John Alexander - Topographic Maps

John Alexander’s work on topographic maps emphasizes their role in representing the Earth's three-dimensional landscape in a two-dimensional format. Topographic maps use contour lines to show elevation changes, illustrating hills, valleys, and slopes. These maps provide detailed information about terrain features, such as roads, rivers, and vegetation, making them essential for outdoor activities like hiking, planning, and land use. Understanding these maps helps users visualize the landscape's shape and navigate effectively, showcasing the relationship between natural and human-made features in a given area.
