Metria
Metria is a rarely used, and somewhat archaic, term related to measurement, particularly of the earth's surface or land surveying. The word itself implies a science or art of measurement. It's etymologically derived from Greek roots related to "measure" and is similar in function to words like "geometry" (earth measurement) and "trigonometry" (triangle measurement).
Historically, "metria" might have been used to refer to practical land surveying techniques or theoretical frameworks related to measurement systems. Its usage predates the widespread adoption of more modern terminology within surveying, cartography, and related fields. The term is not common in contemporary scientific or technical discourse. Today, terms like geodesy, photogrammetry, or land surveying are more commonly used to describe these practices and associated scientific disciplines.
Its limited usage may also stem from being a more generic term, encompassing the act of measurement itself rather than a specialized field. While related to other measurement-focused "-metry" words, the relative lack of a precise and widely accepted definition has contributed to its obscurity.
Therefore, when encountered, "metria" should be understood as a general reference to measurement or surveying practices, typically within an older or historical context.
