höjddatasets
Höjddatasets, also known as elevation datasets, refer to digital representations of Earth's terrain that capture variations in surface height. These datasets are essential for a wide range of applications, including geography, environmental science, urban planning, and disaster management. Elevation data is typically collected using remote sensing technologies such as LiDAR (Light Detection and Ranging), satellite altimetry, and photogrammetry, as well as through traditional surveying methods.
LiDAR is one of the most precise methods for acquiring elevation data, using laser pulses to measure
Höjddatasets are commonly distributed in formats such as DEMs (Digital Elevation Models), DSMs (Digital Surface Models),
Publicly accessible höjddatasets, such as those from NASA’s Shuttle Radar Topography Mission (SRTM) or the European
