Base map CR 1:25,000 - colour seamless - 11200455

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数据集采用源自捷克共和国地理数据基础库（Fundamental Base of Geographic Data of the Czech Republic, ZABAGED®）与捷克共和国地理名称数据库Geonames的数字技术制作。其数据直接取自技术线路IS SMD的Data10制图数据库。栅格数据分辨率为800dpi，色彩深度为24位。数据以TIFF格式分发，采用LZW压缩。输出单元为边缘与S-JTSK基准面坐标轴平行的5×5千米分幅。各分幅通过文本文件（TFW）完成对应坐标系下的地理配准，支持S-JTSK Krovak EN与WGS 84 / UTM第33N带两种投影。
