9:00 am – 4:30 pm CST

 

Presented by:
Dr. Thomas H. Meyer, Ph.D.

Agenda
Why use the SPCS
Local (ad hoc) coordinates are mutually incompatible
When we want to stitch ad hoc maps together, we discover problems
Maps cannot depict Earth’s surface without distortion

Geodesy
Latitude and longitude
Earth’s shape
Reference ellipsoids
Heights: gravity, the geoid, and Gauss
The Inferno: distances (slope, geodesic, horizontal, topographic enlargement)

Map Projections
Rectangular, Plate Carreé
Conformal and authalic
Distortions in distances and directions
State Plane Coordinates

How to Map in the SPCS
Directly from geodetic: USACE CORPSCON, NGS State Plane Tool
From total-station observations
• Reductions
• The forward problem
Worked out examples
• Using total-station data
• Some interesting case studies

Continuing Education Credit Information
Using the State Plane Coordinate System
This webinar is open to the public and offers 6.5 PDHs to professional engineers and land surveyors in most states. Land surveyor course approval is currently pending in Missouri and Tennessee. No credit is offered to land surveyors licensed in Delaware, New Jersey, New York, or Rhode Island, or for engineers licensed in New York.

The Florida Department of Agriculture and Consumer Services has assigned this course number 10223 for Florida surveyors.

Speakers

Dr. Thomas H. Meyer Ph.D.

Tom Meyer was awarded a Ph.D. from Texas A&M University in College Station, Texas in 1998, where he was a research associate in the Mapping Sciences Laboratory. He now is a Professor of Geodesy in the Department of Natural Resources and the Environment at the University of Connecticut, where he teaches courses in geomatics, GNSS and plane surveying, geodesy, and geospatial analysis in Python. Dr. Meyer is a member of ASCE and the Connecticut Association of Land Surveyors. He is also a past president of the New England Section of the ACSM and a Fellow and the 2016/2019 president of the American Association for Geodetic Surveying. Dr. Meyer has published an undergraduate textbook on geodesy, numerous peer-reviewed journal articles, and is on the editorial boards of the Journal of Surveying Engineering (JSE) and Surveying and Land Information Science (SaLIS). He is a regular presenter at national meetings, giving workshops and seminars on numerous topics in geodesy, GNSS, and surveying. His most recent research projects include new formulations of low-distortion projections, and developing spatial statistical animal-movement models for mountain lions, bobcats, and salmon.
