Základní topografická mapa České republiky 1 : 5 000 v ETRS89

The Base Topographic Map of the Czech Republic 1:5 000 in the plane coordinate system of the European Terrestrial Reference System 1989 in the Universal Transverse Mercator projection of meridian zones (ETRS89-TMzn), hereinafter referred to as ZTM 5/ETRS89, extends the national map series from 1 January 2026 with a variant of ZTM 5 in the plane coordinate system ETRS89-TMzn, as an alternative to ZTM 5 in the national coordinate system S-JTSK. In terms of content, ZTM 5/ETRS89 does not differ from the primary ZTM 5/S-JTSK. ZTM 5/ETRS89 covers the entire territory of the Czech Republic in a continuous map layout; the territory of the Czech Republic is shown on 18 287 map sheets. The sheet lines of the layout (inner frames) of the ZTM/ETRS89 map sheets form images of meridians and parallels at a specified spacing dependent on the map scale. A ZTM 5/ETRS89 map sheet thus covers an area of 1′ × 2′ (latitude × longitude). The dimensions do not include the accompanying elements shown on the printed version of the map sheet (i.e. the boundary band and frame and non-frame data). The dimensions of the printed map including all frame and non-frame data are 480 mm × 770 mm. ZTM 5/ETRS89 map sheets are identified by a nomenclature of alphanumeric character derived from the designation of the International Map of the World 1:1 000 000 (NM-33 and NM-34 for the Czech Republic), covering 6 degrees of longitude and 4 degrees of latitude. Additional characters specify the position of the map sheet of a given scale within the map sheet of the smaller scale from which it is derived. The map sheets are further supplemented by a map sheet name, which is generally identical to the name of the largest settlement on the given map sheet; in the case of ZTM 5/ETRS89, ZTM 10/ETRS89 and ZTM 25/ETRS89 this is the name of the corresponding ZTM 50/ETRS89 map sheet. If no settlement is found on a map sheet, another unique geographical name (peak, watercourse, land tract) from that map sheet is used. ZTM 5/ETRS89 map sheets are created by dividing a ZTM 10/ETRS89 map sheet into 4 map sheets using 2 rows of 1 minute of latitude and 2 columns of 2 minutes of longitude, numbered consecutively within the ZTM 10/ETRS89 map sheet in rows from the north-west map sheet as 1, 2, 3, 4. An example of a map sheet designation is Žďár nad Sázavou NM-33-08-6-B-20-1. ZTM 5/ETRS89 contains planimetry, altimetry and descriptions. The planimetry includes settlements and individual objects, roads, hydrography, boundaries of administrative units and cadastre units, boundaries of protected areas, geodetic control points, vegetation and land surface. The altimetry includes terrain relief shown by contour lines and terrain steps. The map description consists of feature type designations, standardised geographical nomenclature (including street names), contour line elevations, points with given elevation and building numbers. Only features occurring within the territory of the Czech Republic are shown. Necessary generalization and displacement of individual objects are used very sparingly. The map thus provides detailed information about the defined area with high positional accuracy, preserving the shape and dimensions of the depicted areal topographic objects as in the source databases. The printed map sheets also contain the ETRS89-TMzn and S-JTSK one-kilometre map grid and the ETRS89 geographical grid, a map frame with frame data (e.g. directional data for selected roads, names of shared settlements, descriptions of neighbouring states, coordinates) and non-frame data (e.g. map legend, imprint data, graphical, numerical and gradient scale, interpolation scale of the ETRS89 geographical grid, graphical representation of the map in the map layout, expression of meridian convergence and magnetic declination, graphical representations of the overview of administrative and cadastral boundaries and boundaries of protected areas, etc.).
