Evolution of the National Spatial Reference System &

Using and Understanding the On-line Positioning User Service (OPUS)

Friday, September 27, 2013

Clark University MetroWest Campus, 333 Turnpike Road (Route 9 West), Southborough, MA

8:00 - 8:30 AM Registration; 8:30 AM - 4:30 PM Seminar

Evolution of the National Spatial Reference System – NAD 83 (2011) and GEOID 12

In July of 2012, the National Geodetic Survey released the latest realization of NAD 83 and a new companion geoid model. This presentation will discuss a brief history of NAD 83, and reasons for its ongoing evolution. We will discuss the data used to produce the National Adjustment of 2011 (NA2011), and the concept (and need) to introduce velocities. Also discussed will be the relationships of geoid models to various versions of NAD 83 and what can happen if these relationships are ignored.

Using and Understanding the On-line Positioning User Service (OPUS)

The national Geodetic Survey (NGS) operates the On-line Positioning User Service (OPUS) as a means to provide GPS users easier access to the National Spatial Reference System (NSRS). OPUS allows users to email their GPS data files to NGS, where the data will be processed against the Continuously Operating Reference Station (CORS) network to determine a position using NGS computers and software. This seminar will discuss:

· The history and development of OPUS products

· A discussion of OPUS accuracies (and things that affect the accuracies)

· Recommended collection procedures, data requirements, and data management

· A discussion of how to use each of the OPUS products and how they work

· An in-depth look at the output of OPUS and a discussion of OPUS statistics and quality indicators

· What can be done to make a poor solution better?

· A discussion on datums and coordinate systems for OPUS

· The recent CORS Multi-Year Solution and National Adjustment of 2011

Participants are encouraged to bring their own laptop and data. WiFi is available.
