isogonic

isogonic
Adjective

This term is a highly specialized technical descriptor used almost exclusively in geodesy, cartography, and navigation. It describes a specific geometric relationship where the angle between true north and magnetic north remains constant across a given line or area.

Because it is a precise scientific term, it lacks a casual or metaphorical equivalent. It is typically paired with nouns like line, curve, or map to describe the visual representation of magnetic declination on a chart.
