Base map CR 1:50,000 - colour seamless

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.

Abstract: 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.
Purpose: ZM 50 belongs to medium-scale base maps. These maps have a topographic character: they contain planimetry, altimetry and map lettering. Digital form of the medium-scale base maps is due to the advantage of unified processing for the whole territory of the Czech Republic exploited in geographic information systems, map portals and web application as an overview map.

Other information: EPSG code 5514 S-JTSK / Krovak East North is an equivalent to the existing ESRI code 102067. The projection keeps the mathematic so called "east-north" orientation of coordinate axis where the X axis has positive values eastwards and Y axis northwards. This projection is suitable for exploitation in GIS applications. The projection is related to the Greenwich Prime Meridian (contrary to the EPSG 5221 S-JTSK (Ferro) / Krovak East North where the Prime Meridian is Ferro).
