Problem of the Week: Map Types and Symbols

Problem of the Week

Which of the following statements does NOT correctly describe a difference between a map and a plat?

(A) A plat may function as a legal description of the land it represents in lieu of a written description. A map rarely fulfills such a function.

(B) A plat is more likely to show property boundaries than is a map. A map’s emphasis is more often on physical features.

(C) A map may contain omissions or generalizations of particular physical features. A plat generally shows all data necessary to accurately represent the land it delineates.

(D) A map is more likely to show dimensional data than is a plat. A plat usually is intended for uses where distances and quantities are determined by scaling.

A map is much more likely to depend on scaling for the derivation of distances, quantities, etc., than is a plat. A plat should show, among other things, sufficient dimensional information to make scaling unnecessary.

The answer is (D).
