This week, the National Geodetic Survey's Corbin Training Center held an Astronomic Azimuth Workshop. At the event, surveyors and subject matter experts from around the nation received hands-on instruction. Azimuth determination is a critical element of every survey. The astronomic azimuth method is quick, accurate, inexpensive, and-because it is independent of the Global Positioning System (GPS)-it can further be used to validate or verify GPS-derived azimuths.
