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.

Member Spotlight

PLSC would like to introduce you to our members. If you would like to submit your photo and information for a future Spotlight, email the information to

Earl F. Henderson, PLS, started his survey career with a brief term of employment in Maryland
before gratefully spending nine more years in the colloquial system of surveying in the shadow of the Blue Ridge Mountains in Central Virginia. In 1999 he moved to Boulder and the PLSS. He became licensed to survey in the State of Colorado in 2000. After five years of employment in an engineering/surveying firm in Boulder he started his own business, Zenith Land Surveying, in 2004. He remains happily a “solo surveyor”. He has been a staff writer for Professional Surveyor Magazine since 2004 writing fictional stories under the byline “The Humor in Surveying” and
“Gigglebytes” while recently venturing into non‐fiction. He has also been a contributing writer to Side Shots with his recent
contributions there about the Colorado State Statutes and Board Rules. Earl was appointed by Gov. Hickenlooper to the AES Board at DORA in 2011 and is currently serving as Board Chair.
