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

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

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

How to Map in the SPCS 
o Directly from geodetic: USACE CORPSCON, NGS State Plane Tool
o From total-station observations
reductions
the forward problem
o Worked out examples
using total-station data
some interesting case studies

Speakers

Dr. Thomas H. Meyer Ph.D.

Thomas H. Meyer, Ph.D. Professor of Geodesy in the Department of Natural Resources and the Environment at the University of Connecticut 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.
