Problem: Plats and Mapping: ALTA/ACSM Land Title Survey Plats

Which type of scale on a plat is most useful, and why?

(A) A representative fraction is most useful because it is dimensionless.
(B) A ratio scale, such as 1 in = 500 ft, is most useful since such a scale is universally understood.
(C) A bar scale is most useful since it remains valid despite enlargement or reduction of the plat.
(D) An architect’s scale, such as 1/8 in = 1 ft, is most useful since it allows the representation of the greatest detail.

Answer: C
