A map section is a portion of a map that is divided into four parts: an INSET, a REGION, the WEST, and the EAST. An INSET is a small map or diagram included within the borders of a larger map. A REGION is an area of land with distinct characteristics, such as a geographical area or a political boundary. The WEST and EAST refer to the cardinal directions, with the WEST being the direction to the left of the map and the EAST being the direction to the right.
