korkeuskarttojen

Korkeuskarttojen refers to elevation maps or topographical maps in Finnish. These maps visually represent the three-dimensional shape of the Earth's surface. They are essential tools in various fields, including geography, geology, surveying, and outdoor recreation.

The primary feature of a korkeuskartta is the use of contour lines, also known as isohypses. Each contour line connects points of equal elevation above a specific reference level, typically sea level. The closer the contour lines are to each other, the steeper the terrain. Conversely, widely spaced contour lines indicate gentler slopes.

These maps often include other important information such as spot elevations, which are exact height measurements at specific points, and relief shading, which uses tones of gray to simulate the appearance of hills and valleys, enhancing the visual representation of topography. Water bodies like lakes and rivers are also clearly marked.

Korkeuskarttojen are created using data from surveys, aerial photography, and digital elevation models (DEMs). They play a crucial role in planning infrastructure projects, understanding landforms, assessing flood risks, and navigating in natural environments. Hikers, mountaineers, and other outdoor enthusiasts rely on them for route planning and safety.
