Dr. Thomas H. Meyer, Ph.D.
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
Latitude and longitude
Heights: gravity, the geoid, and Gauss
The Inferno: distances (slope, geodesic, horizontal, topographic enlargement)
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
• The forward problem
Worked out examples
• Using total-station data
• Some interesting case studies
Each webinar session earns continuing education credit and can be registered for individually. All attendees must log-on through their own email – attendees may not watch together if they wish to earn continuing education credit. HalfMoon Education Inc. must be able to prove attendance if either the attendee or HalfMoon Education Inc. is audited.
Certificates of completion can be downloaded in PDF form upon passing a short quiz. A link to the quiz will be sent to each qualifying attendee immediately after the webinar. The certificate can be downloaded from the Results page of the quiz upon scoring 80% or higher.
Webinars are presented via GoToWebinar, an easy-to-use application that can be run on most systems and tablets.

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.
