G33B:
Modernizing Regional Reference Frames and Vertical Datums for North America I Posters


Submit an Abstract to this Session


Session ID#: 50738

Session Description:
In 2022 the existing non-geocentric reference frames of North America will be succeeded by a set of modern ones using the latest realization of ITRF that is fixed separately to the North American, Caribbean, Marianas and Pacific tectonic plates. In addition, all leveling-based vertical datums will be replaced with a geoid-based datum incorporating continental airborne gravity and new global geopotential model. Contributions are invited that address the development, implementation and maintenance of such regional reference frames, including: defining a geocentric reference system fixed to a moving and deforming continent, defining a geoid-based vertical datum, implementing time dependencies including geoid change, creating accurate transformations, defining the role of private Real-Time Networks, determining dynamic heights, building geospatial databases capable of handling historic static data along with modern time-dependent data, and collaborations with neighboring countries to ensure compatible and seamless reference systems across the continent.
