Gavin Schrock, PLS is a practicing surveyor, technology writer, editor of xyHt Magazine, and operator of a cooperative GNSS network (RTN). Originally from PA, Gavin spent most of his youth in Australia, then worked in AK, AZ, HI, CO, CA, and a few other places that sometimes he can’t remember before settling in the Pacific Northwest, where he is viewed as a relatively harmless survey geek. He tried his hand at standup comedy, but someone told him he wasn’t funny and should take up surveying. He has worked in surveying, mapping, data management, GNSS, and GIS for more than three decades in the civil, utility, defense, and mapping disciplines. He has published in these fields and has taught these subjects at local, state, national, and international conferences. 


Topic 1:

Network RTK Best Practices

Network RTK is an advanced form of RTK, and the same best practices apply to yield repeatable and reliable results. But there are differences ranging from subtle to significant. In many instances base-rover RTK is the better option – but in many more instances network RTK (NRTK) offers enhanced capabilities over broader areas.

This session will cover the science of space-based positioning, and the fundamentals of how real-time networks (RTN) – infrastructure and geodetic references - are developed, are maintained, and operated. The course is taught in generic and non-brand-specific terms – the fundamentals are all the same. Standard RTK best practices will be reviewed with emphasis on NTRK how to leverage the strengths of NRTK and to recognize weaknesses. We’ll cover how the use of multiple solutions; PPK, PPP, PPP-RTK, conventional post-processing can, and should be applied to achieve and test quality of results. Recent advances in the science of space-based positioning and what might be in store for RTN in the near and distant future will also be examined.

Topic 2:

A Future Fit Surveying Profession
Markets for surveying services have changed; some legacy markets have contracted while others have boomed – unfortunately often without our noticing them. More pronounced than the changes in the surveying profession are the changes to world the profession inhabits and serves. Welcome to the millennial world: clients want more, they want it now, they want richer data - and they want things that we did not even know existed a few short years ago.
U.S. surveying has had to ride the dips and peaks of dramatic demographic and economic shifts and this has presented challenges in succession planning. Changes have also challenged the authoritative roles surveyors have traditionally filled in the development and management of the built and natural environments.
What are the trends in education, technology, policy, perception and markets that will mold the future of the profession – and how has the profession responded? The presenter has worked in and written about numerous aspects of surveying for several decades and views the future of the profession as one of both challenges and opportunity – new, exciting and sometimes surprising opportunities. This session will be interactive, challenge conventional wisdom, poke a little fun, and hopefully provides some insights from “fields afar”.

NSPS strives to establish and further common interests, objectives, and political effort that would help bind the surveying profession into a unified body in the United States.

Governance: The National Society of Professional Surveyors Inc. is governed by a Board of Directors. The NSPS Board of Directors meets twice per year.   NSPS has working agreements with state surveying organizations which are represented on the NSPS Board of Directors, and with the NSPS Foundation, Inc.
