Topographic maps are maps that illustrate the topography (vertical relief, such as hills) of the mapped region. 7.2 MAP PARTS, ORIENTATION, AND SCALEĪ map is a plan view (viewed from above, also known as map view) representation of an area on Earth’s surface. This is a critical skill to prepare students to learn about more complex geologic maps. The purpose of this chapter is to familiarize students with how to read and use topographic maps.
