ZTM 100/ETRS89 was created in 2023 from ZTM 100/S-JTSK as an extension of the national map series to include the ZTM 100 variant in the ETRS89-TMzn plane coordinate system. It is available as print files in PDF format (CMYK) containing the complete content of the map sheet, and in raster TIFF format (RGB, 24-bit colour depth, 508 dpi, LZW compression). The distribution unit is the ZTM 100/ETRS89 map sheet. In the case of the print PDF, the map sheet size is 500 × 790 mm. In the case of the raster TIFF tile, the segment size is 411 × 522 mm. The position of individual tiles in the coordinate system is ensured by world files (TFW).
ZTM 100/ETRS89 belongs to the national map series at medium scales. These maps are topographical in character and contain planimetry, altimetry, and map lettering. The digital form of the medium-scale national map series benefits from uniform processing for the entire territory of the Czech Republic and is used in geographical information systems, map portals, and web applications. Given the level of detail and degree of generalisation, ZTM 100/ETRS89 is intended primarily for the study and assessment of the geographical environment at the level of a higher territorial unit or in national and cross-border contexts, for the preparation of territorial development policies at national level, for strategic and conceptual planning and design of territorially extensive structures and construction projects, for environmental protection policy planning, and similar purposes.

The Base Topographic Map of the Czech Republic 1:100 000 in ETRS89 (ZTM 100/ETRS89) extends the national map series with a variant of ZTM 100 in the plane coordinate system ETRS89-TMzn, serving as an alternative to ZTM 100 in the national coordinate system S-JTSK. ZTM 100/ETRS89 is produced by transforming ZTM 100/S-JTSK data, followed by data quality control and the addition of marginal and extramarginal information. The source data for ZTM 100/S-JTSK are the Fundamental Base of Geographic Data of the Czech Republic (ZABAGED®) and the Database of Geographical Names of the Czech Republic (Geonames). The data are processed in Esri FGDB and subsequently exported to PDF print files (CMYK) with the complete content of each map sheet and TIFF raster files in RGB colour space with 24-bit colour depth, 508 dpi resolution, and LZW compression.
