Field Mark

A field mark is a distinguishing feature or characteristic used to identify or differentiate objects, often in sports, engineering, or biology. In sports, like baseball or cricket, it refers to markings on the field that shape play or boundaries. In other contexts, such as engineering or design, it can denote specific visual or structural features that help recognize or locate an object or area. Essentially, a field mark acts as a reference point or indicator that helps people easily identify, orient, or understand what they are looking at within a larger scene or system.
