The digital surface model of the Czech Republic from image correlation represents a representation of the georelief including all natural and human-made objects. Natural objects include vegetation cover, while human-made objects represent buildings. The DMP, the first one created from data acquired in 2024, is created by the method of image correlation of aerial survey images acquired primarily for Ortofoto ČR. The dataset is available in the form of a point cloud arranged in a regular grid (0.2 × 0.2 m), and in a raster format (0.5 × 0.5 m), which is created by interpolation from the point cloud. The DMP from image correlation is intended for analyses of the height ratios of the georelief and objects located on it, both regional and local in nature. Typical uses include visibility analyses, modeling the propagation of radio waves, modeling the propagation of harmful substances and impurities in the air. This dataset is provided in the ETRS89-TM33N coordinate reference system and the EVRS elevation system.

The Digital Surface Model of the Czech Republic, 1st Generation (DMP 1G), represents the territory including buildings and vegetation cover as an irregular network of height points (TIN) with a total root mean square error of 0.4 m for precisely delineated objects (buildings) and 0.7 m for objects that are not precisely delineated (forests and other vegetation elements). The model was created from data acquired by airborne laser scanning of the Czech Republic between 2009 and 2013. DMP 1G is intended for analyses of terrain elevations (DMR 5G) and the geographical objects located on it (buildings and vegetation cover) at regional and, in some cases, local scales, for example in visibility analyses, radio wave propagation modelling, modelling of the dispersion of harmful substances and pollutants in the atmosphere, and generating virtual terrain views in flight simulators and training devices. This dataset is provided in the ETRS89-TM33N coordinate reference system and the EVRS vertical reference system.
