Spatial Networking for Fun and Profit
Recently I attended a UAV event in my area (watch for the July issue of xyHt for more) that got me thinking about the role of networking in our profession. Not RTK, CORS, or even WANs or LANs, but person-to-person networking. Networking for fun. Meeting new people in the geospatial profession (and especially those interested...
UAS & The Combo that Opens Access
The most logical integration of technologies for surveyors is combining 3D laser scanning with UAVs. It’s no secret that many geospatial professionals are enamored with unmanned aerial systems (UAS). For many years, the pros and cons of deploying small UAS for mapping and surveying, along with their ongoing regulatory discussions, have been well researched and...
Mentoring: A Two Way Street

Mentoring, or the lack thereof and what to do about it, may be the most widely discussed topic in our profession these days, from discussion forums, to professional associations, to the...
The Certified Theoretical Monument
Igor Kidinsky, aka Eager (The Kid), estimated that both monuments—for the same property corner—were to be found nearby. Glenny Dale, aka Glutton (The Old Man), turned on the metal detector, but both surveyors soon spotted the old, grayed stakes in the shadows and knew they had found their pins. The task was to determine which...
A Correctly Weighted Least Squares Adjustment, Part 4
Correct Weights In previous articles (January, February, and April 2016) I discuss the unreliability of standard deviations when they are computed from a small sample of observations and their use in developing the stochastic (weight) model for a least squares adjustment. This is followed with how to: (1) estimate errors in centering an instrument over...
