contrastiviivat

Contrastiviivat, also known as contour lines, are lines on a map that connect points of equal elevation, representing the shape of the terrain. They are a fundamental tool in cartography and geology, providing a visual representation of the landscape's topography. Each line represents a specific elevation, with the elevation difference between adjacent lines, known as the contour interval, typically indicated on the map. The closer the lines are to each other, the steeper the terrain; conversely, widely spaced lines indicate a gentler slope. Contrastiviivat can also indicate the presence of features such as ridges, valleys, and depressions. They are used in various fields, including surveying, engineering, and environmental science, to plan and analyze projects that involve the land.
