The National Geodetic survey has been measuring land to determine points on the ground and the angles, distances, and heights between them since the 1800s. To do this accurately, you have to understand the force of gravity. We talk with a NOAA geodesist to understand what gravity is, why and how it changes, and what it means for NOAA.
