhat faulty measurement of the spot where the line truly exists than it is to have an extremely accurate measurement of the place where the line does not exist at all.” But we must be careful how we use this quote.
