5  Sources of LIDAR and/or DTM data

5.1 Europe

• DTM at different scale, up to 20m, based on LIDAR data for many EU countries made by Sonny; https://sonny.4lima.de/. Another very helpful site is https://www.opendem.info/, where you can find a generated 1m DTM for most of the EU. https://lidarandaerialarchaeology.com/europe/

Albania

• https://geoportal.asig.gov.al/en/services, no LIDAR data

Austria

Portugal

LAZ data for mainland part available to download after registration using Centro de Dados - DGT portal. DTM and DSM of 0.5~m and 1~m resolution also available.

Slovakia

• DTM and DSM data from two LIDAR cycles: 2017–2022 and 2023 to 2026; available for download in TIFF fomat with resolution of 0.5 m for area of whole Slovakia from 1st cycle, for some of the areas from 2nd cycle. URL: https://www.geoportal.sk/en/zbgis/als/provision-als-products/

• LIDAR data - small chunks of data (up to 4 km²) available through MAPKA application.

Slovenia

• https://gis.arso.gov.si/evode/profile.aspx?id=atlas_voda_Lidar@Arso&culture=en-US

Sweden

• LIDAR data in form of 2.5x2.5 km sqares are available for download under https://www.lantmateriet.se/en/geodata/our-products/product-list/, after account creation. The points are divided into classes:

  • land
  • water
  • bridge
  • low point (noise)
  • high noise
  • unclassified, points that are not classified in any of the other classes.

There is a terrain model in grid format as well, with coordinate-based elevation points in a regular grid with a 1-meter resolution and high elevation accuracy.
