Since 2002, the ZM 50 is produced using digital technology from the Fundamental Base of Geographic Data of the Czech Republic (ZABAGED®) and the database of geographic names of the Czech Republic Geonames. The data are derived directly from Data50 cartographic database of IS SMD technology line. These files are by the application server service rasterized with resolution of 800 dpi, 24 bit colours and unified raster palette. The distribution is in TIFF format (LZW compression). The export units are 10x10 km segments with edges parallel to S-JTSK datum axes. Segments are georeferenced in the coordinate system using text files (TFW) for S-JTSK Krovak EN and WGS 84 / UTM zone 33N projections.
