korkeuskuvat

Korkeuskuvat, also known as height images or digital surface models (DSM), are a type of remote sensing data that represent the elevation of the Earth's surface. These images are typically generated using aerial or satellite-based sensors, such as LiDAR (Light Detection and Ranging) or photogrammetry, which measure the height of objects and terrain features. Korkeuskuvat provide a three-dimensional representation of the landscape, including both natural and man-made features.

The primary purpose of korkeuskuvat is to capture the topographic details of an area, including the height of buildings, trees, and other structures, as well as the elevation of the ground surface. This information is crucial for various applications, including urban planning, environmental monitoring, flood risk assessment, and infrastructure development. For example, in urban planning, korkeuskuvat can help in designing buildings and roads by providing accurate elevation data.

Korkeuskuvat are often used in conjunction with other types of remote sensing data, such as orthophotos and digital elevation models (DEMs), to create comprehensive geographic information systems (GIS) datasets. These datasets are essential for a wide range of scientific, engineering, and administrative purposes. The resolution and accuracy of korkeuskuvat can vary depending on the sensor technology used and the specific requirements of the project.

In summary, korkeuskuvat are valuable tools for capturing and analyzing the three-dimensional structure of the Earth's surface. They play a critical role in various fields by providing detailed elevation data that supports decision-making and planning processes.
