meridiaanist

A meridiaanist is a person who studies, advocates, or works with geographic meridians, the longitudinal lines used to define coordinates on the Earth and to organize navigation, mapping, and timekeeping. The term is informal and not widely standardized in professional geodesy or cartography, and its usage varies by language and region. In many contexts, a meridiaanist would engage with concepts related to longitude, the prime meridian, and the global coordinate system, as well as the practical applications of these lines in surveying, GIS, and satellite positioning.

Etymologically, meridiaanist derives from meridian, the Latin-based term for a half-circle connecting the North and South Poles, combined with the suffix -ist to denote a practitioner or advocate. Historical reference to meridians appears in cartography and astronomy, where meridians helped define time zones and cadastral boundaries as well as navigation routes. Today, discussions about meridians often intersect with modern geospatial technology, such as global navigation satellite systems, digital map projections, and geographic information science, though the label meridiaanist itself remains uncommon in formal curricula or professional titles.

In contemporary use, a meridiaanist might be a researcher, educator, or enthusiast focusing on meridian-based concepts, or someone who studies the historical development of longitude and prime meridians. Related terms include meridian, longitude, prime meridian, and cartography. The concept is primarily of historical and practical interest in geography and GIS rather than a widely recognized professional designation.
