The ''reference system'' is a fundamental requirement for any issue related to spatial positioning, and the ''datum'' serves as the basis for all measurement and cartography work. According to the customary terminology in international academia, the ''reference frame'' is the realization of the ''reference system.'' What are the similarities and differences between ''reference frame'' and ''datum,'' or between ''reference system'' and ''datum''? This paper attempts to explore the meanings and applications of these three terms through a review of the literature and, from there, discuss the evolution of thought regarding ''reference systems,'' ''reference frames,'' and ''datums'' in the process of modernization. Although the meaning of ''system'' adopted in the international academic community is quite clear, in domestic academic terminology, as represented by the National Land Surveying and Mapping Act, the term ''reference system'' carries an opposite connotation. This paper aims to clarify this distinction as well. The use of terminology is rooted in tradition and culture. If the definitions are clear, there are no misunderstandings, and thus no right or wrong. The purpose of this paper is merely to explain the background meaning, not to debate what is right or wrong. |
