Base map CR 1:25,000 - colour seamless - 09800795

Since 2002, the ZM 25 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. Data are derived directly from the cartographic database Data10 of technology line IS SMD. The resolution of rasters is 800 dpi and the color depth is 24 bit. The distribution is in TIFF format (LZW compression). The export units are 5x5 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.自2002年起，ZM 25数据集基于捷克共和国地理基础数据（Fundamental Base of Geographic Data of the Czech Republic，ZABAGED®）与捷克共和国地理名称数据库Geonames的数字技术完成生产。数据直接源自技术线路IS SMD的制图数据库Data10。栅格（raster）分辨率为800dpi，色彩深度为24比特。数据以TIFF格式（采用LZW压缩）进行分发。导出单元为边缘平行于S-JTSK基准轴的5×5千米幅段。各幅段已通过针对S-JTSK Krovak EN与WGS 84 / UTM zone 33N投影的文本文件（TFW）完成对应坐标系下的地理配准。
