Creating a new Digital Elevation Model for Slovakia

Progress towards a developing a new Digital Elevation Model (DEM) for the whole of Slovakia continued in 2019.

The six-year project will create the new DEM 5.0 from airborne laser scanning data. The laser scanning and following post-processing of data is carried out by private companies with quality control independently performed by the suppliers and the Geodesy, Cartography and Cadastre Authority.

Currently, 17 of the 42 localities, which are known as lots and covering the whole territory, have been completed and published via the authority’s geoportal. Individual lots are scanned separately and the process of laser scanning goes from the west of the country to the east. All the products created from the airborne laser scanning data are provided free of charge.
