Relative Positional Precision Explained in Everyday Language: (5-8 hours)

​

The 2016 ALTA/NSPS standards limit the relative positional precision of the points in your survey. Do you understand how that really works? Without using least squares adjustment software, it’s impossible to generate a realistic relative positional precision value. This seminar builds a strong foundation of knowledge that will support your least squares adjustment efforts. Join us to review the error sources in our surveys, refresh your basic statistics knowledge, and explore the impact of equipment specifications. You’ll see just how important redundant measurement truly is. Using error estimates, we’ll apply weights appropriately to adjust our measurement data. Through an example project, you’ll see the impact of redundancy, errors, and the resulting weights. We’ll dispel the mystery in least squares adjustment, show you how to interpret the results, and equip you to certify your next ALTA survey with greater confidence.

Upcoming Changes to National Datums and the Effects on State Coordinates: (2-6 hours)

​

In just a few short years, our national horizontal and vertical datums will be replaced.  Do you understand the changes well enough to explain it all to your field crews?  We’ll review the fundamentals of geometric and physical geodesy, and we’ll compare the new approach with the current ones.  Come see how changes to our state plane coordinates and elevations will alter our field methods.
