Gavin Schrock, PLS

Associate Editor


Gavin Schrock, PLS is a surveyor, technology writer, and operator of a cooperative GNSS network (RTN). Originally from PA, Gavin spent most of his youth in Australia, then worked in AK, AZ, HI, CO, CA, and a few other places that sometimes he can’t remember before settling in the Pacific Northwest, where he is viewed as a relatively harmless survey geek. He tried his hand at standup comedy, but someone told him he wasn’t funny and should take up surveying. He has worked in surveying, mapping, data management, GNSS, and GIS for more than three decades in the civil, utility, defense, and mapping disciplines. He has published in these fields and has taught these subjects at local, state, national, and international conferences.

Dave Doyle

Geodesy Editor

I have been engaged in geodetic surveying since my enlistment in the U.S. Army in July 1967. Following a tour with an Army topographic engineer[NL1]  company in Germany, in 1970 I was employed by a small surveying firm near Washington D.C, while I attended undergraduate school in geodesy at George Washington University. 

I joined the National Geodetic Survey (NGS) in August 1972.  My duties included a wide array of field and office activities that kept me in constant connection with the surveying, mapping, and GIS communities. I served in the position of NGS chief geodetic surveyor from 2000 until my retirement in early 2013.  In that position I was challenged with efforts to keep the various elements of the National Spatial Reference System  up to date with contemporary measurement technologies and advise NGS management on improvements to a variety of products and services aimed at ensuring the highest possible positional integrity.

Because positioning services and technologies will continue to improve and become more cost-effective and ubiquitous, I believe the roles of surveyors are being challenged in many areas. Regrettably, training in the fundamentals of geodetic reference systems has not generally been a part of the educational or practical process leading to surveying professional licensure and is an area of technical weakness for many in the profession.

I believe that those who aggressively support improved technical, professional development and engage in active participation with their local survey chapters, as well as state, national, and even international surveying associations, will guide the direction of the profession into the future.
