pinnankorkeusmalli
Pinnankorkeusmalli, also known as the "height model" or "elevation model," is a digital representation of the Earth's surface, specifically focusing on the vertical dimension. It provides information about the height or elevation of terrain features, such as mountains, valleys, and plains, above a reference surface, typically mean sea level. Pinnankorkeusmalli is used in various fields, including geography, geology, hydrology, and urban planning.
The model is created using data from sources like satellite imagery, aerial photography, and ground-based surveys.
Pinnankorkeusmalli is essential for understanding and managing the Earth's surface. It helps in assessing flood risks,
