Pick a Geoid Model and let TPC compute elevations and ellipse heights for you

Geoid Models

TPC now supports all NGS Geoids up through Geoid 2012A and Geoid 2012B.

You can download and install additional NGS geoids and they will show up in this list.

Of course, we still include the NGA geoids for global geoid support.
