Base map CR 1:25,000 - colour seamless - 11200450

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数据集以捷克共和国基础地理数据基础库（ZABAGED®）及捷克共和国Geonames地名数据库为数据源，依托数字技术完成生产。数据直接取自IS SMD技术线路的Data10制图数据库。该数据集栅格分辨率为800dpi，色彩深度为24位，发布格式为TIFF（采用LZW压缩）。其导出单元为边长平行于S-JTSK基准坐标轴的5×5千米格网区块，上述区块通过文本文件（TFW，TIFF世界文件）分别在S-JTSK Krovak东北投影与WGS 84 / UTM第33N带投影坐标系中完成地理配准。
