Geological map of the Czech Republic 1 : 500,000 – INSPIRE harmonized (theme Geology)

Geological Map of the Czech Republic 1 : 500,000 published in 2007, modified to be INSPIRE-compliant (cut-out for the area of the Czech Republic, harmonized data).

fullfillment of the requirements of the INSPIRE directive

HVD High value dataset. GML Dataset is distributed using GML. Atom Feed Dataset is distributed using Atom Feed.

INSPIRE theme Orthoimagery (OI)

The INSPIRE Orthoimagery data are harmonised according to INSPIRE implementing rules. The dataset contains data from 2023 and 2024. The source dataset is the Orthophoto of the Czech Republic (Ortofoto ČR). The raster image has a ground sample distance of 0.125 m. Positional accuracy is characterised by a mean positional error of approximately 0.20 m. In accordance with the INSPIRE Orthoimagery data specification, the source data have been transformed into the ETRS89-TM33N coordinate reference system. The data are provided in JP2 (JPEG 2000) format. The distribution unit is a 2 × 2 km square.

Orthophoto of the Czech Republic

Digital seemingly seamless orthophoto of the Czech Republic in a 8-bit color scale. The pixel of the raster image Ortofota ČR displays 0.125 m of the area in the middle plane of the terrain. The positional accuracy of the Orthophoto of the Czech Republic, expressed as the mean positional error, has been improving over time. In 2021–2022, this value reached 0.19–0.20 m, and in 2023–2024, it reached 0.18–0.19 m (see Technical Report on the Orthophoto of the Czech Republic). Orthofoto ČR is distributed in graphic raster formats JPG in dispensing units with a size showing 2.5 x 2 km of terrain in the SM 5 clade. The file data is provided in JPEG format and supplemented with JGW files for the S-JTSK, ETRS89-TM33N and ETRS89-TM34N coordinate systems. The files are compressed (ZIP) for download.

ZABAGED® - Altimetry - contours

The contour lines were derived from the Digital Terrain Model of the Czech Republic, 5th Generation (DMR 5G). The basic interval is 1 m, with an attribute distinguishing index contour lines at an interval of 5 m. In flat terrain, supplementary contour lines at an interval of 0.5 m are added. Given the requirements for universal use in 3D visualisation across a wide range of GIS and CAD software, the contour line objects in this dataset are represented by a three-dimensional vector spatial component with coordinates X, Y, H. The altitude H in the Baltic Vertical Datum – After Adjustment (Bpv) is also stored as the attribute "HEIGHT", providing additional options for labelling contour lines when creating maps. The dataset further contains a supplementary layer of form lines, represented by a two-dimensional vector spatial component with coordinates X, Y. Contour lines are not intended for terrain analyses (e.g., visibility, slope, aspect); for these purposes, it is recommended to use the DMR 4G or DMR 5G products.
