How to Calculate Gradient, Vertical Interval and Horizontal Equivalent | Geography Mapwork

Learn how to calculate gradient, vertical interval and horizontal equivalent in Geography mapwork using a simple step-by-step method. In this lesson, we explain how height is shown on a topographic map using contour lines, spot heights and trigonometrical beacons. You will learn how to calculate vertical interval, how to calculate horizontal equivalent using map scale, and how to write gradient correctly as a ratio. This lesson is useful for CAPS Geography learners preparing for mapwork tests and exams. Download the notes here: TBA Try the practice questions before the answers appear. This will help you check whether you can calculate VI, HE and gradient on your own.
