A scientist who practices geodesy, the branch of mathematics and earth science concerned with measuring Earth's shape, size, and precise locations on its surface.
From Greek 'geodaisia' (land measurement) plus '-ist' (practitioner). Used since the 17th century for surveyors and mathematicians studying Earth's dimensions.
Before GPS, geodists were the detectives of the planet—using trigonometry and surveying chains, they slowly mapped out Earth's true shape and proved it wasn't a perfect sphere but slightly flattened at the poles.
