Maastonmalliin

Maastonmalliin refers to a digital representation of the Earth's surface topography. This data can take various forms, most commonly a Digital Elevation Model (DEM) or a Digital Surface Model (DSM). A DEM typically represents the bare ground elevation, excluding vegetation and buildings, while a DSM includes the elevation of surface objects. These models are created using remote sensing techniques such as aerial photography, satellite imagery, LiDAR (Light Detection and Ranging), and photogrammetry.

The primary applications of maastonmalliin are found in fields like geographic information systems (GIS), urban planning, environmental studies, and engineering. They are crucial for tasks such as topographic mapping, hydrological modeling to predict water flow and flood risk, landscape analysis, and the planning of infrastructure projects like roads and buildings. Maastonmalliin data allows for the creation of 3D visualizations, accurate slope and aspect calculations, and the simulation of terrain modifications. The precision and resolution of maastonmalliin vary depending on the data acquisition method and the intended use.
