Boundary Lines: When a Fence Appears in the Middle of your Street
In early July 2014, the residents at the end of Eastside Drive, a tranquil community of lakeside homeowners in Cobb County, Georgia, were perplexed to see workers installing a fence, ostensibly down the middle of their paved road. When the fence was completed, and where homeowners once enjoyed the ability to back up their vehicles...
The Next Generation: FIG’s Young Surveyor’s Network
We are writing at the end of 2013, when geographic information and spatial thinking, both essential for the surveying profession, are increasingly part of our daily lives and jobs. The availability and the speed with which we can connect and use this geographic information, and even our way of spatial thinking, has changed dramatically in...
Business Angle: Hardware and Software Purchase Decisions
Hardware and software purchases are two of the largest expenses, outside of personnel, for surveying professionals. There was a time when a surveyor could purchase a high-quality instrument and expect to use it for a decade or more. When I was first sent out to perform field surveys, I (as the new guy) got the...

I believe I made a miscalculation—the “future” is progressing very rapidly, and a lot of what I envisioned is already here. Here are several notable examples. Locata, the Australian-based company that developed their terrestrial-based replication of the GNSS...
Where Theory Meets Practice: Geodetic Observations – Part 2
Part 1 of this article (March 2014) presents the differences between azimuths that surveyors observe with a total station and the geodetic azimuths listed in GNSS adjustment reports. However, the effect on angles caused by the deflection of the vertical at the observing station is typically small. Thus, the difference between the observed astronomic angle and...
