9:00 am – 4:30 pm CDT

 

Dr. Thomas H. Meyer, Ph.D.

Why use the State Plane Coordinate System (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 
This webinar is open to the public and is designed to qualify for 6.5 PDHs for professional engineers and land surveyors in most states; please refer to specific state rules to determine eligibility. 

 HalfMoon Education is an approved continuing education sponsor for engineers in Florida (Provider License No: CEA362), Indiana (License No. CE21700059), Maryland, New Jersey (Approval No. 24GP00000700) and North Carolina (S-0130). HalfMoon Education is deemed an approved continuing education sponsor for New York engineers and land surveyors via its course approval from the Practicing Institute of Engineering. Most other states do not preapprove continuing education providers or courses. 

 This webinar has been evaluated for compliance with NYS Mandatory Continuing Education requirements for professional engineers and land surveyors by the Practicing Institute of Engineering, and has been approved for 6.5 PDHs. 

 HalfMoon Education is an approved continuing education sponsor for land surveyors licensed in Indiana (License No. CE10600325), Maryland, and North Carolina (S-0130). This webinar has been registered with the Florida Board of Professional Surveyors and Mappers and has been approved by the Missouri Board of APEPLSPLA for land surveyors.  

 Attendance will be monitored, and attendance certificates will be available after the webinar for those who attend the entire course and score a minimum 80% on the quiz that follows the course (multiple attempts allowed). 

  On-Demand Credits 

The preceding credit information only applies to the live presentation. This course in an on-demand format may not be eligible for the same credits as the live presentation; please consult your licensing board(s) to ensure that a structured, asynchronous learning format is appropriate. 

Speakers

Dr. Thomas H. Meyer, Ph.D.

Professor of Geodesy, University of Connecticut

Dr. Meyer is a professor in the Department of Natural Resources and the Environment at UConn’s College of Agriculture, Health and Natural Resources (CAHNR). He is a member of the American Society of Civil Engineers and the American Society for Photogrammetry and Remote Sensing, and he is a fellow and past president (2016, 2019) of the American Association for Geodetic Surveying. Dr. Meyer is a past president (2006-2007) of the Geomatics Society of New England (previously known as the New England Section ACSM) and a member of the editorial boards of the Journal of Surveying Engineering and Surveying and Land Information Science. Dr. Meyer earned his Ph.D. degree from Texas A&M University (College Station, 1998) where he was a research associate in the Mapping Sciences Laboratory. He was named a UConn Teaching Fellow (2015), and he has taught geomatics courses at the graduate and undergraduate levels in geodesy, geographic information science, digital terrain modeling, spatial statistics, and global navigation satellite system surveying. Dr. Meyer has authored an undergraduate-level geodesy textbook and numerous peer-reviewed papers about surveying and mapping, and he teaches professional education seminars for surveyors throughout New England and the United States.
