The Basic Topographic Map of the Czech Republic 1:5 000 in the S-JTSK coordinate system (ZTM 5/S-JTSK) has extended the scale series of the national map series of the Land Survey Office since 2023. ZTM 5/S-JTSK is produced from the Fundamental Base of Geographic Data of the Czech Republic (ZABAGED®), the Digital Terrain Model of the Czech Republic, 5th Generation (DMR 5G), the Geonames database of geographical names of the Czech Republic, and the Data10 cartographic database. The data are processed in the ZTM 5 cartographic database of the IS SMD technological line. Print files containing the complete content of the map sheet are generated in PDF format (CMYK), and raster files of the map field are produced in TIFF format (RGB, 24-bit colour depth, 508 dpi, LZW compression). Data are also exported from the cartographic database in vector formats ZTM 5/S-JTSK – SHP and DGN8, allowing a certain level of editing in GIS and CAD applications. The distribution unit is a ZTM 5 map sheet, which for raster TIFF files and vector data represents a segment of 2.5 × 2 km with sides parallel to the coordinate axes of S-JTSK. For raster data, the position of segments in the coordinate system is ensured by world files (TFW) for the S-JTSK / Krovak EN display. The print PDF additionally contains coordinate grids (the kilometre grid of S-JTSK and the geographical and kilometre grid of ETRS89/TMzn), the map frame with frame data (e.g., directional information for selected roads, names of neighbouring settlements, descriptions of neighbouring countries, coordinates), and marginal information (e.g., legend, imprint data, graphical, numerical, and slope scale, graphical overview of administrative and cadastral boundaries and boundaries of protected areas). Furthermore, the map field is extended by an overlap strip of 100 m in the east and west and 50 m in the north and south. ZTM 5/S-JTSK contains planimetry, altimetry, and map lettering. Planimetry includes settlements and individual objects, transport networks, hydrography, boundaries of administrative units and cadastral units, boundaries of protected areas, points of horizontal geodetic control, vegetation, and land cover. Altimetry represents terrain relief depicted by contour lines from the ZABAGED® – Altimetry – Contour Lines product derived from DMR 5G, with a basic contour interval of 1 m, terrain steps, rock formations, gullies, landslides or scree, isolated rocks and boulders, groups and rows of stones, and spot heights with indicated elevation. Map lettering consists of generic object designations, standardised geographical nomenclature (including street names), contour labels, spot heights, and building numbers. Only objects occurring within the territory of the Czech Republic are depicted. Necessary generalisation and displacement of individual objects are applied only to a very limited extent. The map therefore provides detailed information about the defined territory with high positional accuracy while preserving the shape and size of the depicted areal topographic objects as in the source databases.
