January 7th
8:30 a.m. – noon: Introduction to Geodetic Leveling, GPS, and Tidal Theory
▫ This is recommended for attendees that do not have prior knowledge of basic Geodetic leveling techniques and/or using GPS for obtaining accurate heights. Basic tidal theory will also be addressed. This information is important for understanding the material to follow. If you are already familiar with these concepts, you can join the meeting after lunch. Instructors: Charlie Geoghegan (NGS) and Stephen Gill (CO-OPS)
Noon – 1:00 p.m.: Lunch
1:00 p.m. – 5 p.m.: Introduction to Tidal and Geodetic Vertical Datums
▫ This class focuses on defining vertical datums, and on the relationship between tidal datums, the North American Vertical Datum of 1988 (NAVD88) and the National Geodetic Vertical Datum of 1929 (NGVD29). Topics include: Definitions of NAVD 88, NGVD 29 and the various tidal datums, tidal datum computation methods, datum applications, improvement of the vertical component from GPS observations, National Ocean Service (NOS) tidal stations, collecting tidal data relative to a local suite of bench marks, and the National Tidal Datum Epoch. Instructors: Dave Doyle (NGS) and Allison Allen, Chenglin Gan, William Sweet (CO-OPS)
January 8th
8:30 a.m. – noon: Introduction to Tidal and Geodetic Vertical Datums
▫ Continuation. Instructors: Dave Doyle (NGS) and Allison Allen, Chenglin Gan, William Sweet (CO-OPS)
Noon – 1:00 p.m.: Lunch
1:00 p.m. – 5 p.m.: Tidal Datum Computation
▫ This is a highly technical and hands-on segment, aimed for those with a working interest in tidal datum computation methods. Multiple methods will be discussed. Instructor: Chenglin Gan, William Sweet, and Stephen Gill (CO-OPS)
Class size:
▫ 40 for Introduction to Geodetic Leveling, GPS, and Tidal Theory and Introduction to Tidal and Geodetic Datums
▫ 15 for the Tidal Datum Computation, since each attendee will have a computer workstation
