Remembering Ken Wilson
Posted June 24, 2016

It is with sadness that we share that long-time SGM employee and founder of SGM's professional land surveying department, Ken Wilson, PLS, passed away last Friday evening. Ken fought a very long, courageous battle with cancer and will be greatly missed.Ken will forever be a member of the SGM family. He was soft-spoken, kind, and a well-respected consummate professional. For those of you who did not have the good fortune to have worked with Ken, he had a brilliant mind for surveying. He developed numerous large, complex plats over the years as the Roaring Fork valley went through a development transformation. Ken pioneered plat creation through the use of special survey software and AutoCAD versus old-school pen and ink. In SGM's role as Town Engineer, Ken reviewed the legal descriptions for more plats than probably any other surveyor in Garfield County history.Ken was passionate about quality work. For many years, he led SGM's quality control efforts and elevated the performance of those around him. He had the respect of every land use attorney and title company in the valley. Ken was the go-to guy whenever there was a contentious legal boundary dispute that required an intimate knowledge of Colorado survey law. Ken's State of Colorado PLS stamp #15710 is still today recognized by many local surveyors, engineers and professionals as a symbol of quality.SGM and the community will miss Ken greatly. Our thoughts and prayers are with the Wilson family.

Geodetic Certification Program
Posted February 28, 2016

The American Association for Geodetic Surveying (AAGS) is in the early stages of pursuing development of a Geodetic Certification Program at the request of NSPS and ASPRS. As part of that process, AAGS created an online survey. The purpose is to raise awareness of the proposed program and identify the required depth of geodetic knowledge. More information can be found on the survey web page at Feel free to share the survey link with any other geospatial professional organizations or individuals. The program is being developed in cooperation with other organizations, so you may receive (or have received) additional announcements. Please forgive any multiple postings. Thank you in advance for your willingness to participate in this important survey! Best regards,Michael L. Dennis, RLS, PEChair, AAGS Geodetic Education and Certification Committee

In 1954 Gaby Neunzert came to the U.S. from Switzerland by way of Beirut, Lebanon. Following a 3 year side trip with the U.S. Army, Gaby graduated from the Colorado School of Mines in Petroleum Engineering. After graduation, a missile job and a Master of Science in Petroleum Engineering, Gaby was given the opportunity of a lifetime when in 1979 he was asked to start and also teach the surveying program at Red Rocks Community College. Ten years later came the call to teach surveying, and other topics in the Civil Engineering option at Mines. From 1991 until his retirement in 2000 as Professor Emeritus, he wrote an extensive GPS text, as well as several surveying manuals. Gaby is a retired licensed surveyor in Colorado. For the near future, Gaby would like to share his knowledge of surveying, GPS and general knowledge with as many people as possible. Since retirement from Mines, Gaby has written a book entitled “Subdividing the Land” and has been involved in speaking at workshops.
