Topographic Maps and Profiles

This video tutorial explains how to create a topographic profile and calculate the gradient between two points on a map. It covers understanding contour lines, labeling elevations, using scrap paper for profile creation, and drawing a smooth curve for the profile. The video also demonstrates calculating the gradient by determining the change in elevation over a distance, emphasizing the importance of units in calculations.
