Contour lines were derived from the Digital Terrain Model of the Czech Republic of the 5th generation (DMR 5G). The dataset consists of 3 contour feature types with a basic interval of 1 m, which are represented by a three-dimensional vector spatial component with coordinates X, Y, H (H represents an elevation in Baltic Vertical Datum - After Adjustment (Bpv) coordinate reference system, and of an additional layer with fall lines and a label of contour lines. The dataset can be used as a background for cartographic visualisation of contour lines in the map.
